4 TECHNICAL SPECIFICATIONS The products outlined in this catalog - STANDARD SUPPORTS 00 - 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 s and in the type data sheets Unless epressly agreed otherwise, the stipulations in the catalog STANDARD SUPPORTS 00 apply to all our shipments.. STANDARD SUPPORTS. 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 comple 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. Definition Standard supports must fulfill the following criteria: component shapes are uniform and designed for optimum eploitation 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 0 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.. LISEGA STANDARD SUPPORTS. 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: 0 C operating temperature for pipe clamps and clamp bases 00kN nominal load for all mainly statically determined components 000kN nominal load for rigid struts and standard shock absorbers 000kN design load for large bore shock absorbers 900mm travel range for constant hangers 00mm travel range for spring hangers. 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 etra wide adjustment ranges fully compatible load ranges and connection dimensions favorable performance/weight ratios integrated installation aids 0.

5 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.. 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 but also increases safety. Above and beyond this, it is a prerequisite for the rational of standardized construction on the principle of the modular system. There's only ONE best solution!. LISEGA MODULAR SYSTEM. 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 etra 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. With the LICAD design system and corresponding logistics, significant rationalization effects can be achieved in engineering, design and installation.. Scope The standardization at LISEGA etends 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 situations.. s The standardized units are divided into 7 product s according to their basic modes of function (see diagram, page 0., and table, Standardized Components, page 0.).. Load s To guarantee compatible loads in unit combinations, the load spectrum is split into fied load s. Within a load (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 and thus compatible. Components of different product s can therefore be connected only within a uniform load to safe load chains and the faulty combination of different load s is precluded. As all units in a load are designed uniformly regarding strength, the stresses on a complete chain of components 0 The economic principle: = from the least possible effort the maimum possible profit = Total Cost Minimum/TCM ===================== s + load s + travel ranges + connection compatibility = Modular System =================== Modular System + CAD design + DP logitic systems = High tech =================== 0.

6 are uniformly determined. For permissible stresses, a difference is made between statically and dynamically determined components. The units in product s,,,, and 7 are stressed in only one load direction (statically or quasistatically) and are considered to be statically determined components. The components in Group, as well as their accessories, are loaded in alternating directions and are therefore regarded as dynamically determined components. s and load cases, are set out in the LISEGA load tables (see page 0.). The definition of load cases is regulated according to ASME III, Div. Subsection NF, ASME B./MSS SP8 and DIN 8800, VGB-R 0 L, KTA 0. The load table applies uniformly to all components in the LISEGA modular system and to other LISEGA units systematically connected to it, e.g. integral special designs (see load table, page 0.)..

For the statically determined components in Groups,,,, 7, the nominal load corresponds to the ma. adjustment load of the spring elements, such as spring hangers and constant hangers. The maimum 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 rod should therefore only be replaced in kind (see page.,.). 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 eploited. For Group (pipe connections) a limited area of overlapping in the load s 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 Group see.., page 0.. Ø Pin Dyn. defined components Load Nominal load [kn] Ø Pin 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 ma. epected operating load.

Travel ranges of static components Moving parts such as spring and constant hangers are divided into travel ranges corresponding to the usable spring travel of the standard springs employed. The appropriate travel range in each case is marked by the th digit of the type designation according to the following table. Constant hanger Travel range (mm) Designation No Spring hanger Travel range (mm) Designation No For spring hangers and supports ( Group ) the springs are already installed preset to appro. / of their nominal load. The initial load follows from this and the spring travel is correspondingly reduced... Shock absorber travel ranges The maimum strokes of LISEGA shock absorbers are divided into economical stroke ranges as standard, and are so designated in the th digit of the type designation according to the following table. Stroke (mm) Shock absorber Type / 0/ Design. No Type designation All components can be clearly identified via coded type designations. Si digits contain all the necessary information required.

Due to additional qualityassuring measures and materials with special certification, separate manufacture is however necessary.

13 In the field of nuclear, 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 th digit (for struts, the th digit). The relevant component documentation relates to this and to the fabrication order number. In this catalog, the standard design, i.e. nonnuclear s, provides the basis for the type designations. As the given functional data and unit dimensions are the same for nuclear s, 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 (.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 79- by the German TÜV AD-HPO, production and testing of pressure vessels, by the TÜV DIN 8800 T7 Etended 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 000 NF, DIN EN 79, AD HP and HP.

Supporting connections are produced corresponding to the material by qualified welders according to ASME IX or DIN EN 87, part. The welding procedure is qualified according to ASME IX and DIN EN SURFACE TREATMENT 8. 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 eternal use in aggressive conditions (coastal, industrial and chemical areas). The following coating systems are applied to the different products: 8..

CONNECTION DIMENSIONS 9. Installation dimension E For the simple determination of minimum installation lengths, the installation dimension E is given for all components ecept the connecting rods ( Group ). 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. Simple checks for installation possibilities through dimension E! 0.

16 Sensible devices on hand for readjusting installation lengths! 9. Regulation of the total installation length 9.. 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, by 00mm for spring hangers type, by the adjustment possibility of a turnbuckle, type for spring hangers type, by min. 0mm 9.. Rigid struts, type 9 The connections in rigid struts type 9 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. 0. OPERATIONAL BEHAVIOR 0. Function Constant hangers type 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 % in series production. The load adjustment follows with a level of accuracy of %. for spring hangers types and, the load bearing rod is fed through the weld-on support tube and fied with an adjustment nut. The adjustment can be made within the scope of the available threaded length of the rod. load F travel s All connection threads are supplied as right hand threads. 9.. Spring supports For spring supports types 8 and 9, 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. FN = nominal load F min = min. load (upwards) F ma = ma. 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 % within the ordered travel. 9.. Turnbuckle, type, tie rod, left hand/right hand thread, type For rigid hanging support arrangements with short installation lengths, a defined reserve length in the connection parts type 0 and usually enables sufficient length adjustment. For longer installation lengths, the use of a turnbuckle L/R, type, in conjunction with a tie rod L/R, type, is appropriate. For easy access, this combination should be arranged at the lower end of the load chain. load F operating load travel s FN SN S = nominal load = nominal travel (incl. reserve) = operating travel 0.

17 0. Spring relaation Conventional helical coil springs under load, depending on time and temperature factors, lose part of their tension by relaation (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 0%. 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 epected is anticipated via the process of hot setting from a longer coil length, producing corresponding prerelaation. Relaation measures are prescribed. They are an integral part of order processing and embrace the whole LISEGA.. 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 800 and NCA 000 incl. NF as well as DIN EN ISO 900 and KTA 0. The QMM applies in principle to both the conventional and nuclear fields. The etent of monitoring of materials and tests, as well as the documentation, can in each case be eactly adapted to special requirements by the use of etended QA levels. All international requirements concerning nuclear s can be covered. Corresponding qualifications are available and are regularly renewed..
