Progress by Tradition
BUTTING was founded in 1777 as a
coppersmith’s by the ancestors of the
current owner, Hermann Butting. In 1945,
the family-owned company moved its
headquarters to Knesebeck and started
producing soldered, and later welded,
copper pipes. In the late 1950s, stainless
steel gradually replaced copper as the
main raw material for BUTTING products.
The company has been in family ownership
for seven generations, and its staff
of more than 1,400 now handle more
than 40,000 t of stainless steel of various
grades every year.
A diverse Range of
Products
The production of high-quality longitudinally
welded pipes made from stainless
steel – in both standard and special sizes –
has been the focal point of our business
since the development of stainless steels.
Few companies in Europe can point to
such longstanding experience and diversity
as BUTTING in the production of

of longitudinally welded pipes,
BUTTING manufactures and supplies a
wide range of piping components. Our
customers can cover all their pipework
and component needs with us – from
one source. The combination of pipes and
fittings of proven BUTTING quality into
special ready to install piping components

capacities also guarantees you optimum
cost-effectiveness and reliability. Since
BUTTING was founded, the construction
and assembly of vessels has been an established
part of our wide range of services.
High-Quality prefabricated
Products
The use of stainless steel pipes in many
sectors of industry has for decades been
“state-of-the-art”. BUTTING took an
early decision to prefabricate pipes and
vessels according to models or pipe-plans
to the greatest possible extent. There
were strong arguments in favour of assembly
taking place in the plant, such as
improved product quality and increased
potential for cost-savings. In countless
projects all over the world, companies put
their money on the long-lasting reliability
of prefabricated BUTTING pipe systems.

Close to Customers
worldwide
For seven generations, the name BUTTING
has stood for quality and flexibility. Today,
more than 1,400 employees in the medium-sized
family-owned company process
over 40,000 t of stainless steel every year.
Pipes and pipework components are now
produced in a number of production halls
on our site in Knesebeck, which occupies
over 395,000m². The history of BUTTING
is one of continuous healthy growth, with
its roots in a farsighted entrepreneurial
spirit. It was this thinking that prompted
Dr Hannshermann Butting to establish
an affiliated company in Schwedt / Oder
following German reunification in 1991.
Today, BUTTING Schwedt is our expert
unit for vessel and pipework construction
and for international installations.
Since 2004, BUTTING has been present
in China. We have a production facility
in Jiading on the outskirts of Shanghai,
producing pipes and customized pieces for
the Chinese market. Our aim is to inspire
our customers. For some services and / or
products this requires geographical proximity
to our customers. For the same reason,
we decided to establish branches in
Canada and in Brazil. We want to provide
our customers with our many years of
experience in processing stainless steels
more quickly and directly.
BUTTING in Knesebeck: “We provide the most up-to-date and sophisticated
12-metre pipe production facilities of the world for pipes made from plate!”

Continuous manufacturing of longitudinally
welded pipes is economically
advantageous
The continuous, fully-automated production
process is the most technically
sophisticated and economical process
for manufacturing longitudinally welded
pipes and profiles. In the process, cold
forming, welding, heat treatment, calibration
and non-destructive testing take
place online, i. e. in a carefully calcunology
and our quality assurance are in
evidence every day as we satisfy requirements
from all kinds of industry.
BUTTING basically has two different production
processes available for manufacturing
pipes:

lated work sequence. On several production
lines, BUTTING can produce pipes
from coil with diameters from 20 mm
to 762 mm and wall thicknesses up to
16 mm. The normal random length is 6 or
12 m. However, shorter fixed lengths or
lengths up to a maximum of 18 m can be
manufactured in the line, in a number of
sizes without circumferential weld.
Longitudinally welded pipes with wall
thicknesses up to 70 mm and a maximum
outside diameter of 3,000 mm can be
produced from individual plates on our
state-of-the-art production facilities, with
no outsourcing of individual production
steps, in standard lengths up to 24 m.
18 m pipes are manufactured to order, e. g. for a sewage plant

Wide Selection in Store
Since the company moved to Knesebeck in
Lower Saxony in 1945, a large number of
modern production halls have been constructed.
In an outdoor area covering over
20,000 m², BUTTING keeps permanent
stocks of around 3,000 t of stainless steel
pipes in over 140 sizes, from NB 15 to
NB 600, e. g.
• pipes in 1.4541 / 1.4571 according to
DIN EN 10217-7
• pipes in 1.4462 according to
ASTM A928 / DIN EN 10217-7
• pipes in 1.4539 according to
ASTM A312 / DIN EN 10217-7
• pipes in TP 304L / TP 316L according
to ASTM A312 or ASTM A358
• stainless steel pipes for the food
industry according to DIN 11850
• piggable stainless steel pipes in
1.4307 / 1.4404 according to DIN 2430‐1
Welding Technologies for
all Requirements
BUTTING has both the processing facilities
as well as qualified and certified staff to
carry out all the usual welding processes.
BUTTING can carry out all the usual
welding processes in pipe manufacture
from coil. The TIG process has proved its
quality by producing reliable and costeffective
results through the years. In
the last decade, the laser beam welding
process has gained increasingly in importance.
Laser welding allows relatively high welding
speeds, and also offers metallurgical
advantages. The seam and the heataffected
zone are formed very narrowly.
This development decisively improves the
quality of the welded joint. With the laser
welding procedure, BUTTING can satisfy

For welding thick-walled plates, including
those of high alloy materials, we are one
of the few manufacturers in Europe to
use not only the submerged arc welding
method, but also the efficient electron
beam welding process, with its excellent
performance and high controllability and
reproducibility of the weld seam.

Elbows and Fittings
Along with longitudinally welded pipes,
BUTTING also produces and supplies pipe
fittings made to project requirements
from all the stainless steel materials that
we handle. For this, the company maintains
diverse stocks of selected fittings.
On an order-by-order basis, these fittings
are also produced to particular dimensions
and from special materials for a variety of
different applications.
Elbows
Depending on the outside diameter, we
produce pipe elbows free of folds from
longitudinally welded BUTTING pipes to
customers’ requirements by means of a
bending process using rollers, cylinders
or mandrels or from two halves made of
plate. The various production methods
enable pipe elbows to be manufactured
according to DIN 2605, type 3 or 5, or
with even bigger radii – or on request
with a tangent without a circumferential
weld. Three-dimensional multiple
bends with graded radii can be made in
accordance with customers’ isometric
drawings.
Tees and Branches
Tees and branches are manufactured from
high-quality BUTTING piping. The tolerances,
construction types and testing of
butt-welded or saddle-shaped tees can
be chosen according to DIN 2615 / 2609
or ASTM standards, or on the basis of the
customer’s specifications.
The branches are produced as saddles, as
extruded or butt-welded branches.
Prefabricated piping components:

Collars
BUTTING manufactures slip-on collars
and welding neck collars without bevels,
similar to DIN 2642, using semi-automatic
presses. Large quantities of these fittings
up to NB 400 in size are produced continuously
from coils, or in individual production,
from plates. Cold formed angles
from plate are used to make larger welded
collars up to NB 1,000.
To match our stock of standard pipes,
we can provide you with a wide range of
welded and slip-on collars from stock.
Reducers
Depending on the size, BUTTING produces
reducers both from longitudinally
welded pipe and plate. The customer can
specify an eccentric or concentric (conical)
shape – also with cylindrical ends. Depending
on requirements, the tolerances
and testing for these fittings are defined
according to DIN 2609, ASTM A403 or the
customer’s specifications.
Flanges
Flanges are wrought or produced from
plate and machined all round. Flanges are
constructed according to DIN or ASTM
B16.5 with the corresponding pressure
ratings.

Special Components
BUTTING produces specials and piping
components, ready for installation, e. g.
flare tips, non-standard fittings or parts
with special geometries and contours
on special demand. On special bending
machines, integrated elbows can be
made, as well as branches in the form of
extrusions. Single random pipe lengths
can be made into 24 m lengths by welding.
Circumferential welding of pipe
fittings can also be carried out.
Within an extensive value added chain,
first class fabrication is guaranteed by the
use of high quality semi-finished products
from BUTTING, a high degree of automation
and skilled and qualified staff, even in
the case of very complex components.
Prefabrication with surface treatment and pickling at the plant especially improves
the corrosion resistance of stainless steels

Prefabrication with longstanding
Experience
Prefabrication of pipelines and vessels
is an assembly moved forward into the
producer’s workshops. The lesser welds to
be made and pickled on site, the better is
the quality of the weld and surface which
also means a reduction of maintenance
and repair costs.
The clear advantages of prefabrication at
BUTTING cannot be denied:
• reduction of welds on site, e. g. by integrated
bends instead of welded-in
elbows, or the use of branches instead
of welded-in tees
• improved product quality and less
testing due to the use of state of the
art and various production facilities at
BUTTING (certified reproducibility)
• less space needed on site
Prefabrication at BUTTING enables efficient,
integrated planning for production sites.
Prefabricated pipe parts guarantee high
quality, fast installation and lower costs.
Prefabricated piping components for
an efficient assembly
Precise CAD planning assists the
quality of prefabrication
is optimized. This means adjustments can
easily be made to isometric drawings on
a project-by-project basis and accurate
billing can be carried out when assembly
is complete.
To summarize:
In addition to a much higher product
quality, the extensive cost-cutting
potential in the installation, maintenance
and service of pipe systems and vessels
has convinced many of our customers of
the advantages of prefabrication.

Longstanding
Experience
Ever since the introduction of stainless
steels, BUTTING has been using these materials
in its production and has gathered
extensive experience in the forming,
welding and heat treatment.
In 1979, BUTTING produced longitudinally
welded pipes in duplex for an onshore
project of NAM. This was the first time a
duplex pipe was made in the world. For
more than 20 years we have been supplying
pipes in nickel alloys to the chemical
industry, offshore installations and shipbuilding
industry.
Variety of Materials
BUTTING uses a big variety of high performance
materials for specific and corrosive
environments in different industrial
sectors. The fabrication of innovative
materials for individual solutions is a daily
challenge to our metallurgists, welding
engineers and production staff.
Optimizing Material
Properties
In the case of special requirements, e. g.
corrosion resistance, formability, strength
or structure of the material, it is possible
for BUTTING to improve the characteristics
of the parent metal and longitudinal
weld by selective heat treatment.
For this purpose, the following processes
are used: solution annealing, stabilizing
annealing, stress relieve annealing, recrystallization
annealing and soft annealing.
Preventing Claims
During the fabrication and use of pipelines,
vessels and piping components in
corrosion resisting stainless steels and
special alloys, it is crucial to avoid damages
by corrosion. In order to achieve
this goal, BUTTING uses its extensive
experience and knowledge regarding
material science, process engineering,
welding and forming technology.

S u r f a c e t r e at m e n t
Surface finishing – in this case cleaning by means of pickling – is required to
ensure finished components to be corrosion-resistant
The Surface
Condition counts
After their fabrication, high alloy special
steels must have the same corrosion resistance
– especially when used as welded
joints – as the parent metal. It is therefore
very important to provide a bright metallic
surface, i. e. it must be completely free
from tinting, scale and ferrite contaminations.
Care right along the
Production Line
The value added processes at BUTTING
take into account the material properties
of corrosion-resistant steels. Prior
to the start of production, the materials
are stored properly. During production,
it is ensured that the starting material is
processed using corrosion-resistant steel
tools only.
Due to the large number of high alloy special
steels and their different requirements
in the process industry, BUTTING uses
various customized methods for surface
treatment.
Optimum Pickling
Conditions
Pipes and piping components always
undergo chemical full-body pickling at
BUTTING. This process ensures corrosion
resistance after the forming, welding
and annealing processes. Full-body
pickling ensures cleanliness of the surfaces
and formation of the passive layer
which is indispensable for protection
against corrosion, even at inaccessible
locations of the prefabricated piping
components. BUTTING has a number of
20.0 × 4.0 × 2.0 m pickling baths, plus
16 pipe pickling baths up to 27 m long.
At both Knesebeck and Schwedt, our
products can also be treated by spray

pickling if required. In addition to chemical
surface treatment, customer-specific
requirements are met by means of mechanical
processes, in particular grinding
inside and outside surfaces. BUTTING
has radial grinding equipment for outside
surfaces. Pipes with dimensions from
NB 20 to NB 350 can be ground with grit
from 180 up to 400, under optimum conditions.
Both radial and axial grinding machines
are available for grinding the inside
surfaces. As a further option, products
can be treated using shot peening with
various types of grit to satisfy optical requirements.
Prefabricated piping component prior to full-body pickling
Where pipe assemblies are concerned,
BUTTING avoids using mixed constructions
at all times. Otherwise, there could
be a risk of contact corrosion, if, for example,
pipe clamps or round steel clamps,
screws and sleeves made of unalloyed
structural steel came into contact with
stainless steel.

Your Partner with
Tradition
Since BUTTING was founded, the partnership
with companies in the paper and pulp
industry has been an important component
of our corporate identity. Numerous
projects in which we have been involved
have been implemented worldwide right
up to the present day.
Experience pays off
Decades of cooperation link the UPM
(formerly Haindl) paper manufacturer
and BUTTING. As early as 1961, BUTTING
took over the pipe installation for PM III in
Schongau. In 1990, we received the order
to lay about 70 t of stainless steel pipes
and around 35 t of pipe fixings for the
reconstruction of EPM 10 in Walsum. After
only 10 weeks – 5 of them pure assembly
time – the paper machine was able to go
back into production again.
Variety from Stainless Steel
BUTTING received one of the largest
installation orders in company history
from the paper and pulp industry from
Palm, for the world’s biggest cardboard
factory in Wörth. 60,000 m of stainless
steel pipes, 100 vessels and 400 t of fixings
were prefabricated, supplied and
installed.

of 4,550 pipes. The order also represented
a new scale of logistical challenge. 392 containers
with 1,500 t of stainless steel pipe
material, 500 t of carbon steel pipe material
and 650 t of fixing material had to be
supplied by sea from Hamburg to Uruguay.
Coping with many Demands
Very recently we were able to demonstrate
our expertise in the paper and
pulp industry for an expansion of production
at the HANS KOLB paper plant in
Kaufbeuren. Here, BUTTING Anlagenbau
was entrusted with the manufacture and
installation of vessels and pipelines for
a corrugated paper-making machine. In
all, we supplied and installed 21 vessels
(vats and pulpers) with a total weight of
37 t. Thanks to the high degree of prefabrication,
the number of staff required
Delivery and assembly of vessels
(vats and pulper) as well as prefabricated
linepipes for a paper machine
on the construction site was small – only
around 30 fitters were needed on site.
Very soon, they were also responsible for
the installation of 7,000 m of pipes with
a nominal bore of NB 15 up to NB 400. In
addition, we installed around 30 t of steel
for mounting brackets and 7.5 t of steel
constructions for operating platforms,
staircases and railings.
Our “one-stop service” also includes
services after the project has been completed:
for this reason we have installed
permanent on site BUTTING teams in
various factories, who are responsible
for maintenance and repairs and for any
pipeline rebuilds.

Competence in
Processing
Flanged well pipes
For decades, BUTTING has supplied the
drilling and well-building industry with
pipes and prefabricated components
having a high level of operational safety
and corrosion resistance. Customized
special production, extensive experience
and material-specific expertise make us a
competent supplier of riser pipes, filters,
flanged and threaded pipes as well as
sealing systems (seal packers) and well
heads.
Water for the Desert
For the “Great Man-Made River Project”
in Libya, the world’s largest ever project
to obtain drinking water in the desert,
BUTTING supplied pipes and piping components
with a total weight of 3,000 t.
Our experience helped us to produce
18 5/8" (473.1 × 11.05 mm) and 10 3/4"
(273.1 × 8.9 mm) casings including API
threads and double sockets.

Well Heads in special
Materials
BUTTING regularly receives interesting
orders from our customers all over the
world. For example, we were given orders
for a number of riser pipes and well heads
of particularly impressive dimensions. The
production of these components, each
weighing 1 t, with an outside diameter of
Well pipes in use in Libya
508 × 9.53 mm for the pipe and an overall
dimension of 3,155 × 1,000 mm, posed a
particular challenge because of the tight
tolerances of form and position.
Prefabricated Components
Our wide range of experience and expertise
in the field of prefabrication was
something we were again able to demonstrate
a short time ago: in equipping
a drilling platform with filter screens, half
pipes, riser pipes and well heads made
from superduplex.
All the components supplied by BUTTING
are in use on the drilling platform as part
of a fire extinguisher system. Pumps at
the bottom of the sea suck in salt water,
and riser pipes and the connected well
head bring it up to the platform, so that
there is enough water available to put out
any fire there.
The pumps are fitted into the filter screens,
also manufactured by BUTTING, and above
them are placed two of the BUTTING half
pipes. The filter is intended to prevent
impurities in the water from being sucked
into the pump, which then guarantees
that the system will function securely on
a lasting basis.
High Quality Requirements
The filters and half pipes produced according
to NORSOK standards required high
standards of welding and processing
and were subjected to detailed testings
(dimensional checks, dye-penetrant testings
etc.) at BUTTING.
Individual specials, extensive experience
and material-specific expertise make us a
reliable supplier of risers, filters, flanged
and threaded pipes as well as sealing
systems and well heads – we would be
delighted to advise you too on how to
implement your ambitious project.

Assembly of pipelines in the Netherlands
For more than 25 years, companies in
the water and waste water management
sector have backed BUTTING – because
of the durable and reliable quality of
our pipe systems. Waterworks and sewage
plants in Germany, Switzerland, the
Netherlands and Greece, indeed as far
away as Russia and China are equipped
with our pipes.
The up to then largest waste water treatment
plant in Europe was built on the
coast at Piraeus for the 2004 Olympic
Games. BUTTING was awarded the contract
for producing the required pipes and
piping components made of 1.4571, i. e.
TP 316L for this plant, with a total weight
of around 400 t. The approximately
13,500 m of pipes in sizes from NB 50 up
to NB 1,400 were produced in wall thicknesses
from 2.0 to 8.0 mm.
A total of 96 aeration latices were
prefabricated for the installation in a

How the BUTTING Group
works together
With its contribution to the construction
of the waste water treatment plant in
Zhapu City in China, our family-owned
company faced a new challenge. For this
project, BUTTING assumed responsibility
for the supply of materials and the prefabrication
of the pipes in Knesebeck.
Following delivery in China, our affiliated
company in Shanghai, BUTTING China,
handled the installation on-site. This division
of labour, and the high-quality work
at both locations, brought significant synergy
effects for our customer.

100 % Factory Prefabrication
For the construction of the Amsterdam
West biological waste water treatment
plant, BUTTING was already involved
from the planning and construction phase,
and was given the order to supply the
materials and to prefabricate the linepipes.
The customer for this project, covering
approx. 200 t of pipes, specified 100 %
factory prefabrication of the main air
duct and the circular tanks. 8,185 m of
NB 80 aeration pipes were provided with
22,600 laser-cut holes (diameter 5.0 mm)
and the associated weld studs to attach
the aerator plates, and then joined to the
air distributor pipes with circumferential
welds.
High-Quality specially
shaped Parts
For a waste water treatment plant in
Poland we were given the order to manufacture
96 aeration lattices. Our scope
of delivery consisted of a large number
of pipe parts manufactured according to
special customer drawings. We processed
a total amount 350 t of material with the
nominal bores of 80, 100 and 250. The
components – mainly made from 1.4571,
i. e. TP 316L – were fabricated in more
than 5,000 man-hours. For the necessary
extrusions as well as for the required
laser cuttings and drill holes, we used
the numerous production facilities of
BUTTING’s laser centre.

How to get drinking
Water – with our
Help
We have been supplying pipes, fittings
and components in highly corrosion-resistant
materials for more than 20 years to
plants which obtain drinking water from
brackish water or sea water. From Israel,
Kuwait and Qatar to Saudi Arabia and the
United Arab Emirates, our products are in
use for this purpose.
Special Alloys for special
Demands
In 2003, the at that time newly developed
material, superduplex (UNS S32750)
was chosen for the first large-scale desalination
plant in Asia, to meet the high
anti-corrosion requirements in this area.
BUTTING received the order to manufacture
more than 110 t of pipes with outside
diameters from 762.0 to 914.0 mm from
individual steel plates.
Large Wall Thicknesses for
high Pressure Levels
For one of the largest sea water desalination
plants in the world, BUTTING supplied
more than 57 t of pipes ranging from 4" to
14", in the UNS S31254 material. Of these,
for example, we produced 1,000 m of
168.3 × 7.11 mm pipe. We also worked
more than 162 t of superduplex plates
into pipes of various sizes with large wall
thicknesses.
20 manifolds with 600 on-welded
branches for a plant in the Middle East
Pressure Exchanger with
tightest Tolerances
We are happy to work with our partners
in this field to create project-specific
solutions. For use in reverse osmosis, one
customer developed a system which substantially
reduces energy costs through
hydraulic force transfer. The core of this
system is a pressure exchanger made from
BUTTING pipes. The 273 × 12 × 8,900 mm
pressure exchanger pipes that we produced
for this were subject to very tight
tolerances.
Everything from a single
Source
For a desalination plant in Fujairah in the
United Arab Emirates, the first step was
Pressure exchanger pipe in 1.4539

to produce pipes of TP 316L, duplex and
superduplex materials weighing a total of
70 t. In the course of the project, BUTTING
was also entrusted with manufacturing
complete pipe parts to be fitted on site.
For this reason 80 % of the superduplex
pipes stayed in our plant for further processing.
Supplemented with parts supplied
by the customer, a highly qualified
team produced a number of pipework
components, along with 20 manifolds and
a total of 600 on-welded branches, while
complying with the strictest measuring
tolerances and welding parameters.
Prefabricated Giants
BUTTING received an order from the
Emirate of Qatar to produce spools as
suction and conveyor pipes for sea water.
To cope with the extreme conditions onsite,
the material UNS S32750 was laid
down in the specification. Production took
place with outside diameters of NB 600
(24"), NB 700 (28") and NB 2,200 (88").
These unusually large dimensions meant
that in this project we had to overcome a
large number of special challenges – both
at the planning stage and during manufacturing
and pressure testing, and not
least in packaging and shipment.

Central pipe in a nickel-based alloy for spray level of the world’s largest flue
gas scrubber in Canada
Progress in all Areas
For more than 30 years, BUTTING has
been manufacturing pipes, piping components,
vessels and specially shaped parts
for environmental and energy technology.
For example, highly corrosion-resistant
materials such as duplex, superaustenite,
superduplex, titanium or nickel-based
alloys have been processed for flue gas
desulphurization plants – materials where
expert handling is necessary in forming
and joining.
The Energy Technology of
the Future
BUTTING’s global activities in many sectors
enabled us to win an order from
the largest Canadian oil sand company,
Syncrude Ltd., to supply the “internals”
for what is currently the largest flue gas
scrubber (flue gas desulphurization absorber)
in the world, with a diameter of
nearly 21 m and a height of 95 m. The
pipework systems needed for the scrubbing
process, with their fixings and a
maintenance platform, were produced by
BUTTING. The order included the creation
of isometric drawings and linepipes with a
total weight of approx. 180 t of the nickelbased
alloys 2.4605 (alloy 59) and 2.4819
(alloy C276).
Piping component for power engineering
For BUTTING this order represented a
challenge in many ways. Never before in
the company’s history had this amount of
nickel-based materials been used for processing
in a single project. The round and
rectangular pipes, branches, reducers etc.
made from steel plates were prefabricated
to systems ready for installation.
In addition, the specified tolerances presented
very serious challenges, in both a
welding and a manufacturing sense. For
instance, no deviations from the straight
larger than 1 mm / m were acceptable.

Components for nuclear
Installations
To manufacture components for the
energy industry, especially for nuclear
plants, requires quality work of the
highest degree, able to be reproduced
again and again. This is essential for the
safe functioning of plants which have
risks attached to them, and it creates confidence
among operators and the public.
Since 1974 BUTTING has been producing
longitudinal welded pipes, shaped
Individual modules are welded
parts and prefabricated pipes for nuclear
installations. This was why we received
an order to supply pipes for a new power
station in Finland.
Special Containers

BUTTING has also specialized in the
manufacture of various containers for
the energy sector, and set up the necessary
capacity. Depending on the purpose,
special containers are produced for fuel
Single canisters for containers in

elements from different types of reactors.
Depending on the specific project, the
individual quality of material for processing
is selected from a wide range, such
as boron-alloyed stainless steels, copper
or aluminium. That way for example,
complete modules are created after cutting
steel plates and preparing the weld
edge by milling and welding, using laser
or electron beam welding. Then they are
welded together to make a container in
a precisely defined and specified position
relative to one another. Tightly monitored
tolerances have to be maintained by experienced
employees.
The cleanliness of the individual components,
modules and the entire container
is crucial for this area. BUTTING implements
the highest cleanliness standards in
line with the customer specification and
maintains them throughout all the work
processes. BUTTING fulfils the high expectations
which our customers have of our
products by our deep understanding of
the world of metallurgy, and by developing
reliable process engineering.

Welded Profile Pipes
Flare tips for power engineering and environmental technology with highest
requirements to welding technology
In addition to the demanding vessel construction,
BUTTING manufactures square
pipes to the tightest tolerances for compact
stores, and special shaped parts
for the power station sector. We have
installed modern laser welding equipment
for this purpose, with which steel plates
which have previously been precisely cut
and milled are corner welded.
The laser technology reduces the warming
at the edge of the weld through an appropriately
high welding speed. In addition to
the advantages in metallurgy terms, this
almost completely excludes any possibility
of the material being distorted by heat
tension. In this way, for example, BUTTING
produced square pipes with an inside diameter
of 222 × 222 mm+ 0/− 1 mm and a
wall thickness of 2.7 mm with a permitted
maximum measurement deviation of
1.5 mm for the 5 m pipe.
A wide Range of environmental
Technology
Since the beginning of the 1990s, an
extra product segment has been added to
BUTTING’s supply programme: flare tips.
In chemical plants, refineries and LNG
plants, surplus gases are burned in an
environmentally-friendly manner by using
flare tips. BUTTING uses a combination of
craftsmanship skills and modern production
equipment to manufacture ready-toinstall
flare tips.
Depending on the composition of the
waste gases and the specific purpose, different
versions may be used, made from
various heat-resistant materials, such as
1.4876, 1.4828 or 1.4841, all produced by
BUTTING.

industry with a large number of special
pipe options for onshore / offshore as well
as sub-sea projects.
Up to now, we have supplied renowned
customers worldwide with products running
to a total weight of over 130,000 t –
including those from special materials.
In addition to the production of conduit
pipes, flow-lines, risers and pipes for
topsides and LNG projects, we have in
recent years expanded our competence
and capacities in the prefabrication for
this sector.
Cross-Sector Experience
Our long manufacturing experience made
us a competent supplier for the Snøhvit
project in Norway.
For the sub-contractors SFF / Norway and
Aker Stord / Norway, BUTTING manufactured
a total pipe tonnage of around
2,000 t. Approximately 2,600 m of pipes in
1,016 × 12.7 mm size were supplied, made
from TP 316L material. About 1,600 m
of the overall amount we welded with
circumferential welds to lengths of up to
24 m, some provided with elbows and
prefabricated into so-called “spools” for
the construction site on Melkøya. The
quality of our products, on-time delivery
and reliability of performance during projects
were described by the customers as
exemplary.
Riser Pipes for Opening Up
the Deep Sea
Some time ago, BUTTING was awarded a
major contract from the oil and gas sector,
followed by a new type of prefabrication
order: Stolt Offshore Services SA / F gave
us an order for the production of pipes for
the ERHA project. As part of this project,
an oil-field was developed off the coast
of Nigeria, to produce 150,000 barrels of
oil a day from a depth of around 1,200 m
below sea level.
2,000 t of pipes among others in size 1,016 × 12.7 mm and spools for the

By the mid-1990s, BUTTING had an order
from Bergens Rørhandel in Norway for the
production of lateral tees. We designed
the isometric drawings for the manifolds
for the Troll Onshore project phase 1 in 6"
and 18" sizes.
BUTTING supplied duplex riser pipes for
Statoil’s Sleipner West project. We also
took on the pre-welding of these 20" riser
pipes with riser-anchor flanges.
19

o i l a n d g a s i n d u s t r y

The order included the production of
1,428 m of longitudinally welded steel catenary
riser (SCR) pipes made of rollbonded
plates in the API 5L-X65 / alloy 825
materials combination.
The pipes, in sizes ranging from
168.3 × (15.9 + 3.0) mm and
273.1 × (20.6 + 3.0) mm were made from
individual steel plates in 6-m lengths during
pipe manufacturing from plate.
Tolerances as a Quality
Feature
Since the ERHA field is in very deep water
and the tightest possible fit of the catenary
risers was required, the tightest
demands on tolerance and quality were
requested. For this reason the absolute
maximum deviation of the inside diameter
in the pipe-ends area from the nominal inside
diameter was set at ± 0.4 mm.
Progress from Experience
In earlier projects, BUTTING had already
demonstrated its skills in forming and
joining roll-bonded steel plates, in the
Bonga project, for example. These successful
deliveries to the oil and gas sector led
Prefabricated piping component for a refinery
Stolt Offshore to give BUTTING an additional
order for circumferential welded
pipes for the ERHA project.
The task was to manufacture prefabricated
pipe parts using our own pipes and
also parts provided by the customer, such
as flexible joints or j-lay collars. A total of
230 circumferential welds were performed
by qualified staff. From bevelling the pipe
ends through tack-welding and welding
to treating the surfaces, quality assurance
checks, acceptance and packaging,
the entire production process took place
in one manufacturing hall. To guarantee

addition to this, we also received the
order for further manufacture of the pipes
into spools ready for installation.
Competence in Welding
Technology
A particular requirement was the prefabrication
of the branches called “full couplings”.
Here special demands were made
on our know-how in welding technology.
The branches were supplied with a special
mechanical preparation of the weld edge
by our qualified welding staff and then
welded on by means of the TIG welding
procedure.
Finally BUTTING also manufactured the
welding brackets, the so-called weld-on
shoes. These are pipe brackets on which
the spools are laid in the completed
system.
Metallurgically clad Spools
We recently received an order from a
leading American-Canadian engineering
and construction company to supply

for the pipes was ASTM A516 grade 60,
along with the cladding material TP 317L.

steel plates, and the American
pipe standard, ASME B31.3, and extensive
project-specific quality requirements had
to be taken into account. The know-how
and experience of our staff in forming and
welding technology and in mechanical
processing were required for the prefabrication
of these spools. In addition, pipe
pieces in Solid TP 316L were welded on
to the 18" branches: on the construction
site, the pipe was to be carried on through
these pieces. Through this prefabrication,
the high quality of the mixed weld and an
improved product quality could be guaranteed.
Projects in the oil and gas sector present
very high demands on both quality and
quantity – progress means always satisfying
these demands.

manufactured in 56.7 × 18.5 × 3.56 mm
size. The internal and external tubes of
the double tube system were in sizes
88.90 × 3.0 mm and 115.3 × 4.5 mm. For
process-related reasons, the double tubes
were each manufactured from two materials
(alloy 693 / alloy 602 CA or alloy 693 /
alloy 601 for the triangular tubes). Their
welding also presents a major challenge,
as does compliance with very strict dimension

in Shanghai won the entire order: from
measurement through procurement to
further processing of the individual components
into complete pipe systems and
their installation. So the scope of the
delivery for BUTTING China amounted
to a total of 5,000 m stainless steel pipes
of TP 316L material, and a number of fittings
and flanges. Following measurement
and prefabrication, there were sometimes
more than 25 BUTTING technicians working
to install 19 reactors, converters and
vaporizer units in the plant.

Demanding Products
Since 1973, BUTTING has been closely
linked with the shipbuilding industry as
a supplier of pipes, piping components,
flanges and prefabricated pipe parts. Thus
in previous years, BUTTING has equipped
and installed pipes on more than 200 gas
and chemicals tankers in collaboration
with shipyards in Croatia, Italy, Portugal,
France, Poland, China and Germany.

products after their assembly
This was possible because BUTTING satisfies
both the material requirements and
the manufacturing conditions for these
demanding special ships and also offers
complete delivery packages. The high
quality of the wide-ranging production
programme – supported by well-developed
in-house prefabrication – also guarantees
constant operating security for the
plant, for a small amount in investment
and follow-up costs.
At Home on all the seven
Seas
As a result of its long experience in processing
duplex steels, BUTTING won
an order from a Polish shipyard to supply
pipes, components and flanges of
between NB 25 and NB 400 in diameter
for a number of chemical tankers. For
heating the tank, we supplied about
19 km of pipes in size 54.0 × 2.0 mm in
12 metre lengths.
BUTTING prefabricated pipes for deck systems
in Knesebeck in line with isometric
and other drawings made by the shipyard.
The capacities for bending pipes, satisfying
the requirements of DNV in relation
to weld seam quality and the use of fullbody
pickling represented optimum conditions
for making high-quality products.

Duplex on Board
The Peene shipyard in Wolgast entrusted
BUTTING with supplying recessed bulkheads
for the cargo tank of a clean-up
ship, made from 1.4462 and 1.4565 materials.
The approximately 450 m of pipes for
the NB 50 heater coils, made from 1.4565,
were fabricated, bent and welded into
ready-to-lay sections. The scope of the
order also covered the entire piping material
including prefabrication for the cargo,
drinking water, fire extinguisher system
and the salt water high pressure system.
Quieter, quicker, deeper –
naval Ship-Building
The power systems of the future for building
ships for the German navy are implemented
with pipe bodies and components
made by BUTTING. That’s why we expanded
our product range to include the
production and supply of oxygen tanks
and H2 storage vessels for the fuel cells
of submarines. For this purpose, BUTTING
used the a-magnetic steel, 1.3964. Our
large experience and processing competence
in forming and joining technology
with this steel used at very low temperatures
were among the decisive factors in
winning this order. BUTTING constructed

the jackets of the tanks and the control
cabinets for the oxygen system of the submarines.
In addition, the reinforcing rings
were pulled over the jackets and welded.
The individual jackets were then connected
to two entire pipes (starboard and port
tanks), complying with very strict tolerances
of shape and position.
From the planning stage to commissioning
ready-for use pipe systems – including
those made from special alloys – we are
your reliable partner.

Pipes on their Way
into Space
Manufacturing piping components for
the aerospace industry is regarded as
especially challenging for a pipe manufacturer.
The use of BUTTING products in the
ARIANE carrier rocket system, in the ISS
space station and in Airbus planes demonstrate
our reliability and high-quality standards.
Since the mid-1970s, BUTTING has
continuously been manufacturing pipes and
piping components, for example as readyto-fit
pressurized gas and fuel lines and as
drainage pipes for the aerospace industry.
irregular geometric shapes with very high
testing and documentation requirements.
A Matter of Confidence
Manufacturing the equipped and PTG
lines for the ARIANE 5 ESC-A upper stage,
including the engineering, represented a
further challenge for BUTTING. This was
produced under our own responsibility,
complete with the appropriate external
procurement of semi-finished materials,
and to high-quality standards, and was
cleaned, tested and packaged under Class
100,000 cleanroom conditions.
Competent and reliable
In 1983 BUTTING began by manufacturing
a prototype and then went into batch production
of pressurized gas and fuel lines
(booster piping) made from the 1.4571
material for the ARIANE 4 PAL booster
rocket. The required semi-finished products,
such as pipes, elbows and flanges,
were manufactured completely, along
with the joining and testing equipment.
In 2002, the BUTTING manufacturing
team was given the ARIANE 4 production
award to commemorate almost 20 years
of successful collaboration.
Successful for Decades
In 1990 we received the order for semifinished
manufacturing at the EPC lower
stage of ARIANE 5. BUTTING fulfilled the
Piping component with pyro valve in
dimensions of 12 × 2 mm for the EPS
upper stage of the ARIANE 5
demanding requirements in relation to
accurate forming, welding quality and
geometric accuracy. Two years later we
won the order to manufacture the prototype,
and later the initial batch of piping
sets for the ARIANE 5 EPS upper stage.
These had to be geometrically prefabricated
using bending technology which
was easy to reproduce. Then they had to
be welded in a closed system and fitted
into a corresponding upper stage model.
For the ARIANE 5 EPS pipe system,
BUTTING is manufacturing small pipes
from 1.4544.9 and 1.4546.9 materials in
Fuel tanks and feedlines for the EPS upper stage of ARIANE 5 for the P4.2 test
equipment at DLR (German aircraft and aerospace centre) in Lampoldshausen
163 × 1.7 mm piping component for
the ARIANE 4 PAL booster fuel pipe
As a result of our recognized quality and
processing experience, BUTTING was
given the order to produce piping components
to equip the ISS International Space
Station. The delivery included piping components
made from 1.4404 material in
sizes 1/4", 3/8", 1/2" and 1".
As a result of this successful collaboration
with the aerospace industry, we also
won our first order for the production
of drain mast piping components. Since
then, BUTTING has regularly been supplying
piping components in welded constructions
of size 12 × 0.5 mm of 1.4546 /
1.4544 materials for AIRBUS planes.
