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

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
