Limiters are recommended when it is not possi ble to secure the pipe system with sufficient fixed points or when a part relief of the fixed points is desired. The required limiters are measured to absorb also the reaction forces resulting from the test pressure. For the mainly required axial limitation the shown types with integrated tie bars have proved well. The tie bars with high stability (steel 8.8) can be adjusted to the actual installation meas urements.

42 HINTS FOR THE PIPEWORK DESIGNER ERV rubber expansion joints are delivered ready for installation. The swivelling flanges can be fitted in any desired position and have stabilising rims to ease the assembly. Flanges with stabilising rim (collar) also helps to maintain a safety gap between the ends of the screws and the bellow throughout the whole range of movement and avoids injuries. Correct Mating Flanges Seals are not required if the sealing surface of the mating flanges of the pipework are of the same size. Seals (as shown in fig. E) should be only used in order to prevent damage to the rubber sealing surface, for example if the mating flanges either have a larger internal diameter, sharp edges or irregularities e.g. welding beads. Crushing Strength The maximum operating pressure and test pressure not only depends on the burst pressure of the rubber bellow but can also be affected by operating temperature and design pressure / nominal pressure of the used flanges. For full details please see page 1-6. The burst pressure (at room temperature) is at least 3-4 times the nominal pressure (PN). Pressure test certificates can be issued upon request. Vacuum Resistance The maximum vacuum depends on size, operating temperature, length of installation and the installation of vacuum support rings (page 1-106). Please see type specific data sheets for details. The vacuum resistance can be slightly increased even without vacuum support rings if the installation length is shortened (e. g. by 20 mm). The vacuum resistance decreases if a longer installation length is chosen, or the expansion joint is lengthened in operation. Weather and Heat Resistance The outer rubber (cover) is resistant against weathering and protects the reinforcements against ageing, abrasion and corrosion. For the permitted temperature range please see type specific data sheets. For permanently warm operating conditions including external radiation heat please see page 1-6. ERV types with an outer rubber of CR or Hypalon (CSM) are (within limits) oil proof and flame resistant. An additional flame protection can be achieved by using a flame protection cover conforming to the 'Germanischer Lloyd' standard, see pages and Pressure Loss The internal design of the ERV bellows allows a high flow with little turbulence. Therefore the pressure loss is usually neglectible, even when dealing with high flow rates. Noise Levels Due to their design, ERV expansion joints reduce noise in pipelines. An even better reduction is achieved if the total installation length is shortened in a range of 5-10 mm. Installation For the allowable range of movement please see type specific data sheets. If possible, the length of the installation gap is designed to be equal to the recommended installation length, or slightly shorter. The low inherent resistance of ERV allows a compression by hand and makes fitting into smaller gaps easy. For larger installation gaps or lateral offset, not more than 50% of the maximum area of movement should be used up in order to leave a reserve for operation. If the bellows is lengthened during operation, a jolted (compressed) installation is recommended. The position of installation must be accessible for visual examination. When installing the unit, installation hints (page 1-109) must be observed. Restraint The inherent resistance of ERV bellows is negligible in respect of calculations for anchorage points. Under pressure the bellow acts like a plunger, thus requiring to fix anchorage points for larger size expension joints. Since the ERV construction absorbs part of these forces, the anchorage points may be correspondingly weaker. If such anchorage points cannot be provided, or if the stability of the other fittings is insufficient, the pressure thrust forces have to be absorbed by tie rods.

43 For Technical Assistance and Sales Contact: FlexEJ Ltd Tel: +44 (0) Fax: +44 (0) Web: Section 1 Installation and Operation Hints for ERV Expansion Joints ELAFLEX expansion joints are provided ready for installation. The standard flanges can be turned into any desired position. Additional sealings usually are not necessary. For installation please observe the following : 1) Prior to the installation of the expansion joint ensure that the mating flanges have satisfactory sealing surfaces. Pro truding pipe ends, grooves and tongues are not permitted as the sealing surface of the bellows might be destroyed. (see hints for the pipework designer, page 1-108) Attention: When using slip-on flanges the outside diameter must be larger than the sealing surface of the expansion joint. 2) Pay attention to the correct installation length: The pulling of expansion joints into installation gaps which are too large will lengthen the rubber bellow and might lead to the collar being drawn out of the flange groove (see picture). During the subsequent tightening of the screws the collar of the bellows would be crushed asymmetrically. Please note: A considerable lengthening during installation decreases the allowable range of movement during operation. To shorten installation gaps, distance flanges are available. 3) If possible install the expansion joints in such way that the date of production is visible. 4) Screws should be inserted from the expansion joint side. If this is not feasible, it must be assured that the bellows may not touch the screws in all operating conditions. 5) We recommend to use bolts of property class 8.8. The bolts have to be fastened crosswise in 3 uniform steps. When using a torque wrench: 1st step: Tighten bolts equally by hand (pay attention to parallel sealing surfaces!). 2nd step: Fasten crosswise with torque 50 Nm. 3rd step: Fasten crosswise approx. torque up to DN 80 max. 80 Nm up to DN 300 max. 100 Nm up to DN 500 max. 130 Nm DN Nm DN Nm DN Nm DN Nm Do not use any sharp-edged tools which might damage the rubber bellow in case the tool slips. 6) If no torque wrench can be used during installation, the screws may only be tightened to an extent that between the metal flanges a distance "y" of at least 1 mm remains (see picture). 7) The test pressure of a bellow or flange is 1.5 x PN. This value depends on which component is weaker. 8) The rubber bellow of the expansion joint must not be painted! Solvents can damage the rubber cover, furthermore the colour coat impedes a proper visual inspection. 9) When welding and cutting, the rubber bellow must be protected against heat by all means. For electric welding it must be insured that the electric current does not pass through the bellows. 10) Permanent radiation heat above 90 C must be avoided. If necessary flame protection covers should be used (see page 1-107). 11) Rubber expansion joints are subject to wear and must be included to routine inspection of the pipe system (visual inspection of the expansion joint regarding damages as well as inspection for hardening by pushing in with a thumb). wrong larger than recommended max. installation length Note : : the The bellows may not not touch the screws in in all all operating conditions.. l e s s than or equal to recomm. max. installation length correct min. 1 mm FlexEJ copyright

59 For Technical Assistance and Sales Contact: FlexEJ Ltd Tel: +44 (0) Fax: +44 (0) Web: Section 4 Expansion Joints - Installation Instructions Pre-Installation Checks and Precautions FlexEJ Expansion Joints are fully inspected at the factory and are packaged to arrive at the job site in good condition. Please, immediately upon receipt at the job site, verify that there is no freight damage; i.e., dents, broken hardware, loose shipping bars, etc. Because the bellows expansion joint is required to absorb thermal and/or mechanical movements, the bellows element must be constructed of a relatively thin material. This requires special installation precautions. The following steps should be taken prior to installation of the expansion joint into the pipeline or duct. 1. The opening into which the expansion joint will be installed should be examined to verify that the opening for which the expansion joint was designed does not exceed the installation tolerances designated by the designer and/or purchaser. If the opening exceeds the tolerance, notify FlexEJ at once for a disposition. 2. The attachment edges of the pipe or duct should be smooth, clean, and parallel to each other. 3. The area around the expansion joint should be cleared of any sharp objects or protrusions. If not removable, they should be noted so they can be avoided. 4. Expansion joints provided with lifting lugs should be lifted only by the designated lifting lugs. SHIPPING BARS (PAINTED YELLOW) ARE NOT DESIGNED TO BE LIFTING DEVICES. NEVER USE A CHAIN OR ANY OTHER HANDLING DEVICES DIRECTLY ON THE BELLOWS ELEMENT OR BELLOWS COVER. For expansion joints not provided with lifting lugs (i.e. less than 200 Kgs) the best lifting method should be evaluated at the time of installation. 5. The shipping bars are installed on an expansion joint to maintain shipping length and give the expansion joint stability during transit and installation. DO NOT REMOVE THE SHIPPING BARS UNTIL THE INSTALLATION IS COMPLETE. Installation The unrestrained Axial Expansion Joint must only be used in straight line pipe runs that have been ADEQUATELY ANCHORED AND GUIDED. The Axial Expansion Joint may be positioned anywhere in a straight pipe run. However, the number of anchors, primary and intermediate guides required varies, so it is important to carefully assess the options available on site. When installing an expansion joint the following precautions must be taken: 1. Remove any protective covering from the ends of expansion joint. Plywood covers may have been used to protect flanges or weld ends. Check inside expansion joint for desiccant bags or any other material. 2. When a flow liner is installed in the expansion joint, orientate the expansion joint with FLOW ARROW POINTING IN DIRECTION OF FLOW. 3. When using lifting lugs, lift the joint to desired location and position into pipeline or ducting. 4. Weld/Soldered End Expansion Joints. 4.1PRIOR TO WELDING/SOLDERING, COVER THE BELLOWS ELEMENT WITH A CHLORIDE FREE FIRE RETARDANT CLOTH. This is to prevent arc strikes, weld splatter, etc. from damaging the bellows element. 4.2 Using the proper electrode/flux, weld the expansion joint to adjacent piping. DO NOT USE BELLOWS TO CORRECT FOR MISALIGNMENT OF PIPING UNLESS THIS HAS BEEN CONSIDERED IN THE DESIGN OF THE EXPANSION JOINT. 5. Flanged End Expansion Joints. 5.1 Orientate expansion joint flanges so that the bolt holes are aligned with the mating flanges. DO NOT FORCE THE EXPANSION JOINT TO MATCH THE BOLT HOLES OF THE MATING FLANGE. This causes torsion on the bellows and will severely reduce the bellows capability during operation and may cause premature failure of the expansion joint. It is good practice to leave one pipe flange loose until the expansion joint is installed or to purchase an expansion joint with a flange that will rotate. 5.2 Install gaskets and bolt to the required torque recommended by the flange manufacturer. 6. Union End Expansion Joints - Take great care when fitting screwed end expansion joints not to apply any torsion to the bellows. Expansion joints are damaged very easily when torque. Always use a full Union at both ends. FLEXEJ LIMITED WARRANTY IS VOID UNLESS THE ABOVE INSTRUCTIONS ARE FOLLOWED FlexEJ copyright

60 Expansion Joints - Installation Instructions Pipe Anchors & Guides Straight pipe runs when compensated by unrestrained axial expansion joints tend to buckle under the influence of both, the internal pressure acting on the bellows and/or the flexibility of the bellows itself. They can also buckle under the influence of the pressure thrust developed by the bellows, which loads the pipe axially and causes it to act like a straight beam subjected to compressing axial forces. Besides proper supporting of the pipeline for weight and external forces, it is of vital importance that the correct alignment of the pipe is maintained to ensure the proper functioning of the expansion joints. Using a proper guiding system, which shall follow the rules given below, can control the risk of buckling: Rule A: The piping system has to be sectionalised by means of fixed points, anchors and guides. Only one expansion joint must be fitted per section of straight line. Rule B: The pipe anchors and other restraining devices shall be designed for the full pressure thrust acting on the effective area of the bellows, plus the bellows spring reaction load. The friction loads generated by the type of guide/support should also be considered for each section of pipe between anchors. Axial expansion joints not restraining the pressure thrust L1< 4 D, L2<14 D Lf minimum possible Lg, the maximum distance between two guides at any conditions shall be limited to: Where: E, is the modulus of elasticity of the pipe material J, is the moment of inertia of the pipe cross section With the mean diameter, D 3 mp, of the pipe and, e, its wall thickness S, is the safety factor (recommended: S = 3) F i, is the buckling force consisting of the following components, which may act on the pipe simultaneously: Fi = Fp + FB + FF, Where: F p = p.a is the pressure thrust. The bellows effective area a is given in the FlexEJ data sheets. F B = ± X.K B is the axial displacement force generated by the bellows The axial displacement, X, of the expansion joint is measured from the neutral axis position. It is positive for compression and negative for extension. The spring rating, K B, is given in the FlexEJ data sheets. FF = ± µ.f N defines the friction forces in the pipe guide.

61 For Technical Assistance and Sales Contact: FlexEJ Ltd Tel: +44 (0) Fax: +44 (0) Web: Section 4 Expansion Joints - Installation Instructions All the singular forces bring by every guide between on a section of straight run have to be taken in consideration to calculate the friction axial force. These friction forces will occur when the system is moving, mainly when the temperature changes or for any other matter. The value of, µ, which is the friction coefficient in the guides and supports is given by the support manufacturer and the vertical load, FN, which are mainly weight loads are given by the pipe stress analysis. Rule C: When on the same straight pipe run, an axial expansion joint is located adjacent to a pipe reducer. The loads on the small diameter anchors will have to take into account the full pressure thrust of the expansion joint. Consideration should be made for eccentric pipe reducers and the effect of an offset load (l). Single axial expansion joint located on the large diameter side of a reducer Rule D: The pipe shall be guided in such a way that no lateral or angular movements allowed for in the pipe stress analysis or in the expansion joint design, can occur. For small diameters, the guides have to be spaced in such a way so that snake behaviour of the line can be avoided. To allow free straight movements of the pipe, the supporting devices of the system shall be designed to reduce the friction and the risk of binding in the guides. Single axial expansion joint on a pipe run containing an offset This application shall be avoided because the pressure thrust developed by the bellows and the friction forces due to the thermal expansion will introduce a moment in the piping, which may result in an overstressing of the piping and of the guides. Pipe Guide Spacing Table NOTES: FlexEJ recommends that for ABS, ABSC, ANW, ANF, ANL, UNW, UNF type Bellows Expansion Joints the first guide be located within four (4) pipe diameters from the expansion joint and the second guide be located within a distance of fourteen (14) pipe diameters from the first guide. The remaining guides are to be in accordance with the table below. The table on the next page shows the recommended MAXIMUM Spacing of Intermediate Pipe Guides for Applications Involving Axial Movement Only. (Values Based on Standard Weight of Carbon Steel Pipe.)

62 Expansion Joints - Installation Instructions For all other pipe sizes refer to the Standards of The Expansion Joint Manufacturers Association. After Installation But Prior To The Hydro Test Pre-Test Checks 1. Inspect entire system to insure that anchors, guides and pipe supports are installed in strict accordance with piping system drawings. A pipe guide spacing chart is provided on the previous page to aid in this check. 2. ANCHORS MUST BE DESIGNED FOR THE TEST PRESSURE THRUST LOADS. Expansion joints exert a force equal to the test pressure times the effective Area of the bellows during hydro test. Pressure thrust at design pressure may be found on the individual drawings. Refer to EJMA Safety Recommendations. 3. If the system media is gaseous, check to determine if the piping and/or the expansion joint may require additional temporary supports due to the weight of water during testing. 4. REMOVE SHIPPING BARS (PAINTED YELLOW) PRIOR TO HYDROTESTING. Shipping bars are not designed for hydrostatic pressure thrust loads. 5. Hydrostatically test pipeline and expansion joint. ONLY CHLORIDE FREE WATER SHOULD BE USED FOR HYDROTEST (published reports indicate chloride attack as low as 3 PPM). Water should not be left standing in the bellows. General Precautions 1. Cleaning agents, soaps and solvents may contain chlorides, caustics, or sulfides and can cause stress corrosion which appears only after a bellows is put into service. 2. Wire brushes, steel wool and other abrasives should not be used on the bellows element. 3. Hydrostatic test pressure should not exceed 1.5 times the rated working pressure unless the expansion joint was specifically designed for this test pressure. 4. Some types of insulation leach chlorides when wet. Only chloride free insulation materials should be used for insulating an expansion joint.

69 For Technical Assistance and Sales Contact: FlexEJ Ltd Tel: +44 (0) Fax: +44 (0) Web: Section 6 METAL HOSE DESIGN Influence of the service conditions on the metal hose design In view of the wide variety of potential applications the working pressures and bending radius stated in the technical tables can only be used as a guideline. They are valid for predominantly static stress and room temperature (20 C). The bursting pressure of the hoses is a factor of 4X greater than the working pressure stated in the tables. The maximum allowable testing pressure is 1.5X the working pressure. The actual service conditions (i.e. pulsating and discontinuous demand, type and frequency of motion, higher working temperature etc) exert additional demands on the hose material. These influences must be taken into account when determining the safe working and working life of the hose assemblies using the tables and formulae given here. Single motion Minimum bending radius for single motion tested according to ISO picture 2. Repeated motion For repeated motion without major dynamic demand. Dynamic motion For dynamic motion the radius Rb is to be re-calculated according to the table with the help of the corrective factors ft and fdyn. The allowed working pressure is calculated as follows: P toel. = Allowed (bar) working pressure P max = Max. working (bar) pressure acc. to table f t = Reduction factor for (without dimensions) increased temperature f dyn. = Reduction factor for (without dimensions) dynamic demand The allowed bending radius is calculated as follows: R dyn. = R b ( 1,09 + f t.f dyn ) 2,98 f t f dyn.

73 For Technical Assistance and Sales Contact: FlexEJ Ltd Tel: +44 (0) Fax: +44 (0) Web: Section 6 Metallic Flexible Corrugated Hose Assemblies Installation & Safety Guides FlexEJ metallic flexible corrugated hose assemblies are designed to meet pre-defined parameters of maximum operating conditions. It is therefore important to ensure the flexible hose assembly meets the intended service conditions. Prior to placing a metallic flexible hose assembly in to service, as a minimum, consideration should be given to ensuring the flexible hose assembly will meet all aspects of the application, in respect of pressure, temperature, materials compatible with intended service, bend radius requirement, flow velocity, end fitting specification and end fitting attachment method. The known integrity of the flexible hose assembly is important to the safety of any application. If in doubt ask. Pressure: Flexible metallic hose assemblies must not be used above their maximum design pressure. Shock pressure: Pulsating, surge or shock pressure will affect the life of a flexible hose assembly. Such pressure conditions must not exceed 50% of the flexible hose assembly maximum rated design pressure. Temperature: Metallic flexible corrugated hose assemblies generally provide a good design temperature range. FlexEJ stated maximum design pressures with weld (TIG) attached end fittings are based on ambient temperature condition. When using flexible metallic hose assemblies at temperatures above ambient condition it is important to take into consideration pressure/temperature de-rating factors See Appendix Bend radius: Care should be taken to ensure the flexible hose assembly is not installed and working with a bend radius below its published minimum design bend radius. Published minimum bend radius figures cover both static and flexing installations. Failure to consider this can result in fatigue and premature failure. Avoid installations resulting in sharp bending immediately behind the flexible hose end fitting. Flow Velocity: High velocities can lead to premature fatigue failure of a corrugated flexible hose assembly. A metallic stripwound interlocking liner should be considered and introduced if flow velocity exceeds:- Flexible corrugated hose assembly without external braid reinforcement if gas flow exceeds 30 metres/second or in the case of liquid 15 metres/second Flexible corrugated hose assembly with external braid reinforcement if gas flow exceeds 45 metres/second or in the case of liquid 22.5 metres/second When a hose assembly is installed in a bend, these values should be reduced by 50% for a 90 degree bend, 25% for a 45 degree bend and appropriately in proportion to the angle of bend. With higher velocity the next larger bore size should be used with a stripwound liner End Fitting Specification: Selection of the correct specification of end fitting is important to a safe application. The end fitting should be suitable for the extremes of pressure and temperature. End Fitting attachment: Ensure the end fitting attachment method is compatible with the application, particular the operating temperature. Most metallic flexible corrugated hose assemblies employ weld (TIG) attachment which will perform at the higher temperature range but other attachments are used, such as, brazing (silver solder) which have limitation on temperature performance. Do not Torque: Flexible metallic corrugated hose assemblies must never be subjected to torque or twisting during installation and application. To avoid this condition during installation use as a minimum a swivel end fitting at one end of the flexible hose. The fixed end should always be connected first. For movement applications always install the flexible hose assembly so the movement occurs in one plane only, and in the plane of bending. Failure to apply these rules will result in premature failure. FlexEJ copyright

74 METALLIC FLEXIBLE CORRUGATED HOSE ASSEMBLIES INSTALLATION & SAFETY GUIDES Axial movement: Flexible corrugated hose assemblies are not designed for in-line axial movement and should not be subjected to compression or extension during application service. Abrasion/rubbing: Do not allow flexible corrugated hose assemblies to rub on other objects or equipment. This can be particularly damaging if the hose assembly is installed on a flexing application or being used for vibration movement. Premature and catastrophic failure can occur especially if the pressure restraining braid is damaged and weakened. Corrosion: Correct selection of materials is important when considering flexible corrugated hose assemblies for transferring chemicals or if used in a chemical environment. Metallic flexible corrugated hose assemblies produced of commercial grade stainless steel materials, including 316L are not suitable for transferring seawater or seawater contact. Premature failure caused by pitting corrosion or fatigue cracking of the corrugated flexible tube will occur. Refer attached illustration guide for correct installation recommendations. Maintenance, inspection and testing: Having placed in to service a well designed, manufactured and tested flexible hose assembly, consideration should be given to on-going maintenance, inspection and testing. Depending upon the severity of the application the life expectancy of a flexible hose assembly will be effected. Users should ensure all flexible hose assemblies are subject to periodic inspection. As a minimum this should include a regular periodic visual inspection to check for any wear or damage to the flexible hose that may affect its continuing service. Re-testing of hose assemblies is recommended at least annually. The test pressure should be 1.5 times the maximum working or design pressure. When used in arduous or safety critical applications a planned maintenance replacement programme is recommended.

Air Release Valve Installing & Maintaining Your Dosing Pot It is important that the dosing pot is correctly attached to the system to allow rapid chemical feed. Choose a location near a main pipe run or system header. Fasten the chemical dosing pot securely in place using the brackets attached to the back of the steel body. Pipe the drain valve away to a safe disposal point. It is best to connect to the system across the flow and return pipe work. The flow connection should be made to the appropriately named Flow Valve at the bottom of the pot and the return connection made to the appropriately named Return Valve. For all working conditions please refer to the data sheet provided. The Dosing Pot should not be operated outside of these limits. After long term use the valves may wear. They should be inspected periodically and if necessary replaced. The Dosing Pot itself should also be checked periodically for corrosion and other wear. A 1mm corrosion allowance has been incorporated into the design. If corrosion is found to be greater than 1mm the pot should be removed and replaced. A non return valve is fitted below the filling valve to prevent blow back occurring. The Dosing Pot could reach temperatures of up to 110 o c. PPE appropriate for the working temperature and chemicals being used must be worn. Hazard Warnings should be fitted at the installation location and be visible to the operator in order to prevent the operator from causing harm to themselves or others. FlexEJ copyright
