1. STANDARD SUPPORTS
1.1 RequirementsFor the support of industrial piping systems,the use of standard supports is regarded aswell proven, up-to-date technology.
Only a correspondingly high level of standar-dization in support components can adequatelysatisfy the justifiable demand for productsthat are technically top-class and economi-cally attractive at the same time. The complexrequirements 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 DefinitionStandard supports must fulfill the followingcriteria:
➜ component shapes are uniform and designed for optimum exploitation of material
➜ units are compatible regarding connectingdimensions and loading capacity
➜ units are cataloged and clearly identifiableby 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 inGerman plant construction (power plants),VGB guideline R 510 L, require the preferen-tial use of standard supports and define thecriteria as follows:
“Standard supports are pipe support com-ponents, the construction of which, in formand dimensions as well as in the designdata relating to loading capacity, is certificatedand cataloged, and which are manufacturedaccording to firmly established, reproducibleprocedures, e.g. series production”.
2. LISEGA STANDARD SUPPORTS
2.1 ScopeAt LISEGA, standard supports form the basisof a comprehensive performance package. A complete program from more than 8000standardized components thereby covers alloperational loads, temperatures and travelranges normally met in piping systems inindustrial plant construction:
➜ � 650°C operating temperature for pipe clamps and clamp bases
➜ 400kN nominal load for all mainly statically determined components
➜ 1000kN nominal load for rigid struts and standard shock absorbers
➜ 5000kN design load for large bore shock absorbers
➜ 900mm travel range for constant hangers
➜ 400mm travel range for spring hangers
2.2 Design featuresSpecially developed components are availablefor the various support functions. In thedesign and construction of the units, funda-mental design principles have been takeninto 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
TECHNICAL SPECIFICATIONS
The products outlined inthis catalog - STANDARDSUPPORTS 2010 - are fullyin line with the latest deve-lopments in support tech-nology and satisfy generalrequirements for plantinstallation at the highestlevel. For the generaldesign of LISEGA standardsupports, uniform criteriaare applied. They aredescribed in the followingTECHNICAL SPECIFICATIONSand are binding for thecontents of this catalog.Componentrelated featuresare outlined in the corre-sponding sections of theproduct groups and in thetype data sheets
Unless expressly agreedotherwise, the stipulationsin the catalog STANDARDSUPPORTS 2010 apply toall our shipments.
0.2
0The LISEGA modular system is specially targ-eted towards this efficiency. The standardi-zation of components forms the foundation andis the precondition for rational series produc-tion, dependable quality, systematic warehou-sing and computer assisted application. Withthe LICAD design system and correspondinglogistics, significant rationalization effectscan be achieved in engineering, design andinstallation.
3.2 ScopeThe standardization at LISEGA extends bey-ond the components to their systematic inte-raction. To this end, load and travel distri-bution as well as function and connectionsare meaningfully coordinated.
In this way the LISEGA standard supportprogram has been developed as a functionalmodular system with logical linking. The indi-vidual units form modules therein and arecompatible regarding loads and connections.This enables the formation of meaningful com-binations to produce support configurationsfulfilling all requirements. The large selectionof components makes adaptation possible towidely differing support and applicationsituations.
3.3 Product groupsThe standardized units are divided into 7product groups according to their basic modesof function (see diagram, page 0.3, and table,Standardized Components, page 0.4).
3.4 Load groupsTo guarantee compatible loads in unit com-binations, the load spectrum is split intofixed load groups.Within a load group (nominal load), all com-ponents feature uniform load limits and stresssafety characteristics. The connection shapesof the units (threads - either metric or UNCaccording to market area - or pin diameters)are uniform within a group and thus compat-ible. Components of different product groupscan therefore be connected only within a uni-form load group to safe load chains and thefaulty combination of different load groupsis precluded. As all units in a load group aredesigned uniformly regarding strength, thestresses on a complete chain of components
In addition, LISEGA hangers feature only oneupper attachment point. As a result, and duealso to the compact and symmetrical designshape, the load transfer free of moments tothe connecting elements is ensured and simple installation enabled. The operationalposition of the moving parts (hangers, supports and shock absorbers) can be readdirectly off a travel scale. Load adjustmentof the constant hangers and supports can bemodified at all times, also in the installedcondition under load. Hangers and supportscan be blocked in any travel position.
2.3 Principle of the optimum design typeFor the design of support components, opti-mum coverage of the specific support func-tion is the decisive factor. For each functiononly one component is therefore required,namely, the optimum one for the purpose.The project engineer is spared costly selectionfrom a series of alternative solutions. Thisnot only facilitates application but alsoincreases safety. Above and beyond this, itis a prerequisite for the rational applicationof standardized construction on the principleof the modular system.
➜ There's only ONE best solution!
3. LISEGA MODULAR SYSTEM
3.1 FundamentalsThe cost of pipe supports is a major elementin the total cost of a piping system. The cost of the supports is the accumulatedtotal 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 criticalfor the commissioning deadline and can,through delayed delivery, cause incalculableextra costs. The aim of LISEGA product stra-tegy is to forge, out of all the cost factors in-volved, the common cost minimum for theuser in the sense of the economic principle.
The economic principle:

groups and load cases, are set out in theLISEGA load tables (see page 0.5). The defini-tion of load cases is regulated according toASME III, Div. 1 Subsection NF, ASME B31.1/MSS SP58 and DIN 18800, VGB-R 510L, KTA 3205.The load table applies uniformly to all com-ponents in the LISEGA modular system andto other LISEGA units systematically connectedto it, e.g. integral special designs (see loadtable, page 0.5).

are uniformly determined.For permissible stresses, a difference is madebetween statically and dynamically determinedcomponents. The units in product groups 1,2, 4, 5, 6 and 7 are stressed in only oneload direction (statically or quasistatically)and are considered to be statically determinedcomponents. The components in ProductGroup 3, as well as their accessories, areloaded in alternating directions and are there-fore regarded as dynamically determinedcomponents.

Standardized components
3.5.1 Static componentsThe nominal load is used for the determin-ation of load groups. For the statically deter-mined components in Product Groups 1, 2,4, 6, 7, the nominal load corresponds to the max. adjustment load of the spring ele-ments, such as spring hangers and constanthangers. The maximum permissible hot load(load case H) lies considerably higher thanthe nominal load when components areused as rigid supports, and is tied to theload capacity of the connection threads.LISEGA threaded rod should therefore onlybe replaced in kind (see page 6.5, 6.6).
Spring and constant hangers in the blockedposition also count as rigid supports, where-by for cold loads in hydrostatic tests (shortduration) the emergency loads (level C) canbe exploited.
For Product Group 4 (pipe connections) a lim-ited area of overlapping in the load groupsis foreseen, due to the temperature-related,variable spectrum of loading capacities. Dataon the permissible loads relating to the res-pective operating temperature are set out forpipe connection components in the indivi-dual type data sheets.
For Product Group 5 see 3.5.5, page 0.5.
3.5.2 Dynamic componentsFor dynamically determinedunits, the stipulation of thenominal loads follows fromthe meaningful division ofthe standardizable loadspectrum. Here, the nominalload corresponds at thesame time to the operatingload for load event levelA/B (ASME).As these components aregenerally used to guard against emergencies, theload event level C (ASME),possibly even level D, isusually adopted as the max.expected operating load. In each case the projectengineer’s instructionsapply.

3.5.5 Product Group 5The units in Product Group 5, pipe clampbases for cold piping systems, cryogenicsystems, as well as roller bearings and pipesaddles, are regarded as statically determined,but are not directly connected with the hangersupports. As they are comparable with secon-dary steel components, they constitute a spe-cial group. The nominal load correspondshere to the max. operational load accordingto level A.
� Max. operating load for spring and constant hangers correspon-ding 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 resultfrom the normal operation of theplant, including start-up and shut-down, load tolerances and hydro-static tests.
� Loads outside normal operation are grouped hereunder, possibly also hydrostatic tests. In each case a final inspection of the whole support arrangement is recom-mended.
� For the given loads, the yield stress of components can be reached. In each case replacement is recommended.
� Hereunder all dynamic loadsare to be included that can pos-sibly result from plant operation,including pressure shock forcesfrom valve operation, and perhapsoperating basis earthquakes (OBE).
� Hereunder all the dynamicloads are grouped which lie out-side normal operation, as for example safe shutdown earthquakes(SSE). In each case a final inspec-tion of the whole support arrange-ment is recommended.
� Dynamic loads from faultedconditions. For the given loads,the yield stress of componentscan be reached. Replacement isrecommended in each case.
� Load groups 1 and 2 are loadand connection compatible, where-by load group 1 applies to thesmallest shock absorber and loadgroup 2 to the correspondingrigid struts and weld-on brackets.

03.6. Travel ranges
3.6.1 Travel ranges of static componentsMoving parts such as spring and constanthangers are divided into travel ranges corres-ponding to the usable spring travel of thestandard springs employed.The appropriate travel range in each case ismarked by the 4th digit of the type desig-nation according to the following table.
For spring hangers and supports (ProductGroup 2) the springs are already installedpreset to approx. 1/3 of their nominal load. The initial load follows from this and thespring travel is correspondingly reduced.
3.6.2 Shock absorber travel rangesThe maximum strokes of LISEGA shock ab-sorbers are divided into economical strokeranges as standard, and are so designatedin the 4th digit of the type designation ac-cording to the following table.
3.7 Type designation
All components can be clearly identified viacoded type designations. Six digits containall the necessary information required. The type designation system facilitates theuse of modern information technology andenables the unrestricted application of themodular system in current CAD programs.

COMPONENTS
6. QUALIFICATION LEVELS FOR STANDARD ANDNUCLEAR APPLICATIONStandard supports have the same functionboth in the conventional and in the nuclearfield of application, and therefore do not
differ in design. Due to additional quality-assuring measures and materials with spe-cial certification, separate manufacture is how-ever necessary.
4. STANDARDS AND CALCULATIONSIn design, stress and load calculations, aswell as in manufacturing, the relevant Germanand international standards, technical regu-lations and codes are taken into account.
MaterialEN Material-No. EN 10027-2 ASTM
The characteristic values of materials that alldesign calculations are based on are takenfrom the relevant standards and recognizedtechnical codes.
5.1 Preferred materials for pipe connection parts
Worldwide coverage of recognized codes and standards!
Standardized selection of high temperature materials!
0.10
0In the field of nuclear application, all mate-rials are traceable right through to the finishedproduct via heat number restamping, and thecomponents themselves are marked accor-ding to ASME and KTA regulations. In thetype designation, the nuclear design is notedin the 5th digit (for struts, the 6th digit). Therelevant component documentation relatesto this and to the fabrication order number.
In this catalog, the standard design, i.e. non-nuclear applications, provides the basis forthe type designations. As the given function-al data and unit dimensions are the same fornuclear applications, selection can also bemade here with the help of the catalog. On planning or ordering, attention must how-ever be paid to corresponding conformity ofthe type designations. The table showing thetype designation system (3.8, page 0.7) can beconsulted in this respect.
7. WELDINGAll welding is carried out as gas metal arcwelding - 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 qua-lified according to ASME III NCA 4000 NF,DIN EN 719, AD HP3 and HP4. Non-destructive tests are carried out by testingstaff qualified acc. to ASME IX and DIN EN473, level 2, and SNT-TC-1A, level II.
Supporting connections are produced corres-ponding to the material group by qualifiedwelders according to ASME IX or DIN EN287, part 1. The welding procedure is quali-fied according to ASME IX and DIN EN 288.
8. SURFACE TREATMENT
8.1 Standard coating systemsThe surfaces of LISEGA products are protectedas standard from corrosive influences by highquality protection systems that are also sui-table 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 coatingComponents that are either to be welded to existing structure in the plant or simplyrequire higher quality transport protection arecoated on a bright metal surface with wel-dable primer (thickness app. 30µm, color reddish brown).
8.1.2 ElectrogalvanizingSpring hangers and supports up to load size9, as well as all threaded parts and specialfunction parts, are electrogalvanized (zincthickness app. 15µm, yellow chromatized).UNC threaded parts are white chromatized.
8.1.3 Paint coatingsConstant hangers and supports and otherproducts according to table 8.2 receive thefollowing surface treatment:
1. Steel grit blasting according to SP-6 orSP-10 for the U.S. and EN ISO 12944-4grade SA 2 1/2 for Europe.
2. Undercoat of 1-component polyurethanezinc dust primer, dry film thickness 60µm,approx. 62% zinc in solid state volume,color grey.
3. Final coating of 2-component acrylic poly-urethane paint, dry film thickness 60µm,color RAL 5012, light blue.
The total dry film thickness of the systemamounts to approx. 120µm.
8.1.4 Hot dip galvanizationRoller bearings, pipe saddles and cryogenicpipe clamp bases are hot dip galvanized asstandard, zinc thickness approx. 60µm.

8.2 Standard surface protection in order of products (corresp. to 8.1)
8.3 Extended surface protectionFor applications in the open involving highlycorrosive conditions, such as coastal sites orchemical plants, extra protection can be sup-plied, insofar as this has not already beenprovided as standard by hot dip galvanizingor special steel versions. The following coa-ting systems are thereby applied:
8.3.1 Electrogalvanization with additionalcoats of paint1. A barrier layer (dry film thickness 30µm)is applied to the galvanized surface acc. to 8.1.2.
2. As a final layer, a 2-component acrylicpolyurethane finish (dry film thickness 60µm,color RAL 5012 - light blue) is applied.
8.1.5 Stainless steel designsShock absorbers and energy absorbers (E-Bars) are made entirely of non-corrodingmaterials. Connecting parts are electrogal-vanized according to 8.1.2.
8.1.6 Cathodic immersion process (CIP)All LISEGA springs are given special treat-ment because of their distinctive functional
significance. The peeled surface of the springsis steel ball blasted and zinc-phosphated; sub-sequently a 2-component epoxy resin coatingis applied via electroimmersion and thenburnt in at approx. 200°C (CIP). This highlysophisticated process has been adoptedfrom the automobile industry.

9. CONNECTION DIMENSIONS
9.1 Installation dimension EFor the simple determination of minimuminstallation lengths, the installation dimen-sion E is given for all components except theconnecting rods (Product Group 6). Thisdimension comprises the installation lengthminus the engaging length of the connectingpart. For load chains, the E therefore desig-nates the complete rod section.
Special product-related features are to betaken into account as follows:
0
To determine the total length of the rods ina load chain, all the E dimensions are to beadded together. The sum of these is then tobe compared with the total installation length.If the resulting difference is greater than thesum of the engagement depths (X dimensions),the chain selected is appropriate for the totalinstallation height.
For load chains consisting solely of pin con-nections, the minimum installation dimensionfollows from the sum of all E dimensions.
8.3.2 Extra paint layerOver the standard paint coating according to8.1.3, a third protective layer consisting of a2-component acrylic polyurethane coating isapplied. Dry film thickness 60µm, color RAL5012 - light blue, total dry film thickness app.180µm.
8.3.3 Hot dip galvanizingHot dip galvanized surface, layer thicknessapprox. 60µm, bolts approx. 40µm.

Sensible devices on handfor readjusting installationlengths!
9.2 Regulation of the total installationlength
9.2.1 Turnbuckle function of the connectingthreadsFor length adjustment in installation condition(adjustment of pipe installation position, ac-tuation of loading), the lower connections inconstant and spring hangers provide a turn-buckle function. This way, subsequent adjust-ment of the installation lengths (attachmentrods) within a sufficient range is possible:
➜ for constant hangers type 11, by 300mm
➜ for spring hangers type 21, by the adjustment possibility of a turnbuckle, type 62
➜ for spring hangers type 22, by min. 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 avai-lable threaded length of the rod.
All connection threads are supplied as righthand threads.
9.2.2 Spring supportsFor spring supports types 28 and 29, theinstallation height can be regulated by thesupport tube, functioning as a spindle inde-pendently of the presetting. The necessary load is actuated on installationby screwing the support tube upwards.
9.2.3 Turnbuckle, type 62, tie rod, lefthand/right hand thread, type 65For rigid hanging support arrangements withshort installation lengths, a defined reservelength in the connection parts type 60 and61 usually enables sufficient length adjust-ment. For longer installation lengths, the useof a turnbuckle L/R, type 62, in conjunctionwith a tie rod L/R, type 65, is appropriate.For easy access, this combination should bearranged at the lower end of the load chain.
9.2.4 Rigid struts, type 39The connections in rigid struts type 39 aresupplied as left/right, with fine threading forlength adjustment in the installation conditionas standard.Flat faces on the body of the rigid struts en-able simple adjustment with a wrench.
10. OPERATIONAL BEHAVIOR
10.1 FunctionConstant hangers type 1 are designed so thatin theory no load deviation occurs over thewhole range of action. The total deviationresulting from springs, bearing friction, andfabrication tolerances is held to within � 5%in series production. The load adjustment follows with a level ofaccuracy of 2%.
For spring hangers and supports, the loadalters linearly corresponding to the springtravel. The deviation of the spring force fromtheoretical values, resulting from spring hys-teresis and fabrication tolerances, amounts toless than � 5% within the ordered travel.

11.2 Quality management program, QMPThe QMP is clearly laid out in a quality ma-nagement manual, QMM, and regulates all thequality-assuring activities in the company.The QMM covers the organization as a whole,whereby the observance of rules is monitoredby the independent quality management de-partment QM. The QMM has been compiledaccording to international quality norms andstandards and specifically takes into accountthe regulations according to ASME III - NCA3800 and NCA 4000 incl. NF as well as DINEN ISO 9001 and KTA 1401.
The QMM applies in principle to both the con-ventional and nuclear fields. The extent ofmonitoring of materials and tests, as well asthe documentation, can in each case be exactly adapted to special requirements by theuse of extended QA levels. All internationalrequirements concerning nuclear applicationscan be covered. Corresponding qualificationsare available and are regularly renewed.

11.3 International qualifications
QMP and Processing constitute a single entity!
10.2 Spring relaxation
Conventional helical coil springs under load,depending on time and temperature factors,lose part of their tension by relaxation (sett-ling loss), a loss that is not inconsiderable.If no appropriate measures are taken, forconstant and spring hangers this can in thelong run lead to a reduction in adjusted ul-timate load of more than 10%.
In contrast to common practice, LISEGA onlyuses springs that, through special treatment,permit no settling loss of any significance. In these springs the settling loss normally tobe expected is anticipated via the process ofhot setting from a longer coil length, prod-ucing corresponding prerelaxation.
11. QUALITY ASSURANCE
