3 Company Introduction The company Gradior s.r.o. was founded in the year 1996 under its former name GDV Energo, spol. s r.o. The company started as a technical bureau for designing of pipeline routings and fittings. The company was renamed to GRDIOR POWER s.r.o. in the year 2003 and it became a supplier of pipeline hangers and supports. Then it moved into the production hall within the industrial zone of Královopolské strojírny a.s. in Brno together with the manufacturing company GRDIOR STEEL, spol. s r.o. The company has been a member of the group MPS Holding a.s. since 2012; operating under its name, MPS Gradior s.r.o., it is a significant Czech manufacturer and hangers and supports for piping. The company managed to achieve progressive success on the national markets as well as on the demanding foreign markets. Pipeline fittings made by MPS Gradior s.r.o. are installed in systems operated in more than 30 countries in Europe, merica, sia and frica. Our products serve mainly in systems implemented within classical power engineering, nuclear power engineering, petrochemistry, distribution of heat and other industrial operations. We win our supply contracts mainly for convenient pricing, optional adaptation of assemblies and components to meet project requirements, employing genuine market and competitive means. We are the only Czech supplier of pipeline fittings with catalogued interior components of hanger assemblies, standard installation guidelines, data lists for assignment, checklists for installation check-ups and periodical monitoring of service life, supplemented with further supporting documentation and know-how. Our experience with design and production is based on continuous and extensive experience gained since ny feature within hanger or support assemblies have been designed in compliance with European and other global regulations applicable to industrial piping and steel structures. History and Progress Design and production of pipeline fittings were launched at the company GDV a.s. in 1996 upon takeover of the production programme from the former BB PBS based on the Czechoslovak technical standards. Our supports and hangers manufactured till the year 1997 were compliant with the Czechoslovak technical standards classed in ON 13 series. We launched the production of spring cages with respect to construction of EC Kladno. Evolution of these cages lasted till the year 2005, when GRDIOR POWER s.r.o. started producing modern moulded spring cages and threaded rods. That was the year, when we completed the progressive transfer of our entire product range from Czechoslovak technical standards to the European ones. Hanger and support assemblies have been tested on numerous installations, both in new developments as well as older systems, where these replace the initial ones no longer compliant with the existing reliability requirements. ll the catalogued components are standardised, which means they are rated for specific permitted loads and conforming to clearly specified and fulfilled production and delivery conditions. Our company has own research and development capacity in the field of design and its major power lies in adaptation of products to specific conditions of use or operation. nnual investments are made into technical and personnel development, innovations and upgrade of the production programme to match the current state of the art in engineering and science. The company follows its duly implemented and certified quality control system in compliance with standards ISO 9001, ISO and possesses its own inspection certificate for pressure equipment manufacturers according to PED. Organisation and Registered Office MPS Gradior s.r.o. currently employs fifty people in sales, project management, design, job engineering, production, quality control and dispatch. The premises comprise 10,000 m 2 of production and storage areas. The registered office is situated in the industrial area of Královopolská strojírna Brno, Křižíkova 188/68, Brno.

10 Pipe supports In terms of operating reliability of piping systems, the pipe supports represents an important element, which directly influences function of the plant and its durability. By in-correct function of the pipe supports, failures in operating reliability or even a serious damage to the piping system can occur. mong the consequences of the often failures in operation of supports there are, for instance, an overloading of the flanges resulting in leakage, overloading of the rotary equipment connected to the piping resulting in higher vibrations, overloading of the piping parts resulting in occurring possible cracks, mainly operating in creep range. For industrial piping it is useful to apply standard support assemblies considering the clearly determined requirements of function, consisting of type elements according to their purpose, load capacity and costs, which are decreased thanks to the mutual unification of the used elements. Type assemblies of pipe supports Gradior Pipe supports - division of basic assemblies ccording to the function, the basic assemblies can be divided as follows: RH SH CH SS FP GS VS CS BH GP SP RS UB CL - Rod Hanger - Spring Hanger - Constant Hanger - Sliding Support - Fix Point - Guide Support - Variable Support - Constant Support - Hanger for Pipe Racks - Guide Plate - PTFE Sliding Plate - Rigid Strut - U Bolt - Clip Overview of assemblies - clearly indicated function of the assembly enables a quick choice while designing the piping - assemblies of one type for different dimensions, loading and temperature, are the same as for the function and shape - hangers load chain consists of unified elements - assemblies and type elements follow the requirements of the EN and SME/MSS standards. - assemblies of setting consist of standardized elements, which have been designed with respect to the unification - one type (shape) of the element for a wide range of the operating loads and temperatures, mutual compatibility among the type assemblies and unified connecting dimensions for one group of load capacity. Support assemblies can be produced in different options, for instance, double-rod hanger for the horizontal or vertical piping. The options are distinguished: - by a digit behind the abbreviation RH or SH / CH concerning assemblies of hangers - directly by the catalogue type concerning other assemblies - assemblies of supports SS can be combined with the plates GP and SP Principle of assemblies code marking system is described in section of catalogue. pplication range The type assemblies of hangers, supports and their accessory, which consist of the catalogue elements, are meant for all the applications in power, chemical, and petrochemical industry. ccording to the dimensions, loading and operating temperatures they can be used for: - piping diameters DN15 - DN800 - loads up to 108 kn - operating temperatures from -20 C to +600 C - spring for operating travels up to 200mm For different operating ranges, e.g. pipe supports of larger dimensions, we will suggest and deliver a construction even beyond the dimension range stated in the catalogue. Order datalist To specify exactly all the requirements of setting, use the order datasheet, where all the main data of the assembly and type are predefined. Each assembly is determined by its function according to the following overview, further then by the piping diameter, main dimensions (dimensions stated in the icons of the overview), loads and travels, by the way of connecting to the structure and/or on basis of a further specification of the required type element (for instance, the support type or pipe clamp type). Possibility of deliveries for special constructions: - saddle and piping supports up to the diameter of 3000mm - fix points for high loading and operating temperatures - shoes and supports of the cryogenic piping - hangers of the membrane walls and chambers of the steam generators - assemblies including silent-blocks - supporting steel constructions B - 1

13 Connection of the hanger rods to the structure To connect the hanger rods to the steel structure, there are more possible options consisting of type elements. The type of connection is necessary to be specified in the order datasheet. ll the types fulfill the condition of a possible angle deviation of the rod up to 4 from the vertical axis. Connections of the specific load group are dimensioned for the highest load stated in the chart on page B-1. Type - spherical plate for setting onto U-channel beams. The connection art depends on the type of the auxiliary steel structure. In terms of the load transmission, all the types are equivalent. For higher rod angle deviations - more than 4 and for hanger assemblies of the RH2 and RH4 types, it shall be used a connection type B only. Overview of rod connections to structure Connections to construction Type B - weld on clevis for higher horizontal movements of piping. Type Type B Type C Type D Type C - weld on eye for standard use. Type D - connection clamp to the profile flange. Easy assembly without necessity to weld, e.g. for zinc-coated constructions. Setting of supports onto construction / floor To prevent the steel or supportive structures or floors from abrasion, we suggest to set the sliding supports at steel plates. The plates can be equipped with parts for guiding the supports in all directions at random clearance, or with the PTFE sliding plate to decrease friction between support and the base plate. The supports of 611, 614, 661, 664 types can be delivered together with a polyamide plate to prevent coat abrasion. The plates of the GP and SP types are delivered as options which can be welded or bolted to the structure, optionally connected to the floor via concrete anchors. The plates for the supports of the SS type correspond in dimensions to the base dimensions of the standard types of supports (type group 61x). For GS assemblies, it is necessary to use auxiliary bespoke structures.

15 pplication of spring hangers and supports for common cases of elimination of pipe movements resulting from thermal expansion. The application is suggested for pipe travels (mainly vertical) of supports up to 50mm. For higher values it is necessary to use constant hangers. Function - the spring support consists of a precompressed helical coil spring in a cylindrical housing, elements for travel indication and a turnbuckle nut for load adjustement at the assembly. The springs are supplied blocked and preset to the required load. Blocking is realised by a cluster inserted into holes of the casing and wrapped with a safety tape. fter piping erection or pressure test, deblocking of all spring supports shall be performed and checked! Load capacity of the blocked spring support at a pressure test is more than 2 times of nominal load. Spring supports of type series 100 to be used in load range from 0,2kN to 108kN. For higher loads we may deliver multi-spring cans acc. to request up to 336kN, all types of connection to hanger rods. Standard nominal spring travels are in 50, 100 a 200mm. For higher travel we may fabricate special cans, with springs in series connection, with nominal travels of 300 and 400mm. spring plate (lift indication) safety tape fixing cluster spring Spring supports 1 Travel Type Fn 1 - production group 600, 1200, nominal load in (N), see the chart on pgs 1-2 spring supports 1 - spring can for hangers, fixing type: clevis - threaded rod 1 - operating travel 50mm 2 - spring can for hangers, fixing type: rod - rod 2 - operating travel 100mm 3 - spring can for hangers, fixing type: support - rod 3 - operating travel 200mm 4 - spring can for support of double hangers of horizontal pipes 7 - spring support, type: sliding surface - support Materials and technology Helical coil springs are fabricated of steel types Federstahl C / DIN (cold coiled springs), and steel 51CrV-4 / EN (hot coiled springs). Springs are quenched to requested tesile strength and ballblasted. The spring is several times compressed to the block length by the can assembly, to be relaxed, and stresses in undersurface of wire are stabilised. Spring force remains constant by repeatet load or overload and creep relaxation is reduced to the minimum. ctual spring load during the operation in plant assembly does not drop by 2,5% under design load of node. Springs are designed and calculated acc. to non-linear plastic model, derived by GRDIOR.

For horizontal pipe travels higher than 10mm on support Types 1x7, it is recommended to use PTFE sliding plate. Support indication 1x7.T, combined with pipe shoe indicated.t (with SS polished plate). Use of springs in non-standard assemblies to be consulted with fabricator. 1-1

16 Overview of the spring sizes The spring size / travel is determined by the nominal load (maximum load of the spring in N) and by the nominal travel. spring indicated by size 1-12 corresponds to the nominal load. The springs for the hangers and supports are divided into eight basic sizes for loads of 0,2 to 63kN. For these sizes there are three nominal travels of 50, 100, 200mm. The springs of further sizes of 11 and 12, for loads up to 108kN are available only for the nominal travel 50 and 100mm. The force-travel relations and spring stiffness for all sizes are listed in table bellow. Load groups, determining the connecting size of the rod (see the overview of production group 8 connecting elements), are stated in the bottom line of table.

Furthermore, keep of travel reserve is necessary - 5mm to the upper and lower lift, or 20 percent of operating hanger travel. In some cases we recommend the load reserve to be 10% of spring set load. Caution: risk of complete hanger unload for the travels under label spring "0mm" value, or blocking of spring hanger, for the travels over maximum spring lift! Selection of the nominal spring travel is limited by the load deviation in range of a hot and cold state. The condition of the load change is determined from: df = (Fh - Fc) / Fh < 25% whereas Fh is the hot load and Fc cold load. Because of a higher stiffness, springs of a lower travel results to higher load changes, but their application is more economical and practital due to lower built-in length and weight. 1-2

17 Installation of spring hangers and supports shall be performed according to support manufacturer assembly drawing for each hanger. Spring hangers/supports are supplied blocked and preset to the required load. Before installation, the rods shall be cut to the required length, measured for each support at site. Positive length allowace for rods set in turnbuckle shall be at least 0,5*nominal spring travel. fter subsequent load adjustment the mimimum rod overlap must be at least 0,5*M (see fig.). In case of spring hangers 1x2 the top rod must be screwed into top plate to depth M and fastened down by safety nut. Deblocking and load adjustment Deblocking of spring support shall be executed after pipe cleaning, pressure test and insulating. Remove safety tape fastening the clusters inserted into spring hanger. t right load setting, when spring and pipe loads are equal, the blocking clusters may be put slightly out of hanger. If not, load shall be readjusted turning span nuts or turnbuckle, to achieve the balance. fter deblocking, a cluster shall be fasten to hanger rod or support casing, using a steel wire. It may be used for repetitionary pressure test Installation Hangers Type 1x2 are connected to rods screwed in upper spring plate and turnbuckle on the lower connection side.

32 Weld-on shoes are designed for use as an individual sliding supports or guidance for small horizontal load. pplication of weld-on shoes is convenient especially for operations in corrosive enviroments, for outdoor or subterranean piping. Use of clamp supports of type range 600 in such cases leads to moisture condensation and water retention in interstice between clamp and pipe, with consequential corrosive damage of pipe wall. Pipe shoes of type range 500 are welded to pipe wall by enclosed weld and after surface treatment the joint remains protected from corrosive damage Weld-on shoes Overview Type pplication SS - sliding support, equal height design SS - sliding support, equal height design Telescopic stanchion - sliding / fixed Telescopic dummy legs - sliding / fixed Limitations Use of weld-on shoes and stanchions is limited by danger of crack initiation in shoe/pipe weld joint, which may occur on piping with high operational temperatures. Different temperatures of pipe wall surface and shoe causes high load gradients in weld area. Thereby use of weld-on shoes is limited for temperatures up to 150 C and, considering another hazard effects, for low-pressure piping up to PN40. Weld joint can not be heat treated. Installation Position of weld-on shoe can not be adjusted after installation, therefore it is necessary to scale carefully the shoe position before welding, especially with regard to assumed pipe movements in operational condition. Shoes are welded by fillet welds according to assembly drawing. Welding method and plan is selected by installing organisation according to relevant rules for piping installation - parts integrally connected to pipe wall. Welds must be performed in such way that the residual tension in weld area is minimalized. Surface treatment Weld-on shoes are available in two surface treatment options: System 1 - top coat + weldable prime coat in weld area System 2 - galvanized + weldable prime coat in weld area fter welding it is necessary to perform surface treatment finishing - corrective prime coat and top coat in weld area. 5-1

48 Installation The sliding supports of type.1 is possible to set directly under the piping fixed in a required asembly height. Type.2 supports (horizontal clamp), set support shoe first before piping location. The same procedure for the fix points of the 652 type. The sliding supports are located to the steel or other sliding surfaces, which must be properly cleaned and surface-treated before assembly. The supports are welded only to the trapese beams of the double-rod hangers only. The fix points can be welded or bolted down to structure. Type.1 Type Installation For anchoring / guide plates see list 9-9 or notes at support drawing. Height adjustment of supports Steel structures under the supports must be levelled in such way, that the support will be visibly loaded and in contact with baseplate. desired level adjustment is possible using inserting plates, which must be firmly connected to the structure and fixed to avoid any movements. Height-adjustable supports of the 664 type shall be welded before release the temporary lifting devices of the piping. The welds are indicated in support assembly drawing. Coat on welded surfaces shall be applied. Height-adjustable supports of the 661 type, the bolted connections are tightened on the support shoe. The plates between each other must be clean and grease-free. The nuts are tightened according to the size at the same torque as the nuts of the type 652 clamps according to the following chart. safety fixing shall be done by a counter-nut. Tightening of bolt connections of sliding support pipe clamps The bolts of pipe clamps are tightened according to the following charts. For piping of DN>40, the nuts are secured by a counter-nut. proper tightening of the bolts is important to avoid slipping between the clamp and the pipe and load transfer from pipe surface to structure, especially for fix points and restraints.

62 Connecting elements Connecting elements of the hanger rods are used for load transmission from the pipe clamps to the structure. The type range is designed in the way of possibility of length adjustement. The assembly in combination with the elements of group 900 connection parts to the structure enables the angulation of rods from the vertical axis of 4. The highest allowable load of the connecting elements load chain according to the load capacity group are stated in section of the catalog. Each part is determined by a type number and a size the main dimension of the element is its diameter. With thread dimension over M30 the rod and pivot pin diameters are different. Connection of the eyenut type 832 to the pivot pin of the 850 type enables shift of one dimension, that means for a pivot pin on clamp of load capacity group 2 (diameter 16mm) it is possible to use the load chain of rod group 1 (diameter 12mm). This is valid in the case that a check of the highest loading of the particular chain elements has been carried out Connecting elements ll the elements must be fixed by counter-nuts, connecting nuts of the 824 type from both sides of the rod. Materials Threaded rod rolled, from material of strength group 4.6 for diameters up to M20, and from material S355J0 for diameters over M20.

66 Installation instructions Hanger rods shall be installed in vertical direction - except of the hangers with high horizontal movements where the rod may be preset in a cold condition under an angle given by the value designated by hanger drawing. The threaded rods are supplied in lengths with an assembly allowances rounded to +0,5m. To reach required length, the rods shall be cut at site. By installation, attention shall be paid to the screwed depth of all elements. The threaded length of the rod must be visible in all check holes Installation fter assembling of all hanger items, the rod must be tightened up to take over the weight of the piping. Tightening is done using turnbuckle in rod assembly or in a spring hanger. For the type of structure connection (square plate type 932), use the nuts above square plate. Before tightening all the counter-nuts of the rod, the screw-in depth of the threads shall be checked again. The counter-nuts to be tightened slightly with a flat spanner. The splits of the stud pins shall be properly splayed out after the assembly. different connecting way of the rods than using a coupling nuts type 824 is strictly forbidden. By an additional readjusment of the hanger rod length, the counter-nut of the turnbuckle shall be set loose. Other rod counter-nuts shall remain fixed. The thread of the turnbuckle shall be lubricated with an agent on basis of MoS. The reaction moment resulting from the rod turning is caught with a spanner at the upper and lower counter-nut of the particular rod element. fter adjusting, the counter-nuts to be tightened again. The hanger rods are maintenance-free with a correct assembly.
