Dear friends and employees of our company,

2009 has become what the augurs were predicting it would be

last autumn, namely one of the worst economic crises since the

2nd World War. A crisis that began in the financial sector but has

now taken a grip on large parts of what is termed the real economy.

The automotive industry and the mechanical engineering

industry are the ones that have been hardest hit. Even entire

national economies, such as those of Spain and Great Britain and

various Eastern European countries, have found themselves in

serious difficulties.

Nor have the current developments left the foundry sector entirely

unaffected. Many companies that we think of as colleagues,

and especially ones that supply a large proportion of their output

to the automotive industry, are facing serious problems.

We are happy to say that our customers and business partners,

and hence we ourselves, are not so badly affected by this crisis.

There has been almost no change in the investment that our

most important customers, the public supply and disposal utilities

in the water and waste water industry, are making in the

renovation and development of their pipeline networks. Even

though, to our regret, it is rare for there to be any explicit mention

of pipeline laying in the government’s “stimulus packages”,

there are nevertheless a large number of far-sighted people in

responsible positions in the regional and local authorities who

have appreciated that the principle of sustainability and long life

is the very thing that must not be lost sight of in the field of public

supply and infrastructure. In this issue of inFORM we report for

example on measures of this kind involving ductile cast iron pipes

which have been taken in the Rhein-Hunsrück district (page 4),

in Siegen-Wittgenstein in North Rhine-Westphalia (page 5) and in

Linz in Upper Austria (page 8).

Our business policy is to focus on sophisticated areas of application

for our pipes and this has allowed us to work on some interesting

projects in regions that have otherwise been quite badly

shaken by the crisis. You can read about the major investment

being made at Palm Paper’s paper mill in King’s Lynn on England’s

North Sea coast on page 10 and about the water supply

project at Costa Ballena on the Andalusian coast on page 11.

From the United Arab Emirates we can report the implementation

of some spectacular projects involving our ductile pressure

pipes. And the ductile pile has shown convincing proof of

everything it is capable of in the desert sand of Abu Dhabi (see

page 12).

Many of our business areas are even managing to be quite unaffected

by the crisis because they are taking advantage of the

trend towards environment-friendly technologies. There is a

boom at the moment in investments in hydroelectric power involving

ductile cast iron turbine pipes of a kind that has almost

never been seen before. We have reports on this subject from

Garmisch-Partenkirchen in Bavaria (page 6) and from the Swiss

canton of Wallis (page 7).

After the last long and successful season, preparations are now

beginning in the Alpine winter sports resorts for the 2009/2010

skiing season. We are delighted to say that we were given the

contract for what is, at the moment, the most prestigious of all

snow-making projects. The first delivery of ductile pipes and fittings

for the snow-making systems in Sochi in Russia, where the

Winter Olympics are being held in 2014, is already underway.

Read our report on this on page 17.

In view of these developments, which have once again enabled

us to bring you, in the present issue, another edition of inFORM

packed full of interesting articles, we are confident of surviving

this period of crisis comparatively unscathed. Conversations we

have had with our customers and partners at important exhibitions

for the industries concerned such as Wasser Berlin and

Interalpin in Innsbruck (page 18) have confirmed this view.

This is why there is no change in the investment we are making

in our employees. You can see the newest faces on page 27.

And once the hard work has been done, no-one is going to stop

us enjoying ourselves. This year’s “Ramma Damma” day of action

in Hall was once again a complete success. See our report

on it on page 26.

There has by the way been a very special celebration in Tyrol

in 2009 in form of the commemorative year for Andreas Hofer.

With the Tyrolean roots of our group of companies, we naturally

felt it incumbent upon us to look at Hofer and his year in some

detail (page 22).

So we trust that this time too we have succeeded in bringing

together for you an informative and entertaining range of topics

drawn from our company. The holidays will soon be here, so

maybe it will be just what you need to read or take with you on

your journey.

We hope you have a lovely and relaxing summer!

“ R h e i n H u n s r ü c k W a s s e r ” :

w e l l s e r v e d b y d u c t i l e c a s t i r o n p i p e s

Let the drinking water flow!

The Zweckverband RheinHunsrück Wasser

utility supplies drinking water to around

90,000 people in the region of the Hunsrück

range of mountains and hills. They

include, amongst others, the inhabitants of

the town of Boppard on the Rhine. The untreated

water is pumped from wells in the

region of the Neuwieder Basin and is treated

in the waterworks at St. Sebastian on

the Rhine. Damage had occurred in the

past to the 14 kilometre long main supply

pipeline that runs from there to the highlevel

service reservoirs in the Hunsrück

range. The pipeline, which is 5 years old,

showed damage from pitting. In order not

to jeopardize the supply of good drinking

water to the populace, the Zweckverband

therefore decided to replace the entire

pipeline. In view of the fact that the safety

of the drinking water had to be maintained

even during the laying time, careful preparations

had to be made.

BGW were involved in the planning procedure

at an early stage, so that it could make

it clear what advantages ductile cast iron

pipes with a cement mortar coating have.

And it was successful at this, because the

Zweckverband decided to use this safe

material for by far the largest sections of

the pipeline, the route of which runs

through the sometimes difficult terrain of

the Hunsrück range.

The 1,400 metre long section of the pipeline

from the intermediate pumping station

at Silberberg to the Hellerwald high-level

service reservoir was finished late in the

autumn of 2008 and it was put into service

once the pressure testing was successfully

completed.

Because of the varied soil conditions but

the relatively straight path followed by the

pipeline in this region, ZMU ductile cast

iron pipes with restrained joints were

used.

In parallel with this, 1440 metres of DN

500 Buderus pipes and 140 Metre of DN

400 pipes were laid in a further section in

the Buchholz area of the district of Boppard.

The route followed was unusually

complicated in this section. At two points

crossings were made below the B 27, the

well known Hunsrückhöhenstraße road.

Cast iron pipes were also laid below the

Rhein-Mosel-Straße, a country road that

carries a lot of traffic, and below the

trackbed of the Hunsrück railway, which

was done by trenchless laying in a protective

pipe.

“This was another case where the ease of

laying of our pipes proved particularly helpful”,

reports Harald Oster of BGW’s sales

office in Koblenz, “because even though

the company doing the work, Walter Feickert

GmbH, only got approval for a narrow

strip of land to work in for the section running

parallel to the Hunsrückhöhenstraße,

the laying work went ahead smoothly. The

Feickert company, who we’ve already successfully

completed a large number of

projects with in the past, was, as always,

very satisfied with our technical support.

We can now get ready for another section

of the main supply pipeline. We’ve got the

contract for that as well. 4400 metres of

DN 500 ductile cast iron pipes with a cement-mortar

coating are going to be laid.

Before we can start the laying work however

we’ve got to wait until the bird breeding

season is over, because the pipeline will

run through a so-called FFH area. These

are special protected areas which have

been set aside under the EU’s Flora, Fauna

and Habitat Directive and whose purpose

is to safeguard plants, animals, birds and

types of habitat.”


T h e W a s s e r v e r b a n d S i e g e n - W i t t g e n s t e i n :

A g o o d e x p e r i e n c e w i t h B u d e r u s p i p e s

Ductile cast iron pipes show their reliability over more than 190 kilometres

For more than 55 years now the Wasserverband

Siegen-Wittgenstein (WVS) has been

supplying the district of Siegen-Wittgenstein

in North Rhine-Westphalia with high

quality drinking water. What it uses to do

this are principally two dams, the Obernau

dam with a storage capacity of 14.9

million cubic metres and the Breitenbach

dam with a storage capacity of 7.8 million

cubic metres. In the district there are

areas surrounding water extraction facilities

in which certain types of soil use are

restricted or prohibited by law and these

cover around 4 square kilometres. 90%

of them are forest or woodland with no

permanent human population.

Elsewhere however there are 00,000

consumers and so that every one of them

can obtain drinking water of excellent

quality the WVS operates not only some

quite small extraction facilities but also two

large treatment plants in Hilchenbach-Allenbach

and Netphen-Dreis-Tiefenbach,

24 high-level service reservoirs, 27 pressure-raising

systems and a network of

transporting pipes covering a total length

of 06 kilometres. The treated drinking

water is passed on to the towns and communities

in the district of Siegen-Wittgenstein

and to neighbouring municipalities in

nearby Hesse and is distributed by these

to the end customers.

Ductile ahead by a nose

Of the 06 kilometres of transporting

pipes, the share that ductile cast iron pipes

of nominal sizes from 100 mm to 600 mm

have at the moment is 192 kilometres.

That’s 64%! For the good of its customers,

the WVS is concerned in all respects

with ensuring the very highest standards

of safety and quality. The detectable substances

contained in the water are well

below the permitted limiting and guideline

levels laid down in the German drinking

water regulations. Regular examinations

by the government monitoring bodies

prove the excellent quality of the drinking

water.

The need for heavy investments is going

to continue

“Buderus’s ductile cast iron pipes are

one of the most reliable ways of achieving

one’s aims”, says Friedhelm Kleinblotekamp,

Head of German Sales, “but

in the course of tendering procedures for

contracts placed by public bodies we are

having to go over the same ground again

and again to show what we can do. Over

all the years that we have worked together,

we have supplied the Wasserverband

Siegen Wittgenstein with ductile cast iron

pipes for drinking water of a variety of

types starting with types with TYTON ®

joints and progressing through BRS ® joints

to BLS ® joints.”

The Siegen-Wittgenstein district is the

most heavily forested and wooded in Germany

and its most characteristic feature is

the Rothaargebirge mountain range with

its landscape typical of a relatively low

mountain range. Because of the acid soils

that are frequently encountered, it has

been predominantly pipelines with a cement

mortar coating that have been asked

for and used over the past few years.

“Pipe laying is usually done in open cuts”,

says Dirk Müller, CEO of WVS, “but in special

cases the pipes have been laid without

a trench by the horizontal directional drilling

technique. We are expecting the need

for heavy investments to continue in the

future.”

Drinking water supply and recreation

in an area close at hand in harmony

with one another

Although there are water protection areas

all round the two dams, hikers, anglers and

other enthusiasts intent on their favourite

recreation will find nothing to stop them

from enjoying themselves on the surrounding

tracks and paths that have been

specially laid out, because the WVS has,

so far, refused to put up any barriers or

hedges. For nature-lovers from further

afield, the area around the two dams is a

favourite destination for excursion trips.

Looked at like this, the supply of drinking

water and recreation without the need to

travel too far have managed to achieve a

peaceful co-existence.

R e c o r d h e a d a t G a r m i s c h - P a r t e n k i r c h e n ’ s “ E s t e r b e r g ”

h y d r o e l e c t r i c p o w e r s t a t i o n

3600 metres of ductile cast iron pipes carry spring water to the power station

Once upon a time the Esterberg springs

supplied the whole of Garmisch-Partenkirchen,

but recently they have only been

used as an emergency supply. Although this

is a function they still perform today, an additional

use has now been found for them.

For a short time now the water has also

served to generate electricity. The head of

water available for this is 502 metres, the

record head in Bavaria.

The construction firm that was given the

contract built a new main collector duct

for the Esterberg springs at 119 metres

above sea level and at 691 metres above

sea level, within the city limits of the market

town of Garmisch-Partenkirchen, it

built a generator building that was built directly

onto an existing transformer station.

A pressure pipeline .6 kilometres long

was laid between the two.

Rock made the laying work more difficult

Even when the work was being planned it

was clear that severe demands would be

made both on the material of the pipeline

and on the skills of the laying team. The

terrain is very rocky and about 1,600 cubic

metres of rock needed to be dug out

to allow the pipeline to follow its planned

route. This was no small feat and it proved

to be a real challenge for the firm doing the

The Esterberg springs

Laying work in rocky terrain

work. When selecting the material for the

pipes, the representatives of the municipal

authority wanted to be sure they were

on the safe side. In view of the maximum

operating pressure of 52 bars, of the variations

in pressure that could be expected

with the long turbine pipe and above

all of the very difficult ground conditions,

they opted for ductile cast iron pipes from

TRM. There is no other pipe material that

provides such large safety margins. To allow

for the rocky terrain, pipes with a cement

mortar coating were used for twothirds

of the pipeline. The part of the pipeline

that was laid below roads and footways

is protected by a polyurethane external

coating bedded in gravel, to prevent the

pipes from being damaged by the coarse

material produced by the digging out of the

rock. The entire pipeline is of DN 400 size.

After the time-consuming laying work, the

final results were very satisfying. “In the

end everything went very well. There are

no high spots at all along the pipeline so

it is virtually self-draining”, was the report

that Josef Grasegger, Head of the Electricity

Department at Garmisch-Partenkirchen’s

Municipal Utilities Authority, gave to

the trade magazine zeK (Zukunftsenergie

und Kommunaltechnik – Energy for the

Future and Technology for Local Authorities)

in its October issue.


The run of pipeline just before the generator

building

Successful entry into operation

A trial run of the system has been going on

since January 2009 and there have been no

faults. With the given head of 502 metres

and a design flow of 154 l/s the nominal

output is 6 6 kW. The electricity generated

is fed onto the network that Garmisch-

Partenkirchen’s Municipal Utilities Authority

itself operates. The power of the

Esterberg springs is expected to generate

around .1 gigawatt hours of clean electricity

every year. The system at the foot of

the Wank mountain thus looks to be a very

economical proposition. The municipality,

with its new power station able to generate

enough electricity for roughly 700

households of four people, will eventually

be able to take advantage of the new feedin

tariff of 12.67 cents/kWh which came

into force on the 1st of January this year.

This means that in less than 10 years the

system should have paid back the entire investment

cost of 1.7 million Euros.

The new power station also saves the atmosphere

from some 2960 tonnes of carbon

dioxide every year. And it can still do

its job as an emergency supply of drinking

water. There is a branch pipe installed in

the pressure pipeline so that, if it comes to

it, a switch can be made at any time from

the supply of electricity back to the supply

of drinking water.

For this ski-sports centre in the Werdenfelser

Land, the power station is one more

way of boosting its energy self-sufficiency.

And the effort to be self-sufficient is continuing.

The intention is that in ten years

the municipality, which has 26,000 inhabitants,

will itself be producing around 40%

of the energy it uses.

The Estergebirge mountain range

Anyone who drives from Munich in the direction

of Garmisch-Partenkirchen and has

reasonable weather will see the Estergebirge

mountain range in all its majesty. A

steep, forbidding face which extends to

heights of up to 1300 metres stretches

from Eschenlohe to Partenkirchen. For

many people however the range is just a

blank spot on the map and is very much

overshadowed by its famous neighboring range the Wettersteingebirge, which

contains Germany’s highest peak, the Zugspitze. The Estergebirge range is part

of the Northern Limestone Alps and is one of the largest continuous regions of

karst in the Bavarian Alps. In this region, rainwater and melt water disappear into

cavities and fissures, collect below the ground and finally return to the surface

as a karst spring. The best known of these is the Kuhflucht spring on the southwest

face of the Hoher Fricken mountain, which has a catchment area of around

five square kilometres and is situated in

the middle of a vertical wall of rock. Water

literally shoots out of the mountain there,

particularly while the snow is melting or after

heavy rain. After a long dry spell or in

winter the water level drops in the system

of caverns and then the unassuming massif,

which has the Krottenkopf as its highest

peak, becomes the stuff of dreams for

speleologists and potholers. Some of the

underground systems have still not been

explored even today.

A small hydroelectric power

station in harmony with nature

and the environment

The municipality of Unterbäch, a village in

the Swiss canton of Wallis, has for many

years been operating a small hydroelectric

power station that uses the water of

the Milibach stream to generate electricity.

Up until two years ago the water, having

passed through the turbine, flowed

back into the Löübbach without any further

use being made of it. That needed

to change. What the village, which is situated

on a plateau to the south of the valley

of the river Rhone, planned to do was

to collect this unused water, together

with the cleaned waste water from the

water treatment plant, and put it through

another turbine in the hamlet of Turtig.

TMH Thomas Hagenbucher, BGW’s

Swiss sales and distributing partner, supplied

DN 500 ductile cast iron pipes with

a sulphate resisting cement lining for the

1,609 metre long pressure pipeline. For

the sections of the pipeline that had to

be laid in rock, the decision was made to

use the proven cement mortar coating.

The pressure pipeline passed all the tests

without giving any cause for complaint.

In December 2008, the municipal newssheet

“Dreiblatt” (Cloverleaf) proudly reported:

“Thanks to the exemplary work

that was done in planning and constructing

the small hydroelectric power station

in Turtig, electricity has been produced

over the past year without any real problems.”

O n l y t h e b e s t f o r “ E u r o p e ’ s b e s t d r i n k i n g w a t e r ”

At an international water tasting held during

the European Union’s Green Week in

Brussels in the summer of 200 , Linz’s

drinking water was chosen as “Europe’s

best drinking water”. Via the waterworks,

the drinking water of Linz is extracted from

the flow of groundwater under the Welser

Heide plain and from the flow of groundwater

taking place parallel to the Danube

in the Eferdinger basin to the north and in

the Urfahraner basin. The quality of this

water is outstandingly good, so much so

that no additional treatment is needed. The

drinking water is passed straight on to the

consumer.

Environmental protection brings an

increase in quality

For more than 100 years, the Linz waterworks

in the city on the Danube have been

seeing to the efficient operation of the water

supply systems and ensuring that superb

drinking water flows from Linz taps.

Since 199 , LINZ AG, the company operating

the waterworks, has been running a

program of environmental care on the land

it owns in the water protection areas. This

includes the planting of copses of trees appropriate

to the locations to allow as nearly

natural a state as possible to be achieved.

The reintroduction of species of plants,

animals and birds driven out in the past is

being helped by steps such as the setting up

of nesting boxes. These measures benefit

not only the quality of the water but also

the environment.

Some 400,000 people in this capital of

the state of Upper Austria and in 2 surrounding

municipalities are the beneficiaries

of this responsible water management.

Linz’s water supply puts its trust in ductile cast iron pipes

There are thorough quality controls on

the resource and these include the constant

care given to the network of pipes,

which is more than 1, 00 kilometres long

and is fed from six waterworks (Scharlinz,

Goldwörth, Plesching, Fischdorf, Heilham

and Haid).

TRM as a reliable partner

Quality is a primary concern, which is why

LINZ AG also attaches very great importance

to the material of the pipes. This is

the reason for its partnership of more than

60 years with Tiroler Röhren- und Metallwerke

AG.

When parts of the pipe network are being

replaced and new supply pipes are being

installed, the people responsible for the

water supply in Austria’s third largest city

put their trust exclusively in pipelines of

ductile cast iron with a PUR TOP coating

and easily assembled BLS ® / VRS-T ® joints.

The PUR TOP coating, a development by

Tiroler Röhren- und Metallwerke AG, is a

polyurethane coating of increased thickness

(420 µ), with an additional impactprotection

strip wound on top. PUR TOP

pipes are used mainly in corrosive soils.

The oldest pipes of grey cast iron in Linz

have been in use since 189 . For safety reasons,

these old pieces of piping are being

replaced section by section.

A key part of the Linz water supply system

was renovated for this reason in the autumn

of 2008. The old DN 500 and DN 400

pipes of grey cast iron were replaced for a

length of around 1000 metres in the section

running to the Gugl high-level service

reservoir. The preliminary planning had to


e very exact because this area of the city is

very steep in places and the aim was for the

laying work to be completed in as short as

time as possible to minimize any problems

to the population and interference with

traffic in the densely built-up area. Thanks

to the decades of experience that Hubert

Traunsteiner (Operations Manager at the

Water Department) has had and the excellent

collaboration with TRM’s Applications

Engineering Division, the project was completed

in a laying time of only four months

despite the difficult terrain.

“We are very happy with the way that all

the laying work was handled and in line

with our resolve to set the very highest

quality standards for the pipe material we

made the right decision, namely to opt for

TRM’s ductile cast iron pipes. The BLS ® /

VRS-T ® joint system not only proved very

“laying-friendly” but will also ensure the

sustained long-term safety of our drinking

water supply“, was how Hubert Traunsteiner

summed things up on the successful

completion of the renovation work.

Linz – European Capital of Culture 2009

For a long time Linz was considered the ugly duckling struggling to keep up

with its beautiful big sisters Salzburg and Vienna. Its name was only known

to many non-Austrians because of the celebrated Linzer torte. Yet this sternfeatured

beauty on the Danube has not only blossomed on the outside but

has also set out to make culture a real part of its existance. Today the city

is no longer just the name of the cake made with jam and short pastry but

a little Eldorado for the aficionados of culture – and not just from Austria.

The city has had a difficult journey and the culture builders who wanted

to establish Linz as a modern city had to contend with repeated cases of

internal resistance. The population for example were only too ready to call

the Lentos Museum of Art (see the photo above), a spectacular building

in the shape of a bridge on the banks of the Danube which was opened

in May 2003, a “shoebox”. Guests from all over the world come to “Ars

Electronica”, the festival of media art which every year focuses on issues in

the field of social policy, but there were only a few, young, visitors from Linz.

Even in his day the poet Stefan Zweig quipped: “Linz rhymes with province

and provincial it is”. And that is why the one thing above all others that

the city would like to achieve in 2009, its year as the Capital of Culture, is

– more internationality.

But it would be unjust to the city to consider it only from one point of view.

As one of Austria’s largest industrial metropolises, Linz has more jobs than

inhabitants and the region is close to a state of full employment. Environmental

steps have been taken and requirements laid down for the industrial

companies to improve the quality of the air to allow the city to shed its

problematic environmental image. Today, the “steel town” counts as one

of Austria’s cleanest cities, where the quality of life is high and there is an

awareness of itself as a technology-based and knowledge-based industrial

city that takes culture and the environment just as seriously.

Kings Lynn

Satisfaction guaranteed by the BLS ® problem solver

In September 2009, the family company

Palm Paper, leaders in the production of

newsprint and corrugated case papers,

will be putting Europe’s most up-to-date

paper mill into operation in King’s Lynn

in England. In the future, 400,000 tonnes

a year of high-grade newsprint produced

entirely from waste paper are going to be

produced there. On 11 December 2008

a topping-out ceremony was held at Palm

Paper and early in 2009 the installation

began of the world’s largest machine for

making newsprint.

Water for papermaking

What do you need for making paper? Gigantic

machines, a variety of fibrous materials

and, above all, water!

Palm Paper’s mill has been built on the

Great Ouse river. The water for paper

production will be drawn from the flood

relief channel and will then be cleaned by

means of sand filters. After the manufacturing

process the waste water, having been

cleaned in the water treatment plant, will

be fed back into the Great Ouse. The Beton

und Rohrbau C.-F. Thymian GmbH &

Co. KG company was given the contract to

construct the water treatment plant. Surveys

revealed that the ground in the area

to be built on was part of the flood plain of

the Great Ouse and consequently would

be unstable. So, a material was needed for

the pipelines that could accept the possible

settlement.

For safety’s sake: BLS ®

Beton und Rohrbau, a Berlin company, decided

to use ductile cast iron pipes with

BLS ® joints because the material could

l a r g e s t p a p e r m i l l

the heights of cover, which were small in

some cases, and because the flexibility of

the joint would allow it to compensate for

the expected movements of the soil. By

using the BLS ® pipes with their restrained

joints it was possible to dispense with the

use of concrete thrust blocks. 700 metres

of DN 500 BLS ® pipes were laid to carry

the industrial water to the production plant

and 40 metres of DN 600/800 BLS ® pipes

were laid to carry the waste water away.

The pipes, wrapped in geo-textile, were

bedded in sand.

At the end of May, all the work was completed

and the laying manager, Bernd Klippel,

could breathe a sigh of relief: “It wasn’t

exactly the easiest of sites because it was almost

impossible to estimate the soil resistance.

So we were more than happy to be

able to get round these imponderables by

using the BLS ® pipes. In spite of the difficult

soil conditions, the laying work progressed

very smoothly and, thanks to the uncomplicated

joint, without any problems”.

King‘s Lynn

King‘s Lynn is an industrial town

and port with a population of

35,000 in the county of Norfolk

in England and it has not only

had an eventful history but also

has a highly diversified economy.

A large number of companies

who are world leaders have

set up shop in King’s Lynn, such

as Campbell’s for example, the

world-famous soup-maker. The

setting up of the Palm paper mill

will underline the economic importance

of the town.

Close to the Custom House there

is a memorial commemorating

the man who was probably King‘s

Lynn’s most famous son, George

Vancouver, who explored and

mapped the north-west coast of

America in 1792 as the captain of

the Discovery. The Canadian town

of Vancouver and Vancouver Island

lying out to sea from it were

named after him.

ZMU pipes to ensure a supply of drinking water

in the province of Cádiz

To improve the drinking water supply to

the Andalusian tourist resort of Costa Ballena

and to the adjoining towns of Rota

and Chipiona, an 8800 metre long pipeline

had to be laid to take water from the

underground Agostada reservoir. Due to

the number of tourists visiting this area

on the Costa de la Luz, there is a sharp

rise in the demand for drinking water in

the peak summer months. To cover these

peak levels, the pipeline was planned for a

pipe diameter of DN 800 and a flow rate

of 729.65 litres per second.

Special features of the soil

In planning the route, which snakes its way

through vineyards and orchards, allowance

had to be made for some problematic soil

conditions. A metre below the surface of

the ground there is clayey soil extending

to depths of up to .5 metres. Some initial

fears that they could be “expansive clays”,

clays of a particular type that swell or shrink

as a function of their moisture content,

were overcome by means of extensive soil

surveys. The increase or decrease in volume

of the clay due to swelling or shrinkage

is less than %. Yet even changes in volume

of this size are a problem for the covering

layer because they have an adverse effect

on the load-bearing capacity of the soil.

Overall, the soils were classed as highly to

moderately corrosive.

ZMU as the means of choice

To provide a pipeline with sustained and

reliable protection against fracture and

against damage by the corrosive soil,

Buderus’s partner in Spain, the Construtec

company, suggested to the planners

that they use Buderus pipes with a cement

mortar coating (ZMU), which are suitable

for all types of soil and provide adequate

safety margins. This external protection

is very strong and will withstand high mechanical

loads. To add to this, there is the

protective action of the zinc coat below

the cement mortar, which actively protects

the iron in the unlikely event of damage extending

the whole way through the cement

mortar. The customer, PLODER-UICESA,

and the authorities responsible for environmental

protection were convinced by

the advantages of ductile ZMU pipes. The

decision in favour of this tried and tested

pipe material was made above all because

of its wide safety margins, which were absolutely

vital in view of the unpredictable

and uncontrollable stresses due to the geological

conditions.

Deliveries of the pipes will be taking place

up until mid-July and all the work, during

which Construtec will be providing the

company doing the work with applications

engineering advice in close consultation

with Buderus, will be completed in latesummer.

A young holiday resort

Costa Ballena is situated in the province

of Cádiz on Spain’s border with

Portugal and is a relatively new holiday

resort. The planning of the resort

and the legislation affecting it were

very clear and strict – the buildings

could not be more than three floors

high and had to be at least 300 metres

away from the beach. The resort

covers an area of 400 hectares and

only 25% of this area is occupied by

buildings. The really great attraction

is the golf course designed by José

María Olazábal. It covers an area of

100 hectares and both occasional

golfers and those who play to a high

level of performance will get their

money’s worth here.

TRM and BAUER complete a successful pile test

Technology experts Linde Group and the

Abu Dhabi National Oil Corporation (AD-

NOC) are building two giant air separation

plants in Abu Dhabi (United Arab Emirates)

through Elixier, the joint venture company

they have set up. The total investment

will be some 800 million US dollars. The

new plants will be connected to the local

supply and pipeline network at the end of

2010 and from then on will be supplying

nitrogen for pumping natural gas. Deep

foundations are being used to ensure the

safety of the site and the call for tenders

envisaged drilled piles for these. Clearly it

had to be shown that there were advantag-

es to using ductile piles. Drilled piles contain

a high proportion of concrete and this

might cause logistics problems in the UAE.

Also, at temperatures of up to 55° C the

concrete could become difficult to process

so the mixing water would have to be

cooled. After numerous meetings with the

authorities and with specialist foundation

engineers, TRM, together with Bauer International

FZE of Abu Dhabi, carried out

a pile test in May which attracted widespread

attention. The local building authority,

the Abu Dhabi Municipality, called for

a working load of 100 tonnes per pile with

a safety factor of 2.5, i.e. a test load of 250

tonnes. The DN 170 mm ductile pile was

driven into the ground by a hydraulic hammer

(working weight of 4,200 kg) applying

an impact energy of 6,000 kN. The criterion

set for driving (20 sec/1cm) was met at

12 metres. There was then a hydraulic pile

test which gave excellent results. When the

working load of 1000 kN was reached,

we had a settlement of 9.46 mm, which

was equivalent to a permanent settlement

of 2.0 mm once the load was removed

and once again confirmed the outstanding

properties that ductile cast iron has as a

material. These results have now created

a very good background against which customers,

planners and general contractors

will be able to see the ductile pile as a serious

alternative to drilled piles.

Yas Island

Drinking water flows

through Buderus pipes

Yas Island is considered to be the sports

and leisure centre of the United Arab

Emirates and is only 0 minutes away from

the capital, Abu Dhabi, by car. This low island

of sand, surrounded by mangroves, is

currently the biggest and most important

building site in the sheikdom on the Persian

Gulf. For around 40 billion dollars, a

breathtaking new part of the city is being

created here. The chief investors in the

project are the country’s ruling family, the

Al Nahyans. As well as a Ferrari theme-


park, several golf courses, water parks,

polo fields, a riding centre, shopping malls

and luxury hotels, there is one very special

attraction that the future infrastructure of

the island will boast – the Formula 1 motor

racing circuit, the Yas Island circuit. On

0 October 2009, the cars will be accelerating

away from the starting grid for the

Abu Dhabi Grand Prix. Time is pressing

and the pressure won’t let up. Many building

companies have been taken away from

other sites in the country so that the whole

of the infrastructure project can be completed

in time.

The supply of drinking water will undoubtedly

have a central role to play in this new

showpiece of the emirate. More than

enough fossil fuel contrasts with far too little

water. The main source of drinking water

in this desert country on the Gulf is sea

water treated in desalination plants which

is fed to storage tanks. This is also the case

with the prestigious Yas Island project.

For the main pipeline from the desalination

plant to the water storage tank, BGW/

B.P.S. is supplying 1. kilometres of DN

900 and DN 1000 ductile cast iron pipes,

10% of which will have BLS ® restrained

joints.

“You might almost think”, reports Leon

Bauer, Operations Manager of Buderus

Pipe Systems (B.P.S.), the sales and distribution

company in Dubai, “that the efforts

we have made over the past few years in

Abu Dhabi have meant that nowadays calls

for tender almost always specify the ductile

cast iron pipe. It is Buderus that has

made the grade in Yas Island. One of the

main reasons for this has been the satisfactory

experience that the contractors

Nael & Bin Harmal have had on previous

projects both with the reliable material

and with our dependability as suppliers.

At the end of the day – not least because

of the Formula 1 circuit – the project is

very much in the public interest and people

wanted to rule out any possibility of delays

caused by broken promises to deliver.

We were able to give them the quality and

logistics they expected.”

Supplying drinking water in the oasis city of Al Ain

An order worth four million Euros goes to Buderus

Al Ain is the second largest city in the

emirate of Abu Dhabi. The one-time

oasis, which still exists in the city centre

as a palm grove for pedestrian access, is

situated about 150 km to the west of the

capital on the border with Oman. Thirty

years ago Al Ain was still a village, but the

city at the foot of the crag called Jebel Hafeet

has long since developed into a modern

metropolis with some 4 0,000 inhabitants

– and the population is still rising.

The city spreads over a lot of ground and

covers an area equal to that covered by

Paris. However there are no high-rise

buildings here as there are in the capital

Abu Dhabi. No building is more than six

floors high. The “Garden City”, as it is

called in the Gulf region, owes the rapid

pace at which it has developed to the

founder of the United Arab Emirates and

their former president, Zayid bin Sultan Al

Nahyan, who was born here. He wanted

to see his emirate, and above all his place

of birth, as a green place.

The sharp rise in the population (there

are also many foreign workers living here)

made it necessary for the drinking water

supply to be urgently updated. The Ministry

of Water of the emirate has put the

remedying of the poor supply high on

its list of priorities, especially as further

growth is expected in Al Ain. The capacity

of the drinking water supply system has to

allow for this future development.

To BGW the situation was clear – it would

face severe competition on the Al Ain

projects I & II. And that was why it was

all the more satisfying that in the end the

order, worth 4 million Euros, did go to

Wetzlar.

“Through B.P.S., our sales and distribution

company, we are going to be supplying a

total of 25.2 kilometres of ductile cast iron

pipes of nominal sizes from 100 to 900

millimeters. About 10% of the pipes will

have BLS ® restrained joints”, says Peter

Waßmuth, the sales manager responsible

for Africa and the Indian sub-continent at

Wetzlar.

The contractor in this case is Al Salmeen

Contracting and their decision was similar

to that on the Yas Island project, namely to

opt for BGW, firstly because there were

special coating requirements that BGW

were able to meet and secondly because

BGW were able to make the first part

delivery by as early as April 2009. A total

of some 4,900 tonnes are being shipped

first by train to Antwerp and from there

by ship to the Gulf. Trucks carrying loads

of tightly packed pipes then take over for

the final stretch to the city in the desert.

Salzburg is getting a new main

railway station. The future

through-station is going to be a

national and international transport

hub fully up to the demands

of the modern age of rail travel.

Excellent customer facilities,

short distances to walk, changes

of line without going through

barriers, optimum information

for passengers, a central

concourse with shops and a

unique architectural design that

integrates parts of the old station

that have listed-building

protection into the very latest

in station infrastructure will be creating a

new gateway to the town so celebrated

for its festival. With a total investment cost

of well over 200 million Euros, the conversion

is at the same time a prerequisite

for the linking in of the suburban railway

lines – a project that has for many years

been Salzburg’s extremely important for

local and commuter travel. With up to

25,000 passengers a day passing through

it, Salzburg’s main railway station is one

of the biggest railway stations in Austria

and a very important transport hub in the

Austrian state of Salzburg. The first sod of

earth was turned for this immense project

on 7 November 2008. Everything should

be completed sometime in 2014.

Ductile driven piles make for secure bridge foundations

It couldn’t be done without TRM

Um den Hauptbahnhof optimal an die To

allow the main railway station to be properly

connected to the three-line track

running to Freilassing, the railway bridges

over the Plainstraße and Rainerstraße

roads in the west of the plot of railway

land are being replaced. The 100-year-old

steel bridges are being taken down and

replaced by bright newly-built ones. The

current height of free passage of .6 metres

is being raised to 4.2 metres and 4.6

metres.

The geological and hydrological survey

revealed that under the strip foundations

there is a four metre thick layer of gravel.

Below that, to a considerable

depth, there is the notorious

“Salzburg lacustrine clay”. “This

is a not completely mineralized

silt-like clay that will not carry

any sort of load”, explains Thomas

Aumüller, TRM’s Head of

Cast Iron Pile Sales. “The invitation

to tender for the loadbearing

systems for the two

bridges therefore envisaged a

deep foundation. Because of

the good experience we had

had with ductile piles for bridge

and anti-noise wall foundations

on the neighbouring Taxham lot,

this was another case where we were able

to win out over small drilled piles.”

In March 2009 the appropriate milestone

was reached and the building of the new

bridges began.

The foundation work went ahead perfectly

smoothly”, says Aumüller. “Altogether,

we delivered 15,000 metres of

small ductile cast iron driven piles to the

construction site. At the pile lengths that

were required of 25 metres for a pile load

of 500 kN and 0 metres for a pile load of

600 kN, our pressure grouted TRM piles

gave proof of their excellent economy,

which was apparent mainly from the quick

and uncomplicated driving. The work was

completed in 40 working days.”


Frankenallee in Frankfurt

A drinking water pipeline: NRM-Netzdienste

decides in favour of BLS ® pipes

In Frankfurt am Main, there is a 17.4 kilometre long DN 700

drinking water pipeline of gray cast iron pipes that was laid between

1920-1940 that needs to be replaced section by section.

During the preliminary planning, the hydraulic calculations revealed

that optimum operation could be ensured by reducing the

nominal size to DN 400. The background to the outcome of the

preliminary work is as follows: In Germany, the consumption of

drinking water by the population and industry is falling. For this

reason, a reduction in the hydraulic cross-section of a pipeline is

often advantageous to operators because the speed of flow of the

water is raised and the time for which the drinking water remains

in the pipeline is shortened, which often prevents hygiene problems.

As part of this overall operation, a 1, 00 metre long section

of the old pipeline is first being replaced on the Frankenallee,

which runs parallel to the Mainzer Landstraße in Frankfurt’s Gallus

district. The customer, NRM-Netzdienste Rhein-Main GmbH,

decided to use ductile BLS ® pipes for this. “The main reason for

this”, Heinz-Jörg Weimer of BGW’s sales office in Frankfurt tells

us, “was that in previous operations the experience that NRM-

Netzdienste had with our drinking water pipes had been good.

Added to this was the fact that the preference was to use the

relining technique for the Frankenallee section as, incidentally, it

had also been for other laying operations on the Alleenring ringroad.

For all pipelines that do not have many changes of direction

or lateral connections, replacement by this technique is always

more economical than relaying in open trenches. This is particularly

true of runs of pipeline below paved or macadamized surfaces

or in built-up areas, as is the case here on the Frankenallee.

Another 800 metres of DN 400 pipes are by the way shortly going

to be laid on the Friedberger Landstraße.”

Culvert under the Moldau at

Budweis

Drinking water pipelines pulled in by the

relining technique

In the course of the straightening of the Moldau between the

towns of Budweis (České Budějovice) and Hluboká nad Vltavou

in the Czech Republic, a culvert that was built some decades

ago had to be renovated. To allow for the drop in the demand

for water in the metropolis of Budweis in Southern Bohemia, a

reduction in the nominal size of the pipelines was to be made

at the same time as the culvert was rebuilt. The engineers at

our Czech sales and distribution company Buderus Litinové Systémy

(BGC) in Beroun therefore suggested the use of DN 500

ductile cast iron pipes with a 200 g/m 2 hot-dip zinc coat and a

blue epoxy coating and of restrained BLS ® joints. They also recommended

trenchless laying by the relining technique.

“We were able to kill two birds with one stone in this way,”

says Juraj Barborik, Head of Applications Engineering at BGC,

“because the DN 500 cast iron pipes could be pulled into the

existing pipelines consisting of DN 800 steel pipes. We achieved

the desired reduction in the nominal size of the drinking water

pipeline in this way and at the same time did the work at low

cost by using the relining technique, because with this technique

the money that has to be spent on laying is disproportionately

lower than with conventional laying techniques.”

In December 2008, two laying pits were dug on the banks of

the Moldau, the Czech Republic’s longest river, and the two

parallel pipelines, each 112 metres long, were pulled in just five

hours. The subsequent pressure testing revealed no causes for

complaint of any kind and the concreting of the culvert could

therefore be completed and the pipelines put into operation.

The culvert is one of four crossings of the Moldau in the region

of the town, which has a population of 95,000. “The quickly

assembled BLS ® joint confirmed the economic advantages of

the ductile cast iron pipes and the long technical life will mean a

sustained saving on operating costs”, says Barborik.

Well wrapped up for winter

Bridge pipeline of WKG pipes crosses

the Loire

WKG pipes are in pole position when it comes

to laying frost proof bridge pipelines. Even

when the temperatures are well below freezing

and the medium carried is still for quite

long periods, the thermal insulation stops it

from freezing. A coating of hydrochlorofluorocarbon-free

rigid polyurethane (PUR) foam

turns ductile cast iron pipes into experts at

coping with the rigours of winter. On openair

pipelines the rigid PUR foam is protected

against the effects of the weather by a folded

spiral-seam outer shell of galvanized sheet

steel or, if desired, of stainless steel.

“In the Loiret department”, explains Jeff Benoit,

an employee of BGW’s French sales and

distribution partner SOVAL, “there was a

problem with the pipeline that supplied water

from Sully sur Loire to Saint Père sur Loire. It

was an open-air pipeline, laid across a railway

bridge and dating from 1945, so it had been

around for a few decades. The little town no

longer had a reliable drinking water supply

and there had been outages, especially in cold

winters. We therefore decided to propose

Buderus’s thermally insulated pipes for the replacement

of the pipeline – there was no getting

away from the advantages of WKG pipes

and we used this to convince people.”

In March 2009, 420 metres of DN 200 thermally

insulated pipes and socketed bends were

delivered to the site at Sully sur Loire. The village

is well known for its castle, which was built in the 14th century

on the banks of the Loire.

The pipes were laid along the track bed of the railway line. Because

the railway service over the bridge had to be maintained,

the laying work had to drag on for two months. Sometimes work

even had to be done at night to ensure the progress of the laying

work. But take your time and the result is usually good or very

good, as it was in the case of the WKG site on France’s longest

river. The drinking water pipeline was commissioned without any

problems and in this coming winter it will demonstrate its advantages

to the full.

Feuerlöschleitung Neuhof

A tunnel for Neuhof

Drainage and fire-extinguishing pipes of

ductile cast iron

“It would be best if they were never used,”

says Karl-Wilhelm Römer of BGW’s sales

office in Kassel, “but if there’s an emergency

they have to operate reliably.” What

he’s talking about is fire extinguishing pipes

in tunnels. If a fire occurs, the firefighters

rely on having adequate amounts of water

available to them to put it out. For some

years now, those responsible for tunnel

building have put their trust in ductile cast

iron pipes to give them the safety capability

they need, which comes from the pipes’ high

resistance to internal and external stresses,

from the fire resistance and robustness of

the material and of course from the reliable

technique used to connect them. The latter

is of crucial importance in the case of pressure

pipelines, which the pipes used in the field of fire safety almost

always are. The position was the same in Neuhof, the little German

mining community in the state of Hesse where potash salt has

been mined for more than 100 years. Since early in 2008 virtually

all that can be seen in the village is a heavy construction plant. And

the reason for the heavy site traffic? A new seven kilometre section

of the A66 autobahn is being built to close the gap between the

Neuhof South junction and the Fulda South intersection and Neuhof

is where it begins. The key part of the section to close the gap

is a 1.6 kilometre long twin tunnel through the area of Neuhof. The

tunnel is being built by the open-cut technique in a cutting that has

been made through the high ground. On completion of the work

the tunnels will be completely covered with earth. This procedure

has to be followed because of the need to observe the anti-noise

and anti-emission regulations. As far as the supply of extinguishing

water was concerned, the people at Neuhof wanted to be on

the “safe and ductile side” because most important for technical

perfection is the right material for the pipes. For the , 00 metre

long fire extinguishing pipes, Buderus DN 150 pipes with the tried

and tested flexible BLS ® joints and a blue epoxy cover coating

are being used. As well as the fire-extinguishing pipes, BGW is

also supplying the pipes for draining the tunnel – ,000 metres of

Buderus DN 00 and DN 400 ductile cast iron pipes with a zinc

coat and a red-brown epoxy cover coating.

The complete section of autobahn is due to be opened to traffic

in 201 .


A winter’s tale at Willingen

Snow-making systems at Willingen work to

perfection

With an investment of 18 million Euros in the

development of its skiing areas, Willingen in

northern Hesse has taken its place in the top

league of German winter sports resorts. Since

the winter season of 2008, the snow-making

installation has been running perfectly and

has been making this idyllic venue for the Ski-

Jumping World Cup in the Waldecker Land

independent of Frau Holda, who, according

to Germanic folklore, controls the winter weather. The form and

scope of the project are unique among German skiing resorts.

Snow can be made on all of Willingen’s major ski slopes. The

infrastructure is designed so that at appropriate temperatures all

the main pistes can be given an adequate cover of snow in around

50 hours. “It is our ductile cast iron pipes that see to the smooth

flow of the snow-making operation on the ski slopes of the Ettelberg

mountain”, comments Uwe Strich of BGW’s sales office

in Thüringen. “We have supplied a total of around 1 kilometres

of ductile cast iron pipelines with BLS ® /VRS-T ® socket joints and

cement mortar coatings (ZMU). Together with the operators of

the snow-making systems, the community authority at Willingen

decided to go for Buderus pipes because there are advantages to

them from both the economic and safety points of view. When

ductile cast iron pipe systems are being laid, there is no welding

work that has to be done out in the field. This means a considerable

reduction in installation costs compared with welded pipe

systems. The nominal sizes of DN 80 to DN 00 that were used

have an allowable operating pressure of at least 64 bars and this

means a high level of safety for the snow-making operation.”

There are five main downhill slopes with a total length of seven

kilometres and some 50 modern snow-makers supply them with

the coveted snow. Ductile cast iron pipes are also used for snowmaking

at the big ski jump arena, the Mühlenkopfschanze. This

installation showed its reliability repeatedly at this year’s FIS Team

Tour, which was being held for the first time as part of the Ski-

Jumping World Cup. “We took the event as a good reason for

demonstrating the high performance of the ductile cast iron pipe

system in the snow-making field to representatives of the supply

and disposal industry. The systems on the Ettelsberg and at

the Mühlenkopfschanze ran like clockwork. These are the most

important German snow-making projects north of the Alps and

we are proud to have done our bit to enhance the quality of the

Willingen winter sports resort with our reliable cast iron pipes

and the high standard of our applications engineering advice,”

declares Karl-Wilhelm Römer of BGW’s sales office in Kassel.

The 2014 Winter Olympics at Sochi

TRM is supplying pipes and fittings for the

snow-making systems

When Sochi was selected to host the

22nd Winter Olympics on 4 July 2007,

the people of this South Russian town

on the Black Sea danced in the streets

and celebrated with plentiful supplies of

“shampanskoye”. Two years later, on 20

May 2009, it was TRM’s turn to celebrate.

The contract to supply 14.6 kilometres of pipeline and 1414 fittings

for the snow-making installations at the Olympics venue in

the Caucasus was in the bag: the total value of the order was

around 1.5 million Euros.

“It is quite clear that this most prestigious of all the 2009/2010

snow-making projects went to us because we are the technological

leaders in this field and because, given the large number of

fittings required, we were the only supplier who could promise

reliable and punctual deliveries,” reports Stefan Sterr, Head of

Special Products at TRM, “We can also provide the technical support,

and the best references in the market from satisfied customers.”

This was crucial for the customer because the snow-making

systems at the Olympic ski resort of Rosa Khutor are technologically

demanding. This is because the contours of the terrain are

steep and winding and the long supply runs to the systems cause

high pressure in the pipes. More than 12 billion dollars are going

into the provision of infrastructure and the development of sports

facilities. At first glance it seems rather strange that winter games

are going to be held there. Sochi is lavishly adorned with palm

trees, orchids and other exotic plants. The climate is sub-tropical

and gives Sochi an average of 200 days of sunshine a year. Look

upwards however and it becomes clear where the Olympics are

going to be held: the snow-capped peaks are part of the Caucasus

Mountains, whose highest mountain, Mount Elbrus, lies at a height

of 5642 metres. The skiing resort that Sochi has, Rosa Khutor, is

some 40 kilometres from the coast in the Krasnaya Polyana region

and from 7 to 2 February 2014 it will be the venue for the

Alpine competitions of the Winter Olympics. It will take 60 trucks

to transport all the pipes and fittings to the point where they are

going to be used in the Caucasus. In June, the first of these trucks,

loaded with the consignment scheduled for 2009, set off on their

journey of some 2000 kilometres to Krasnaya Polyana. The second

consignment will be following next year. The timetable that has

to be met is a tight one. The laying work has to be completed by

2010 and completion of the entire system is scheduled for 2011.

The test runs will be taking place a year later and in 201 the

Universiade is going to be held as a sort of dress rehearsal for the

Winter Olympics.

Growth in all areas

From 1 March to April 2009, innovative

products and services from the international

water and waste water industry

were on show at the 1 th WASSER

BERLIN exhibition. In spite of the difficult

economic environment, the leading European

trade fair for the water sector

managed to increase the number of exhibitors

and enlarge the exhibition space.

The cast iron pipes group had a 00

square metre stand on which it presented

itself as a global player in the water and

waste water industry under the slogan

The future is ductile”. It also used the

exhibition as a platform for making contacts

especially in the Eastern European

market, for which the potential growth

forecast in the fields of water and waste

water is extraordinary.

The main focus of the presentation was

“Trenchless Laying”. Friedhelm Kleinblotekamp,

Head of German Sales at

Buderus Giesserei Wetzlar GmbH,

summed up this year’s fair, and the company’s

appearance at it, as an industry

event of primary importance: “For us,

WASSER BERLIN is a springboard into

new German states and into many Eastern

European countries. We had invited

large numbers of customers and potential

customers and they came to see us in

Interalpin in Innsbruck

As suspected by insiders

and trade journalists, Interalpin

2009 was, after

the successful winter

season in 2008, better

attended than ever before.

18,100 trade visitors from all continents

once again turned Innsbruck into an

international metropolis for the cable car

and winter services industry and set a new

record for the number of visitors. From

22 to 24 April, Messe Innsbruck’s halls and

open-air exhibition grounds were so full

that it was almost impossible to squeeze

in. 500 exhibitors were delighted with the

enormous increase in the number of visitors

from France, Eastern Europe, North

America and Asia, which made it clear that

in spite of the economic crisis there is no

let-up in demand in the winter technology

sector.

On a 100 square metre stand, TRM showcased

the cast iron pipes group’s full range

of expertise in the construction of pipelines

for snow-making systems. Being shown as

totally new products were the DN 250 and

DN 00 MK single-socket bends with angles

of 11°, 22° and 0° and the DN 250/80,

DN 250/125 and DN 00/80 MMB all-socket

tees. The marketing brochure had been

completely redesigned in view of Interalpin

(more about this on page 24).

“Interalpin is undoubtedly the most important

technological trade fair for winter

technology in the Alpine region, and we

were able to make a particularly impressive

success at it with the completion of

the Rosa Khutor snow-making project in

Russia. The alpine skiing competitions of

the Winter Olympics are going to be held

there in 2014”, was how Stefan Sterr, Head

of Special Products, summed things up (see

our article on this subject on page 17).

The ÖVGW Annual

Conference in Graz

The Österreichische Vereinigung für das

Gas- und Wasserfach (ÖVGW – The Austrian

Association for Gas and Water) is the

independent voluntary body representing

all the Austrian operators of gas supply

networks, and just on 220 water supply

companies which supply some 5.4 million

people in Austria (67 % of the population)

with drinking water.

The 119th annual conference of the

ÖVGW was held from 1 to 14 May 2009

in Graz Town Hall. 560 attendees from at

home and abroad had come to the capital

of the Austrian state of Styria to attend

this event, rich in tradition, which brings

together gas-supply network operators,

drinking water suppliers and other industry

representatives. To open the conference,

Dr. Werner Beutelmeyer (of Market

Research) gave a picture of the general

mood of the population against the background

of the crisis. This was followed by

expert papers on subjects drawn from the

fields of natural gas and drinking water

which provided an excellent opportunity

for exchanges of thoughts and discussions

on a variety of subjects relating to the

Austrian supply industry. There was also a

trade fair where, on 58 exhibition stands,

companies from Austria and other European

countries showed the latest technical

products for use in the fields of gas and

water supply.

TRM was present on a joint stand shared

with the Hawle, EWT and Krammer

companies. As well as the successful new

stand design, a mixture of modern and

traditional, what made the event a success

was above all the contacts made by the

members of TRM’s field sales force. “We

had plenty of discussions which pointed

us in the right direction and made some

very promising contacts”, was how Thomas

Schleicher, Head of Sales for Austria,

summed up the more than satisfactory

way the federal conference had gone.

WETEX in Dubai

True to the “tradition” it has established

since it began its business activities in Dubai,

Buderus Pipe Systems FZCO again

showed there at this year’s WETEX, the

most important fair for the water and

waste water industry in the Gulf region.

The economic crisis has had a perceptible

effect even on the Emirates and it was precisely

in times of economic crisis like this

that it was important to show the service

the subsidiary can provide and the proven

products of the cast iron pipes group, and

to put more effort into making personal

contacts, which have traditionally been

very important in the region.

The numbers of visitors, which were up

on those for the same event last year, underlined

the importance of WETEX, which

was held for the eleventh time, from 29 to

1 March, at the Dubai International Convention

and Exhibition Centre under the

patronage of Dubai’s Minister of Finance,

H.H. Sheikh Hamdan Bin Rashid Al Maktoum.

The largest group of visitors were

from the United Arab Emirates, followed

by guests from Oman. There were also a

number of visitors from Bahrain, Iraq, Jordan,

Libya, Saudi Arabia and Yemen.

This year, B.P.S. once again put the emphasis

on solutions to special applications

problems. It was exclusively BLS ® pipes

and fittings that were shown. At a seminar

that accompanied the exhibition attention

was focused on the “Ductile Speciality

Pipes” – fire-extinguishing pipes with BLS ®

joints and BLS ® ZMU pipes – and their areas

of application such as trenchless laying,

sloping pipelines and high pressure

pipelines, etc. “Our work was directed

to certain target groups and it paid off,

because almost 40%

of the visitors to the

stand were contractors

and consultants,

and we had detailed

discussions with them

in which we were able

to give them a clearer

picture of the advantages

of the ductile cast

iron pipe system”, was

the comment from Paul

Jennings, Managing Director

of B.P.S.

Leon Bauer, who has been manager of the office in Dubai

since the end of last year and is also responsible for the

organization of fairs and exhibitions at B.P.S.

WATENVI in Brno

The International Water Management and

Ecological Fair in Brno is one of the biggest

ecological fairs in the whole of Central and

Eastern Europe and the main areas it covers

are water management, waste disposal,

the use and recycling of waste, and environmental

protection. The fair combines

two events which complement one another

– the International Water Management

Exhibition VODOVODY-KANALIZACE

(VOD-KA) and the International Environmental

Fair ENVIBRNO. More than 00

exhibitors from 10 countries were in Brno

in the Czech Republic for the fair from 26

to 28 May 2009 and more than 8500 trade

visitors showed their interest. It is a tradition

for our subsidiary Buderus Litinové

Systémy from Beroun in the Czech Republic

to take part and on a splendid 110 square

metre stand it spotlighted the subject of

“Trenchless Laying”.

WOD-KAN in Bydgoszcz

BGW’s sales and distribution partner in

Poland, Tyco Waterworks, showed a wide

selection of the range of Buderus pipes

and fittings at this year’s WOD-KAN, the

International Fair of Machines and Facilities

for Water Supply and Sewage Systems.

The most important fair of its kind in Poland

was staged from 26 to 28 May 2009

at Bydgoszcz’s new fair and exhibition

centre. Around 8000 visitors underlined

the great interest that there was from the

specialist public attending the fair.

Conference in Algiers

On 29 April 2009, Wogapit, a Franco-Algerian

group of companies, organized a

conference on the subject of sales and

trading relationships with Algerian companies

in the capital Algiers. Invitations had

been sent out to representatives of the

Ministries of the Environment, of Water

and of Agriculture, to representatives of

official bodies such as the German Chamber

of Foreign Trade and the German embassy

and to consultants working for large

construction firms. Representatives of the

press and Algerian television also attended.

Wogapit sells and distributes products

for underground construction on the

North African market and handled a

project with BGW back in June 2008. BLS ®

pipes and fittings were supplied for an irrigation

system in the Algiers region. Since

then the Algerian wholesaler has been interested

in long-term collaboration with

B.P.S. and BGW. To provide some active

assistance in promoting the business interests

of the two sides, Wogapit has instituted

a series of events, and the first of these

on 29 April was very promising. Paul Jennings,

Managing Director of B.P.S., and Peter

Waßmuth, Marketing Director, gave a

presentation highlighting the capabilities of

the cast iron pipes group and the emphasis

it puts on quality and drew attention to the

unique features of the “specialities”, the

BLS ® joint and the ZMU coating. Other

subjects dealt with were the particular

suitability of ductile cast iron pipes for

trenchless laying and their advantages for

high-pressure pipelines. “The event gave

us a marvellous opportunity to present our

products to an influential circle of decision

makers. The Algerian market is important

to us because it is a traditional market for

cast iron pipes. What is more, Algeria has

for some years now been showing steady

growth in its economy, it maintains close

ties with Europe, and it has a great need

for investment in the underground construction

sector” explained Paul Jennings.

“That is why we are looking forward to

further events organized by Wogapit with

great interest.”

Record attendance

at the Site Viewing

Day in Berlin

Buderus Giesserei Wetzlar

GmbH demonstrated the

suitability of ductile cast

iron pipes for trenchless laying

at 10 show sites in the urban

area of Berlin.

The 6th International Pipeline Symposium and Site Viewing Day

achieved record attendance figures. On 28 sites, practical examples

were demonstrated to inform visitors about presentday

methods and techniques for the economical renovation,

repair and replacement of existing water, waste water and gas

pipes and the laying of new ones. The Wasser Berlin exhibition

takes place every three years and these special sight-seeing tours

organized by the Berliner Wasserbetriebe water supply company

have been one of its highlights since 199 . BGW was impressively

represented on 10 of the 12 sites by ductile cast iron drinking

water and waste water pipes. In the words of Lutz Rau, a member

of BGW’s field sale force, “Here in Berlin, where almost every

second pipe is laid using the trenchless technique, we had the

opportunity on the 1st of April not only to demonstrate the installation

of our ductile cast iron pipes by the press-pull, auxiliary

pipe and pipe relining techniques and as newly laid pipes but also

to show our special product solutions such as the ZMU-PLUS

pipe. The response from more than 600 interested visitors to

our sites was unusually good. This was no surprise because the

trenchless installation technique is steadily gaining in importance

and its development has already been considerably more productive

than could have been imagined three decades ago when

the first site in Berlin where the trenchless technique was used

caused a sensation.”

Buderus Open Day

at Tracto-Technik in

Lennestadt

Together with Tracto-Technik,

one of the leading manufacturers

of equipment for

trenchless laying techniques,

Buderus Giesserei Wetzlar

GmbH sent out invitations to an

Open Day held on 4 March.

The main attraction at the event was the practical demonstrations

on Tracto-Technik’s testing grounds in Lennestadt in North Rhine-

Westphalia. More than 70 people attending the event watched

with interest the way in which a DN 100 ductile cast iron pipe

was pulled in with a directional drilling system of the Grundodrill

25 N type. They were also impressed by the demonstration of

the burst lining technique: an old steel pipe was cut open by the

roller-carried knife to allow a Grundoburst 400 G type burst lining

system to pull in the ductile cast iron pipe. To give the attendees

a clearer picture of the technique, an exception was made

and the work was done above ground.

“We invited domestic and foreign sales and distribution partners

and their customers to Lennestadt because in future we want to

push even more strongly for the use of our ductile cast iron pipes

in trenchless laying techniques. The size of the response showed

us how important open days of this kind are, where people can

see the technical possibilities and opportunities with their own

eyes”, says Manfred Hoffmann, Export Sales Manager, “and we

are delighted to have in the Tracto-Technik company a partner

that offers both the HDD directional drilling technique and also

the burst and plough techniques for the trenchless installation of

ductile cast iron pipes and can thus cover the full range of nominal

sizes from DN 80 to DN 1000”. Björn Freimuth, a specialist in

the burst lining technique at Tracto-Technik, is convinced of the

advantages of ductile cast iron pipes but there is another thing

he is eager to praise as well: “The Buderus Manual from 2007

on the trenchless installation of ductile cast iron pipes dealt with

the laying techniques brilliantly and we find it a valuable source

of advice.”


Madrid: German ambassador gives an assurance

of assistance

Today, Spain is Europe’s largest single-country market in the cast

iron pipes field. For BGW and its Spanish sales and distribution

partner Construtec, the potential growth of the water and waste

water industry on the Iberian peninsula is reason enough to show

great commitment in developing the business and intensifying the

efforts to make important contacts. As a result Ulrich Päßler, Executive

Director of BGW, and Francisco Domínguez, CEO of

Construtec, accepted an invitation to a meeting with the German

ambassador in Madrid, Wolf-Ruthart Born, on 25 March 2009.

Together with the ambassador and his economic attaché Thomas

Neisinger, they discussed the opportunities that the cast iron

pipes group has to contribute to the sustainable management of

water resources in Spain. The ambassador gave an assurance of

his full assistance – including with public relations work amongst

other things. He suggested organizing a seminar in the autumn on

the subject of “The future, and sustainable Made in Germany water

management” to which representatives from the water management

sector and parties responsible for the investments in infrastructure

in Spain are to be invited.

From left to right: Wolf-Ruthard Born, German ambassador in Madrid, Ulrich

Päßler, Executive Director of Buderus Giesserei Wetzlar GmbH and Francisco

Domínguez, CEO of Construtec

Of the member states of the EU, Spain faces the greatest problems

with the supply of water. Although there is an adequate supply

of water on the Spanish plateau as a whole, the problem lies

in the very uneven distribution of this water. The very place

where there is a shortage of this resource is in the regions where

the demand is greatest, due to irrigated farming using up-to-date

agricultural techniques. As well as agriculture, which altogether

accounts for the lion’s share of annual water consumption, the

amount of water used by Spanish households is also well above

the European average.

Added to this is the fact that there has been a steady decline in

resources over the past few years. The efficiency of water management

is unsatisfactory and the infrastructure is inadequate or

antiquated. Because of this, programs worth billions of Euros

have now been instituted to allow measures to improve things to

be pushed ahead with.

The HIGHJET ® TDI oxygen process increases

the output of the cupola furnace at TRM

TRM’s cupola furnace went into operation in 1972 with an

hourly output of 12 tonnes of molten iron/h. After the system

was modernized in 1996 it was possible for output to be raised

to 15 tonnes/h. The increase in capacity at GKG, which is also

supplied with molten iron by this furnace, and the rise in output

at TRM made it essential for there to be a further rise in smelting

output. “We decided,” says Max Kloger, chairman of the

board at TRM, “to use the new HIGHJET ® TDI oxygen injection

process that was developed by the Linde Group in 2006.

In this process, a sub-flow of the primary combustion air is extracted

on the injector principle by means of a driving oxygen

nozzle using preset amounts of oxygen and is then mixed in the

driving nozzle and fed into the cupola furnace at velocities from

40 to more than 80 m/s in an enrichment ratio of between 0

and 60%.”

“In earlier trials involving the blowing-in of oxygen through special

lances”, explains Harald Tschenett, Head of Production at

TRM, “we did not achieve satisfactory results. In the HIGHJET ®

TDI process, the small amount of air blast that remains makes

its way into the cupola furnace at 12 to 16 metres a second

through tuyeres of a new type. The advantage in this case is that

the oxygen is not injected as quickly as it was with the lances

and this is kind to the tuyeres. Also, the low speeds of the rising

furnace gases result in a longer dwell time in the shaft of the

furnace and hence in better heat exchange with the material of

the charge. The total amount of air introduced into the furnace

can be considerably reduced, which means a reduction in the

strain on the extraction system – which is always a bottleneck

on the cupola furnace.”

During the shutdown at Christmas 2007/08, the tuyeres on the

cupola furnace were converted and the new process was installed.

The test carried out at the end of the trial run showed a

smelting output of 18.5 tonnes/h for the GKG charge and of 18

tonnes/h for the charge for pipes. Oxygen consumption at this

peak output was 28 Nm³ of oxygen per tonne of molten iron.

“Subsequently, we were able to raise the daily output of our

cupola furnace to up to 400 tonnes and in this way to achieve

the target we had set. Although the foundries were working at

high capacity we did not have any appreciable downtimes” is

how Tschenett sums things up.

In the commemorative year of 2009,

the federal Austrian state of Tyrol,

together with the autonomous provinces

of South Tyrol and Trentino,

is remembering the events of 1809.

In the context of the conflicting demands

of tradition and modernity,

myths and historical facts are to

be seen in their contemporary relevance,

attention is to be focused on

the present, and impetuses are to be

given for future work in the area of

social policy.

“History meets the Future“

200 years after the population of the Tyrol

rose in rebellion under the leadership

of Andreas Hofer, a wide range of events

looking at what happened in 1809 under

the motto “History meets the Future” are

taking place throughout the state in the

current commemorative year. There can

be no question that the historical figure

of Andreas Hofer is of central importance

in this examination of history, myths and

legends.

The man and the myth

Andreas Hofer was a man of his time, a

late 18th century Tyrolean who – before

he took his place on the public stage – attracted

hardly any attention either in the

good or the bad sense. He worked as a

farmer and innkeeper and tried to earn a

little extra as a trader, at which he was not

entirely successful. With the honours bestowed

upon him by the Emperor and the

government, the year 1809 was his time

of greatness but it came to an abrupt end.

The Tyrolean fought for God, Emperor

and fatherland and it was for God, Emperor

and fatherland that Andreas Hofer

laid down his life – his death however

brought almost nothing but misfortune for

his family. It was only with difficulty that

they were able to gain anything solid from

the Emperor to back up his thanks. Peace

and quiet returned to the Tyrol and as yet

the mythologizing of Andreas Hofer was

not a concern. It was only some decades

later that interest in the events of 1809

and in the figure of Hofer as a “hero” began

to revive.

An innkeeper against the troops of Napoleon

1809: Napoleon wants to rule the whole

of Europe. But a Tyrolean innkeeper,

farmer and cattle trader resists and becomes

- though today his claim to the title

is not uncontested – a national hero.

Andreas Hofer – and what he means to the state of Tyrol

The historical context

Revolutionary France was expanding and

while still under the nominal control of

Louis XVI (executed in 179 ) it declared

war on Austria and Prussia in 1792. The

people’s armies of the Revolution soon

proved superior to the standing armies

of Prussia and Austria. By the “Peace of

Basel” of 1795, Prussia left the coalition

against France – Austria fought on until

1797. Hofer took part in the battles against

the French in the years 1796/97 as a member

of the company of musketmen from

the Passeier Valley.

The War of the Second Coalition against

France (1798-1802) was more successful

for France’s opponents, but their successes

were overturned in the War of the

Third Coalition. After its devastating defeat

at the Battle of the Three Emperors

at Austerlitz (1805), Austria concluded the

“Peace of Pressburg”. The Tyrol was now

under Bavarian control and this brought

with it a series of reforms. What baffled

the Tyroleans above all was the interference

in the area of religion, such as the ban

on the midnight service on Christmas Eve,

the abolition of processions and pilgrimages

and the prohibition of peasant festivals

such as the Feast of the Sacred Heart.

However, the final straw was not so much

the religious reforms as the disregarding of

the old Tyrolean constitutional statute relating

to military service and the introduc-

A stainless steel statue of Andreas Hofer dressed in his original

clothes (the Passeier Museum). Hofer was born in Sankt

Leonhard in the Passeier Valley in South Tyrol on 22.11.1767.

His parents died while he was still young and he hired himself

out as an assistant to wine merchants and horse traders

and travelled a lot. At only 22 years of age he took over the

dilapidated Sandhof inn from his stepmother and in 1789 he

married Anna Ladurner, with whom he had six daughters and

a son. As early as the days of Joseph II he represented his

district at the Tyrolean Landtag. Hofer never learnt to read

and write properly.

tion of universal conscription. The sons of

Tyrol had to serve as soldiers for a period

of seven years. The “Landlibell” of Emperor

Maximilian I of 1511 had restricted military

service to defence of the country and

Tyroleans could not be called up for military

service outside Tyrol. What the population

was willing to fight for and its concept

of freedom had already been shaped

by the “Landlibell”. It had strengthened

their self-awareness, had evened out the

differences between the classes and finally,

with the defence against enemies from

outside, had produced a distinct sense of

Tyrolean identity.

In this situation Hofer could not submit in

silence. In 1805, Archduke Johann charged

him with the organization of resistance to


the Bavarians in the Passeier Valley and

Vintschgau. Although the Court in Vienna

and the military were not very happy

about the idea of a national uprising, in

April 1809 rebellion erupted in the “holy

land of Tyrol”, as it is sometimes called.

With his poorly equipped musketmen,

Hofer achieved a first victory over the Bavarian

army at Sterzing. In Innsbruck too

the rebellion was a success.

Emperor Francis assured the rebels that

Vienna wanted permanent unification with

Tyrol. A Bavarian and French army of intervention

was beaten back at the second

battle on the Bergisel near Innsbruck. In

the meantime however, Austria had given

Napoleon an undertaking to withdraw all

forces from Tyrol and Vorarlberg.

Hofer’s followers were thus thrown back

on their own resources. Nevertheless

they entrapped enemy forces in inaccessible

ravines in the country and inflicted

heavy losses on them. At the third Battle

of Bergisel, Hofer just managed to scrape

a victory over the Bavarians and French.

Now began his brief rule from Innsbruck

as Imperial Commandant. He conducted

the business of government from the Hofburg.

The deeply religious and strictly conservative

Hofer was not much liked by the

citizens of the capital of the state of Tyrol

– he imposed regulations relating to dress

for example on the wives of the easy-going

Innsbruckers.

The military defeat of the Austrians at

Wagram (5/6 July 1809) resulted in the

Treaty of Schönbrunn (14 October 1809)

under which Emperor Francis, contrary to

his earlier promises, was forced to cede

Tyrol again to France and Bavaria.

Napoleon then had 56,000 men march in

from different directions. Hofer left Innsbruck.

On 1 November Bavarian troops

stormed the entrenched positions on the

Bergisel. Although some of the skirmishes

ended successfully for the Tyrolean musketmen,

Hofer was forced to flee. The

uprising, which amongst other things had

cost the state around 1000 dead and close

on 2000 buildings destroyed, collapsed at

the end of November. Hofer hid with his

family and his clerk on the Pfandleralm in

the Passeier Valley. He was betrayed however

by his former friends and the French

found him in January 1810. In February

1810 a court martial, acting on Napoleon’s

instructions, sentenced him to death. He

was executed by firing squad on 20 February

1810 in Mantua. In his farewell letter,

he wrote: “Farewell, wretched world!

Death seems to me so easy that my eyes

are not moistened by a tear.”

Andreas Hofer at his execution in Mantua.

The salvo from the French firing squad did

not kill him at the first attempt: he got to

his feet again and is supposed to have said

to the soldiers: “Oh, what bad shots you

are.” The sergeant in charge went over to

Hofer and administered the coup de grace

from very close range.

The Vienna newspapers did not report

the death of Hofer because there was

something more important to announce:

Napoleon I was to marry Marie-Louise,

the daughter of the Austrian Emperor.

The tomb of Andreas

Hofer in the

Court Church in

Innsbruck.

His body was exhumed

in Italy in

182 to be buried in

Innsbruck.

The words of the

Tyrolean national

anthem (written by Julius Mosen in 18 1)

celebrate the death of the national hero.

The melody to which it is set was composed

by Leopold Knebelsberger in

1844.

Customer opinions are important to us!

Customer satisfaction plays an extremely important part in the

success of a company on the market. The more satisfied a customer,

the greater their loyalty to the company and its products.

Customer satisfaction depends on many varied factors. The

smaller the difference between the customer’s expectations and

the degree to which they are felt to be met by the product and

the service given, the more satisfied the customer is. Ideally, the

customer’s expectations are exceeded. Surveys are used as a tool

for establishing the degree of customer satisfaction. In November

2008, in collaboration with three regional market research institutes,

we surveyed a random sample of our customers including

local authorities, planners and operators of snow-making installations

in Germany, Austria and Switzerland.

It turned out that our customers take a very positive view of our

Random sampling errors, i.e. confidence intervals, not given for the results

products and their high quality and of the expertise that our employees

have in applications engineering, even in comparison with

the competition. At the same time, the results also showed that

there is a need for improvement in some areas. This is where

there has to be some further development if there is going to be

any sustained gain in customer satisfaction.

There is an increase, almost a steady one indeed, in the importance

attached to the visual state of our products at the time of

delivery. We want to improve the state of our products on delivery

(the lining and outer coating), in order to give the customer a feeling

of confidence about problem-free laying and long life.

► One of our very special concerns is to give our customers a

boost with even greater flexibility and shorter and precises delivery

times.

► We want to supply our customers with upto-date

information and better documentation.

With this in mind, we shall be devoting considerable

effort over the next few months to the

following subjects: the internet, catalogues, data

sheets and on-line catalogues.

The view that customers take of the long life

and economy of our products is not, as yet, the

same as the view we ourselves take. We want to

ensure that our customers are better informed

about these points and to convince them of the

long life and extraordinary economy of our products.

Something new for snow-making systems

In the future too we want to cast a critical eye

on ourselves regularly and to see ourselves as

our customers see us, so that we shall continue

to be able to find out what desires and suggestions

our customers have and to satisfy them. We

have therefore decided to repeat the surveys at

specified intervals.

Under the overall control of the specialists from Hall and in collaboration

with their colleagues from Wetzlar, Beroun, France

and Italy, new information documents have been produced

for the field of snow-making systems.

As well as the product folder entitled “Reliable Snow”,

which is available in German, English, Italian, Czech

and French, folders dealing with reference installations

and a technical catalogue have been produced.

These documents were presented to a wide audience

for the first time at this year’s Interalpin exhibition and

were very well received.

To give customers what they want and ensure that marketing

documents are informative and expressive, work is currently

being done on product and project folders for the field of

“Ductile Cast Iron Pipes for Turbine Pipelines”.


The FGR elects a new executive board

On 1 March 2009, the Fachgemeinschaft Guss-Rohrsysteme e.V.

(FGR – Trade Association for Cast Iron Pipe Systems) elected its

new executive board as required by its articles of association. All

the member companies took part in the election.

Ulrich Päßler (on the left), Executive Director of Buderus

Giesserei Wetzlar GmbH, was elected to the new executive

board and Ulrich Hezel (on the right), CEO of Düker GmbH &

Co KGaA, was elected to the deputy executive board.

The trade association is a technical and scientific association that

brings together companies, only German ones so far, that produce

pipes, fittings and accessories made of ductile cast iron.

The FGR originated from the Deutscher Gießerei Verband or

Germany Foundry Association. It has been active in its present

form since 195 .

Its principal tasks include:

To make known the technical and scientific advantages of the

ductile cast iron pipe system for carrying drinking water and

waste water and for all the modes and methods of installation.

To promote and encourage the use of ductile cast iron pipes in

the context of planning, installation and operation.

To collaborate on national, European and international standardization

relating to all matters that affect the use of ductile

cast iron pipes.

For the future, the FGR will be endeavoring to take its place

as a European association representing the interests of the cast

iron pipe industry including those of manufacturers of cast iron

valves. With an improved budget it will be able to become altogether

more targeted and powerful and will be better able to

achieve its goals. Päßler and Hezel are agreed that in the long

term the only effective way of continuing to build up the FGR

and to consolidate its promotional activities for ductile cast iron

as a material in a sustainable way is to expand its activities onto

the European market.

Andreas Schreitel takes over as manager

of TRM‘s centrifugal pipe casting

foundry

On 1 February 2009, Andreas

Schreitel took over as the manager

of TRM‘s centrifugal pipe casting

foundry in Hall in Tyrol. He was

born in the Tyrol and began work

at TRM in July 2001 as a machine

operator and from the very beginning

he stood out for his dedicated

application to the job in hand and

his strong commitment. Although

his previous training had been

commercial, this soon allowed him

to gain a footing in the production

area. He took numerous training and advanced training courses

(including as a work study engineer) and as a result was appointed

a quality officer in the production department in January 2005.

As time went on, he then took on the very demanding role of

coordinator in our TGVS scheme for employee’s suggestions for

improvement and he has now been appointed the manager of

the centrifugal pipe casting foundry. In this function, his attention

will now be focused above all on getting the new centrifugal pipe

casting machine commissioned as quickly and as successfully as

possible, a task in which – for our own sakes as well as his - we

wish him every success. After more than 41 years of service to

the company, 0 of which he spent in the centrifugal pipe casting

foundry, Franz Rühr, the previous manager of the foundry, took

his well-deserved retirement on 1 May 2009. We would like to

take this opportunity of again extending to him our very grateful

thanks for the exceptionally dedicated work he did and his great

devotion to the company.

TRM introduces a database for the STOP

sign suggestions scheme

In collaboration with TRM, the new

database developed by Mohr-Tools for

the STOP sign suggestions scheme has

been adapted to suit our special requirements.

The database, by means of which all the information

and analyses required can be called up “at the press of a button”

was introduced in January 2009. The administration, processing

and monitoring of the STOP sign suggestions can now be handled

more easily and with considerably greater clarity. What is more,

the people submitting STOP sign suggestions will have an opportunity

of following the progress of their suggestions in a more

satisfactory way. There are also plans for access to be organized

for BGW so that a comprehensive pool of ideas can be created.

These are some of the things the database can do:

Automatic calculation of prizes with details of the calculable

benefit

Administration of users including granting of rights

Administration of the sponsorships

Coverage of several companies

A vast variety of analyses (cost/benefit plots, number of STOP

sign suggestions in a plot, cockpits)

Ramma Damma cleaning and

litter-clearing day in Hall with

a record attendance

TRM’s Ramma Damma cleaning and litter-clearing

day is already an established

tradition and was held again on 6 June, this

time with a record attendance. More than

100 TRM employees turned up “armed”

with cleaning utensils and painting gear to

freshen up and thoroughly clean parts of the

factory site.

In addition, 16 colleagues from BGW accepted

the invitation to the 2009 Ramma

Damma, travelling from Wetzlar in groups

and giving an enthusiastic helping hand to

ensure that the aims set for the day were

achieved. They were also given a tour of

the works to get to know the sister factory

in the Tyrol better and to enable them to

make or strengthen contacts outside their

home site. “We were delighted to receive

this invitation and found the relaxed mood

and the cordial welcome we received absolutely

super”, said Melanie Turek, assistant

to the executive management at Wetzlar. As

always, the high point came when the work

was done in the form of a companionable

get-together with plenty of food and drink,

during which there was a spontaneous announcement

from quite a few of the Hall

employees of how they would be interested

in giving a helping hand to their colleagues

from Wetzlar at a similar day of action.
