The products outlined in

this catalog - STANDARD

SUPPORTS 2010 - are fully

in line with the latest developments

in support technology

and satisfy general

requirements for plant

installation at the highest

level. For the general

design of LISEGA standard

supports, uniform criteria

are applied. They are

described in the following

TECHNICAL SPECIFICATIONS

and are binding for the

contents of this catalog.

Componentrelated features

are outlined in the corresponding

sections of the

product groups and in the

type data sheets

Unless expressly agreed

otherwise, the stipulations

in the catalog STANDARD

SUPPORTS 2010 apply to

all our shipments.

1. STANDARD SUPPORTS

1.1 Requirements

For the support of industrial piping systems,

the use of standard supports is regarded as

well proven, up-to-date technology.

Only a correspondingly high level of standardization

in support components can adequately

satisfy the justifiable demand for products

that are technically top-class and economically

attractive at the same time. The complex

requirements for modern pipe supports are:

➜ reliable functioning

➜ maintenance-free operation

➜ low unit prices

➜ simple planning with DP systems

➜ instant availability

➜ economical installation strategy

➜ easy to install designs

➜ supplementary service benefits

1.2 Definition

Standard supports must fulfill the following

criteria:

➜ component shapes are uniform and

designed for optimum exploitation

of material

➜ units are compatible regarding connecting

dimensions and loading capacity

➜ units are cataloged and clearly identifiable

by a designation system

➜ components are manufactured in

series production

➜ components comply with the relevant

standards and international regulations

➜ functional capacity, suitability and

durability of the units is well proven

➜ components are certified and

approved for use

The relevant codes for pipe supports in

German plant construction (power plants),

VGB guideline R 510 L, require the preferential

use of standard supports and define the

criteria as follows:

“Standard supports are pipe support components,

the construction of which, in form

and dimensions as well as in the design

data relating to loading capacity, is certificated

and cataloged, and which are manufactured

according to firmly established, reproducible

procedures, e.g. series production”.

2. LISEGA STANDARD SUPPORTS

2.1 Scope

At LISEGA, standard supports form the basis

of a comprehensive performance package.

A complete program from more than 8000

standardized components thereby covers all

operational loads, temperatures and travel

ranges normally met in piping systems in

industrial plant construction:

➜ 1200°F operating temperature for

pipe clamps and clamp bases

➜ 90 kips nominal load for all mainly

statically determined components

➜ 224 kips nominal load for rigid struts

and standard shock absorbers

➜ 1124 kips design load for large bore

shock absorbers

➜ 36 inch travel range for constant hangers

➜ 16 inch travel range for spring hangers

2.2 Design features

Specially developed components are available

for the various support functions. In the

design and construction of the units, fundamental

design principles have been taken

into consideration:

➜ symmetrical design shapes

➜ compact installation dimensions

➜ especially reliable function principles

➜ extra wide adjustment ranges

➜ fully compatible load ranges and

connection dimensions

➜ favorable performance/weight ratios

➜ integrated installation aids


In addition, LISEGA hangers feature only one

upper attachment point. As a result, and due

also to the compact and symmetrical design

shape, the load transfer free of moments to

the connecting elements is ensured and

simple installation enabled. The operational

position of the moving parts (hangers,

supports and shock absorbers) can be read

directly off a travel scale. Load adjustment

of the constant hangers and supports can be

modified at all times, also in the installed

condition under load. Hangers and supports

can be blocked in any travel position.

2.3 Principle of the optimum design type

For the design of support components, optimum

coverage of the specific support function

is the decisive factor. For each function

only one component is therefore required,

namely, the optimum one for the purpose.

The project engineer is spared costly selection

from a series of alternative solutions. This

not only facilitates application but also

increases safety. Above and beyond this, it

is a prerequisite for the rational application

of standardized construction on the principle

of the modular system.

➜ There’s only ONE best solution!

3. LISEGA MODULAR SYSTEM

3.1 Fundamentals

The cost of pipe supports is a major element

in the total cost of a piping system.

The cost of the supports is the accumulated

total cost arising from:

➜ project management (processing)

➜ design and engineering work

➜ use of materials (components) as well as

➜ installation work

The pipe supports are almost always critical

for the commissioning deadline and can,

through delayed delivery, cause incalculable

extra costs. The aim of LISEGA product strategy

is to forge, out of all the cost factors involved,

the common cost minimum for the

user in the sense of the economic principle.

The LISEGA modular system is specially targeted

towards this efficiency. The standardization

of components forms the foundation and

is the precondition for rational series production,

dependable quality, systematic warehousing

and computer assisted application. With

the LICAD design system and corresponding

logistics, significant rationalization effects

can be achieved in engineering, design and

installation.

3.2 Scope

The standardization at LISEGA extends beyond

the components to their systematic interaction.

To this end, load and travel distribution

as well as function and connections

are meaningfully coordinated.

In this way the LISEGA standard support

program has been developed as a functional

modular system with logical linking. The individual

units form modules therein and are

compatible regarding loads and connections.

This enables the formation of meaningful combinations

to produce support configurations

fulfilling all requirements. The large selection

of components makes adaptation possible to

widely differing support and application

situations.

3.3 Product groups

The standardized units are divided into 7

product groups according to their basic modes

of function (see diagram, page 0.3, and table,

Standardized Components, page 0.4).

3.4 Load groups

To guarantee compatible loads in unit combinations,

the load spectrum is split into

fixed load groups.

Within a load group (nominal load), all components

feature uniform load limits and stress

safety characteristics. The connection shapes

of the units (threads - either metric or UNC

according to market area - or pin diameters)

are uniform within a group and thus compatible.

Components of different product groups

can therefore be connected only within a uniform

load group to safe load chains and the

faulty combination of different load groups

is precluded. As all units in a load group are

designed uniformly regarding strength, the

stresses on a complete chain of components

0

The economic principle:

= from the least possible

effort the maximum

possible profit

are uniformly determined.

For permissible stresses, a difference is made

between statically and dynamically determined

components. The units in product groups 1,

2, 4, 5, 6 and 7 are stressed in only one

load direction (statically or quasistatically)

and are considered to be statically determined

components. The components in Product

Group 3, as well as their accessories, are

loaded in alternating directions and are therefore

regarded as dynamically determined

components.

3.5.1 Static components

The nominal load is used for the determination

of load groups. For the statically determined

components in Product Groups 1, 2,

4, 6, 7, the nominal load corresponds to

the max. adjustment load of the spring elements,

such as spring hangers and constant

hangers. The maximum permissible hot load

(load case H) lies considerably higher than

the nominal load when components are

used as rigid supports, and is tied to the

load capacity of the connection threads.

LISEGA threaded rods should therefore only

be replaced in kind (see page 6.5, 6.6).

Spring and constant hangers in the blocked

position also count as rigid supports, whereby

for cold loads in hydrostatic tests (short

duration) the emergency loads (level C) can

be exploited.

For Product Group 4 (pipe connections) a limited

area of overlapping in the load groups

is foreseen, due to the temperature-related,

variable spectrum of loading capacities. Data

on the permissible loads relating to the respective

operating temperature are set out for

pipe connection components in the individual

type data sheets.

For Product Group 5 see 3.5.5, page 0.5.

3.5.2 Dynamic components

For dynamically determined

units, the stipulation of the

nominal loads follows from

the meaningful division of

the standardizable load

spectrum. Here, the nominal

load corresponds at the

same time to the operating

load for load event level

A/B (ASME).

As these components are

generally used to guard

against emergencies, the

load event level C (ASME),

possibly even level D, is

usually adopted as the max.

expected operating load.

In each case the project

engineer’s instructions

apply.

0.4


Max. operating load for spring

and constant hangers corresponding

to max. load on load springs.

Permissible loads according to

the design criteria for US code

MSS SP 58 (ASME B 31.1).

All loads are to be included

hereunder that can possibly result

from the normal operation of the

plant, including start-up and shutdown,

load tolerances and hydrostatic

tests.

Loads outside normal operation

are grouped hereunder, possibly

also hydrostatic tests. In each case

a final inspection of the whole

support arrangement is recommended.

For the given loads, the yield

stress of components can be

reached. In each case replacement

is recommended.

Hereunder all dynamic loads

are to be included that can possibly

result from plant operation,

including pressure shock forces

from valve operation, and perhaps

operating basis earthquakes (OBE).

Hereunder all the dynamic

loads are grouped which lie outside

normal operation, as for

example safe shutdown earthquakes

(SSE). In each case a final inspection

of the whole support arrangement

is recommended.

Dynamic loads from faulted

conditions. For the given loads,

the yield stress of components

can be reached. Replacement is

recommended in each case.

Load groups 1 and 2 are load

and connection compatible, whereby

load group 1 applies to the

smallest shock absorber and load

group 2 to the corresponding

rigid struts and weld-on brackets.

bases for cold piping systems, cryogenic

systems, as well as roller bearings and pipe

saddles, are regarded as statically determined,

but are not directly connected with the hanger

supports. As they are comparable with secondary

steel components, they constitute a special

3.7 Type designation

All components can be clearly identified via

coded type designations. Six digits contain

all the necessary information required.

The type designation system facilitates the

use of modern information technology and

enables the unrestricted application of the

modular system in current CAD programs.

Standard supports have the same function

both in the conventional and in the nuclear

field of application, and therefore do not

The characteristic values of materials that all

design calculations are based on are taken

from the relevant standards and recognized

technical codes.

As a matter of principle, only materials of

guaranteed strength properties are used for

supporting components.

differ in design. Due to additional qualityassuring

measures and materials with special

certification, separate manufacture is however

necessary.


In the field of nuclear application, all materials

are traceable right through to the finished

product via heat number restamping, and the

components themselves are marked according

to ASME and KTA regulations. In the

type designation, the nuclear design is noted

in the 5th digit (for struts, the 6th digit). The

relevant component documentation relates

to this and to the fabrication order number.

In this catalog, the standard design, i.e. nonnuclear

applications, provides the basis for

the type designations. As the given functional

data and unit dimensions are the same for

nuclear applications, selection can also be

made here with the help of the catalog.

On planning or ordering, attention must however

be paid to corresponding conformity of

the type designations. The table showing the

type designation system (3.8, page 0.7) can be

consulted in this respect.

7. WELDING

All welding is carried out as gas metal arc

welding - in special cases by stick welding.

LISEGA holds certifications according to:

➜ ASME III Div I NCA NPT stamp

➜ DIN EN 729-2 by the German TÜV

➜ AD-HPO, production and testing of

pressure vessels, by the TÜV

➜ DIN 18800 T7 Extended suitability

certification for steelwork and bridge

construction by the SLV, the training

and testing institute for welding

technology

LISEGA welding inspection personnel are qualified

according to ASME III NCA 4000 NF,

DIN EN 719, AD HP3 and HP4. Nondestructive

tests are carried out by testing

staff qualified acc. to ASME IX and DIN EN

473, level 2, and SNT-TC-1A, level II.

Supporting connections are produced corresponding

to the material group by qualified

welders according to ASME IX or DIN EN

287, part 1. The welding procedure is qualified

according to ASME IX and DIN EN 288.

8. SURFACE TREATMENT

8.1 Standard coating systems

The surfaces of LISEGA products are protected

as standard from corrosive influences by high

quality protection systems that are also suitable

for external use in aggressive conditions

(coastal, industrial and chemical areas).

The following coating systems are applied

to the different products:

8.1.1 Primer coating

Components that are either to be welded

to existing structure in the plant or simply

require higher quality transport protection are

coated on a bright metal surface with weldable

primer (thickness app. 1.18 mil [30µm],

color reddish brown).

8.1.2 Electrogalvanizing

Spring hangers and supports up to load size

9, as well as all threaded parts and special

function parts, are electrogalvanized (zinc

thickness app. 0.59 mil [15µm], yellow chromatized).

UNC threaded parts are white chromatized.

8.1.3 Paint coatings

Constant hangers and supports and other

products according to table 8.2 receive the

following surface treatment:

1. Steel grit blasting according to SP-6 or

SP-10 for the U.S. and EN ISO 12944-4

8.3 Extended surface protection

For applications in the open involving highly

corrosive conditions, such as coastal sites or

chemical plants, extra protection can be supplied,

insofar as this has not already been

provided as standard by hot dip galvanizing

or special steel versions. The following coating

systems are thereby applied:

significance. The peeled surface of the springs

is steel ball blasted and zinc-phosphated; subsequently

a 2-component epoxy resin coating

is applied via electroimmersion and then

burnt in at approx. 392°F [200°C] (CIP).

This highly sophisticated process has been

adopted from the automobile industry.

For applications in specially aggressive atmospheres,

e.g. coastal areas, certain industrial

gases or offshore, special measures are to be

agreed on.

9. CONNECTION DIMENSIONS

9.1 Installation dimension E

For the simple determination of minimum

installation lengths, the installation dimension

E is given for all components except the

connecting rods (Product Group 6). This

dimension comprises the installation length

minus the engaging length of the connecting

part. For load chains, the E therefore designates

the complete rod section.

Special product-related features are to be

taken into account as follows:

To determine the total length of the rods in

a load chain, all the E dimensions are to be

added together. The sum of these is then to

be compared with the total installation length.

If the resulting difference is greater than the

sum of the engagement depths (X dimensions),

the chain selected is appropriate for the total

installation height.

For load chains consisting solely of pin connections,

the minimum installation dimension

follows from the sum of all E dimensions.

9.2 Regulation of the total installation

length

9.2.1 Turnbuckle function of the connecting

threads

For length adjustment in installation condition

(adjustment of pipe installation position, actuation

of loading), the lower connections in

constant and spring hangers provide a turnbuckle

function. This way, subsequent adjustment

of the installation lengths (attachment

rods) within a sufficient range is possible:

➜ for constant hangers type 11,

by 11 3 /4 inch [300mm]

➜ for spring hangers type 21, by the

adjustment possibility of a turnbuckle,

type 62

➜ for spring hangers type 22,

by min. 5 1 /2 inch [140mm]

➜ for spring hangers types 25 and 26,

the load bearing rod is fed through the

weld-on support tube and fixed with

an adjustment nut. The adjustment can

be made within the scope of the available

threaded length of the rod.

All connection threads are supplied as right

hand threads.

9.2.2 Spring supports

For spring supports types 28 and 29, the

installation height can be regulated by the

support tube, functioning as a spindle independently

of the presetting.

The necessary load is actuated on installation

by screwing the support tube upwards.

9.2.3 Turnbuckle, type 62, tie rod, left

hand/right hand thread, type 65

For rigid hanging support arrangements with

short installation lengths, a defined reserve

length in the connection parts type 60 and

61 usually enables sufficient length adjustment.

For longer installation lengths, the use

of a turnbuckle L/R, type 62, in conjunction

with a tie rod L/R, type 65, is appropriate.

For easy access, this combination should be

arranged at the lower end of the load chain.

9.2.4 Rigid struts, type 39

The connections in rigid struts type 39 are

supplied as left/right, with fine threading for

length adjustment in the installation condition

as standard.

Flat faces on the body of the rigid struts enable

simple adjustment with a wrench.

10. OPERATIONAL BEHAVIOR

10.1 Function

Constant hangers type 1 are designed so that

in theory no load deviation occurs over the

whole range of action. The total deviation

resulting from springs, bearing friction, and

fabrication tolerances is held to within 5%

in series production.

The load adjustment follows with a level of

accuracy of 2%.

load F

FN = nominal load

F min = min. load (upwards)

F max = max. load (downwards)

SN = nominal travel (incl. reserve)

For spring hangers and supports, the load

alters linearly corresponding to the spring

travel. The deviation of the spring force from

theoretical values, resulting from spring hysteresis

and fabrication tolerances, amounts to

less than 5% within the ordered travel.

FN = nominal load

SN = nominal travel (incl. reserve)

S = operating travel

10.2 Spring relaxation

Conventional helical coil springs under load,

depending on time and temperature factors,

lose part of their tension by relaxation (settling

loss), a loss that is not inconsiderable.

If no appropriate measures are taken, for

constant and spring hangers this can in the

long run lead to a reduction in adjusted ultimate

load of more than 10%.

In contrast to common practice, LISEGA only

uses springs that, through special treatment,

permit no settling loss of any significance.

In these springs the settling loss normally to

be expected is anticipated via the process of

hot setting from a longer coil length, producing

corresponding prerelaxation.

11. QUALITY ASSURANCE

11.1 Fundamentals

Superior product quality has an important place

among the fundamental company goals at

LISEGA and also involves the activities of

and relationships with our business partners.

The organization and attitudes of those working

in the company are correspondingly attuned

to this aim. In a quality management

program (QMP), special quality-assuring

measures are prescribed. They are an integral

part of order processing and embrace the

whole LISEGA group.

11.2 Quality management program, QMP

The QMP is clearly laid out in a quality management

manual, QMM, and regulates all the

quality-assuring activities in the company.

The QMM covers the organization as a whole,

whereby the observance of rules is monitored

by the independent quality management department

QM. The QMM has been compiled

according to international quality norms and

standards and specifically takes into account

the regulations according to ASME III - NCA

3800 and NCA 4000 incl. NF as well as DIN

EN ISO 9001 and KTA 1401.

The QMM applies in principle to both the conventional

and nuclear fields. The extent of

monitoring of materials and tests, as well as

the documentation, can in each case be

exactly adapted to special requirements by the

use of extended QA levels. All international

requirements concerning nuclear applications

can be covered. Corresponding qualifications

are available and are regularly renewed.

11.4 Tests and qualifications

11.4.1 Raw material and material reception

All materials used undergo receiving control

by the quality management department. The

materials used are qualified, corresponding

to requirements by material tests according

to ASME and DIN EN 10204.

11.4.2 Monitoring of manufacture

Manufacture is monitored via accompanying

quality control according to the QM manual.

In particular, for nuclear applications the

quality-assuring requirements according to

ASME III NF and KTA are fulfilled.

11.4.3 Final inspection

Before shipment, constant and spring hangers

as well as shock absorbers undergo a function

test on test benches by quality management

personnel. The tests are carried out

using computer-assisted equipment. The

values measured can be recorded by means

of a diagram. In addition, for constant and

spring hangers the digital values can be

printed out over the whole travel range.

The specific test benches employed undergo

regular inspections by an independent supervisory

body.

11.4.4 Documentation on shipment

If so ordered, the materials used are documented

by certification from material tests according

to ASME and DIN EN 10204. In addition,

the results of the function tests can be

confirmed by issuing an acceptance test

certificate, also from a supervisory body if

desired.

Stress reports according to particular specifications

and quality-assuring documents can

be agreed between customer, manufacturer

and supervisory body.

11.5 Suitability test according to KTA 3205.3

and type test according to VGB R 510 L

For the use of series-made standard supports

in conventional power plants, a type test by a

supervisory body (according to § 14 of the

appliance safety law GSG) is foreseen in the

VGB code R 510 L.

For use in nuclear installations a corresponding

suitability test, according to directive 35

of the TÜV’s nuclear technology supervisory

body at the Vd TÜV, is prescribed by nuclear

code KTA 3205.3.

The test program prescribed comprises in

essence the following components:

➜ inspection of the quality management

program

➜ inspection of material used

➜ inspection of the design documentation

➜ inspection of design report summaries

➜ experimental function tests

➜ experimental overload tests

➜ experimental testing of continuous

load capacity

For the broad range of LISEGA products, type

and suitability tests have been conducted

by the German TÜV and VGB and the corresponding

permits granted. Qualifications can

be supplied on request
