1.0 Introduction Metallic expansion joints are installed in piping systems to absorb differential thermal expansion and vibration whilst containing the system pressure. They are a highly engineered product that needs to conform to one of the industry codes such as EJMA or AD Merkblatt. Under the guidance of these codes, James Walker Townson offers a complete range of Comflex metallic expansion joints together with the ability to design joints to individual customer requirements. They can be customised to any dimensions, both circular and rectangular. Manufacturing partnership Comflex metallic expansion joints are provided in partnership with Đuro Đakovic - Kompenzatori of Slavonski Brod, Croatia, who manufacture them for James Walker Townson. Typical applications for metallic expansion joints include petrochemical plant, refineries, power stations, district heating installations, HVAC systems etc and wherever piping systems or ducts are subjected to movement through the effects of temperature, pressure or external forces. Built for reliability In theory, bellows are one of the most sensitive components of the pipework installation, with thin gauge metal having to withstand the same extremes of temperature and pressure as the pipework installation to which it is fitted. Yet today, modern expansion joints are considered a permanent part of a pipework installation. Metallic expansion joints require special attention when considering product type, materials of construction, location within the system, anchors, guides and end loads. To ensure customer satisfaction, James Walker Townson s technical support team offers a full design service and on-site technical support to make sure all these conditions are met. Meeting customer requirements This brochure is intended to give technical advice on the design and installation of expansion joints in general as well as technical details of the Comflex range of metallic joints. James Walker Townson engineers will be pleased to advise on the application and installation of expansion joints to meet customers particular requirements.

2.0 Manufacturing methods The basic method of bellows manufacture is not complicated, and every bellows manufacturer forms his bellows convolutions in one of two ways: either by mechanical forming, or by hydraulic forming. The principle is the same for both. First of all a sheet of suitable material (usually stainless steel) is selected, cut, rolled to the correct size and welded longitudinally. The quality of this weld prior to convolution forming is of paramount importance to bellows life. Recognising this, we have developed our own automatic welding machines which are an engineering achievement in their own right. These machines produce a weld which is as strong as the parent metal, but does not thicken the material. Absence of either factor could seriously affect bellows life. The next stage is to form convolutions. This can be done either by roll-forming the convolutions between external and internal wheels, or by forcing the tube radially under hydraulic pressure into required convolution profile. Bellows with reinforcing rings These can have reinforcing rings fitted into the convolution roots to improve pressure resistance and movement requirements. An example is shown in Fig. 1. Fig. 1. Bellows convolutions with reinforcing rings Multi-ply bellows An important development in the design of bellows was the introduction of more than one ply of metal in each construction. It was discovered that by making bellows plies of thin-gauge metal rather than from one sheet of thicker gauge stock, flexibility and stress loading through movement could be extended further up the pressure range. Multi-ply bellows are a standard feature of our designs. Fig. 2. Fig. 2.

3.0 Glossary of terms Backing Ring Cylinder attached to cuff to provide reinforcement. Bellows Cuff Plain cylindrical end of bellows extending beyond convolutions. Bellows Element The flexible membrane of a bellows unit, consisting of one or more convolutions. Centre Pipe or Tube A length of pipe connecting the bellows elements to form a double bellows unit, the length of which is critical to the stability of the assembly. Cold Pull-up or Cold Draw Extension of bellows from free length so that maximum movement of bellows can be utilised. Convolution The smallest flexible unit of a bellows. The total movement of a bellows being proportional to the number of convolutions. Directional Anchor A directional anchor, or sliding anchor is one which is designed to absorb loading in one direction while permitting motion in another. It may be either a main or intermediate anchor, depending upon the application considered. When designed for the purpose, a directional anchor may also function as a pipe guide. When designing a directional anchor, an effort should be made to minimise the friction between its moving or sliding parts, since this will reduce the loading on the pipe and equipment and ensure correct functioning of the anchor. Directional Pipe Guide A directional pipe guide is a pipe alignment guide designed to permit the pipeline to move freely in one plane with a limited movement, in another plane. This type of guide is used in applications involving movements in more than one plane as in a 3 pin configuration. Expansion Joint A device containing one or more bellows elements used to absorb movements such as those caused by thermal expansion or contraction of a pipe line duct, or vessel. Flanged Ends The ends of a bellows unit equipped with s for the purpose of bolting the unit to the mating s of adjacent piping or equipment. Free Length The natural length of the assembly without cold pull or lateral offset. Hinge Restraints Fabricated assembly on single and double hinged or gimbal bellows unit which allows the bellows to angulate and containing the effect of pressure within the unit. Intermediate Anchor An intermediate anchor is one which divides a pipeline into individual expanding pipe sections. Such an anchor must be designed to withstand the forces and moments imposed upon it by each of the pipe sections to which it is attached. In the case of a pipe section containing a bellows these will consist of the forces and/or moments required to deflect the bellows unit plus the friction forces due to the pipe moving over its guides. The pressure thrust is absorbed by the main anchors or devices on the bellows unit such as limit rods, tie rods, hinge restraints, gimbal restraints etc. Internal Sleeve A device which minimises the detrimental effect of media flow through the expansion joint. Lateral Offset Is the lateral, or shear, pre-setting of one connection to the other to enable the maximum movement to be obtained from the bellows unit. Life Cycles This is the number of complete expansions and contractions an expansion joint can accoodate within its theoretical working life. Limit Stops or Tie Rods Devices used to restrict the range of movement of a bellows unit or its component parts. Various designs such as rods, bars or sliding stops may be used. It should be noted that to function properly as limit stops these devices must be designed for full pressure loading, unless the load is absorbed by other structural devices. External Shroud A device used to protect the external surface of the bellows from damage by foreign objects or mechanical damage.

3.0 Glossary of terms Main Anchor A main anchor is one installed at any of the following locations in a pipe system containing one or more bellows: 1. At a change in direction of flow 2. Between two bellows units of different size installed in the same straight run. 3. At the entrance of a side branch into the main line if this branch contains a bellows. 4. Where a shut-off or pressure-reducing valve is installed in a pipe run between two bellows units. 5. At a blind end of pipe. A main anchor must be designed to withstand the forces and moments imposed upon it by each of the pipe sections to which it is attached. In the case of a pipe section containing an unrestrained bellows these will consist of the thrust due to pressure, the force required to deflect the bellows unit and the frictional force due to the pipe moving over its guides. Where a main anchor is installed at a change of direction of flow, the effect at the bend of the centrifugal thrust due to flow must be considered. Movement Axial Compression. The dimensional shortening of a bellows unit parallel to its longitudinal axis. Axial Extension. The dimensional lengthening of a bellows unit parallel to its longitudinal axis. Lateral Deflection. The relative displacement of the two ends of a bellows unit perpendicular to its longitudinal axis. This is sometimes referred to as lateral off-set, lateral movements, parallel misalignment, direct shear, etc. Angular Rotation. The angular displacement of one bellows connecting face relative to the other from its straight line position. This is, not to be confused with torsional rotation about the longitudinal axis which must be avoided. Sometimes known as rotational or radial movement. Restraining Ring A device which fits closely into the crest or root of a convolution to reinforce the bellows against the effects of either internal or external pressure. Restraining rings are manufactured from solid round bar or heavy gauge tube in stainless steel or other suitable alloys. Spring Rate The force required to extend or compress the bellows unit length. Stability The ability of a bellows to withstand internal pressure without distortion of the convolutions. This is sometimes known as squirm and can be compared with strut instability of long thin columns. Tie Rods Rods or bars for the purpose of restraining the bellows unit from the pressure thrust due to internal pressure and other internal applied forces. Tie rods may also act as limit stops when provided with the necessary stops. Weld Ends The ends of a bellows unit equipped with pipe suitably bevelled for welding to adjacent piping or equipment. Multi-ply A bellows constructed from a multiple of tubes fitting closely inside each other. Pipe Alignment Guide A pipe alignment guide is a form of sleeve or framework attached to some rigid part of the installation which permits the pipeline to move freely in only one direction, i.e. along the axis of the pipe. Pipe alignment guides are designed primarily for use in applications involving axial movement only. Pressure Thrust or End Load The force due to internal or external pressure acting on the bellows trying to extend or compress the bellows. 6 To order or get further details, call your local contact shown on rear cover or listed at www.jameswalker.biz

4.0 Technical information Expansion compensation of pipes subject to movement due to the effects of temperature, pressure, and external sources has for many years been carried out in various ways. Primarily the most effective method is to use the inherent natural flexibility of the pipework system utilising bends etc. to form natural loops. When stress levels either within the pipes or at vessel connections become too great other means of compensation are employed, namely the made up loop and the sliding joint. Examples of which are illustrated in Fig. 3. 4.1.1 Pressure The design of a bellows element being partly dependent on the pressure applied to the pipeline, either negative or positive. It is important to know the design, working and test pressures to which the bellows will be subjected. Normally the element is designed for operation at the higher of either the design or operating pressure except where a test condition is required which exceeds 1.5 times these conditions. In this situation a bellows having a higher pressure rating must be used. Fig. 4. shows the effect of pressure acting upon the bellows convolutions trying to open the bellows both longitudinally and circumferentially. Fig. 3. Typical made-up expansion loop and sliding joint Expansion loops apart from being expensive in material and wasteful of space, are restricted by the stress limits of pipe under bending. Packed sliding joints, which operate on the principle of the simple telescope are vulnerable to scaling problems and require constant maintenance. The limitations of these two systems led to the development of fabricated bellows. These were essentially thick wall bellows, in effect dished plates welded together circumferentially to form a series of convolutions. Heavy gauge metal is used (hence the Thick Wall description) and considerable force is required to induce movement. To overcome this problem it was discovered that by careful cold-rolling of a thin gauge tube a bellows could be formed and could be compressed or extended without exerting undue strain on the material or creating unacceptable counter forces acting against the pipe anchors. Thus thin wall bellows were evolved to meet the requirements of piping system and subsequent development has led to the universal acceptance of these bellows as permanent component part of a complete piping system. This section of the publication deals with the manufacture performance and selection of the appropriate expansion joint to suit particular applications. 4.1 Variables to be considered When selecting an expansion joint the following variables must be considered. 1. Pressure-working, design and test. 2. Temperature-working and design. 3. Media flowing through the pipe. 4. Pipework system. 5. Movements to be applied to the expansion joint. 6. Type of expansion joint. 7. Life cycles. Fig. 4. Effect of internal pressure on a bellows unit 4.1.2 Temperature Table Temperature 1.

For higher temperatures we have to choose bellows for higher nominal pressure at the base of t k. This factor generally is responsible for the pipeline movement This factor generally is responsible for the pipeline and again both working and design conditions must be considered. It is also important to assess the effects of installation conditions in some circumstances, in particular in sub zero climates for cryogenic applications and the use of cold-pull up should be employed. 4.1.3 Media Standard ranges of bellows are manufactured in 18/8 stainless steel which is suitable for a large number of conditions but it should be borne in mind that for applications where a corrosive media is present bellows are available in other materials. 4.1.4. Pipework System The pipeline layout and the positions of major items of equipment will already be established and from this point it is possible to establish anchor positions and hence the expansions of the various sections of pipework.

4.0 Technical information 4.1.5 Movement It is always important to remember that a bellows is a living device and changes shape as a result of the forces applied to it. Bellows movement can always be expressed quantitatively, axially, laterally or angularity and from known factors of temperature and thermal coefficients of expansion of pipe material it is a straight-forward exercise to calculate the movements to be absorbed by the bellows. Fig. 5. shows how a simple axial bellows moves in and out as the anchored pipeline expands and contracts with temperature changes, while Fig. 6. shows how an articulated bellows joint allows the expanding pipework to move out of line without straining pipework supports and items of equipment. Pipe contracting Pipe expanding anchor Fig. 5. The operation of an axial bellows Movement caused by external physical force must also be considered as in some instances this can be the primary source of movement. e. g. long lengths of pipework installed along the deck of a ship is subject to the hogging and sagging of the deck. Bellows are installed to take up this movement in addition to the thermal expansion of the pipeline. Fig. 6. The operation of hinged units Vibration in pipework caused by compressors, pumps, or other in-line equipment can be counteracted and in some instances bellows are used where both vibration and thermal movements are present as in the case of movements at the nozzle of a turbine caused by machine vibrations and the thermal expansion of the hot turbine casing. For applications where vibration is present it is important to James Walker Townson to ensure that the correct bellows is specified. The following information is required: a. Frequency of vibration movement b. Amplitude c. Natural frequency of system (if known) 4.1.6 Expansion Joint Type As you can see from the tables within this brochure there are a great variety of types of expansion joints, each operating in its own individual way. When making an expansion joint type selection, the suitability of the joint for the overall system design must be considered. Expansion in a piping system can often be accoodated with several different combinations of expansion joint. The optimum solution can be affected by many issues: Financial restraints Access Suitability of steelwork to provide adequate support Pressure in the system Location of the piping relative to ground level or structures The configuration of the piping system Life cycle requirements etc... All these factors must be taken into consideration when designing a system, and the skill of a successful designer is incorporating all these issues to provide the optimum selection type. 4.1.7 Life Cycles The cyclic life expectancy of an expansion joint is affected by various factors such as: (a) operating pressure, (b) operating temperature, (c) the material from which the bellows is made, (d) movement per convolution, (e) thickness of the bellows, (f) convolution pitch, (g) depth and shape of the convolution, and (h) bellows heat treatment. Any change in these factors will result in a change in the life of the expansion joint. The cyclic life expectancy can be defined as the total number of complete cycles that can be expected from the expansion joint based on data tabulated from tests performed at room temperature under simulated operating conditions. A cycle is defined as one complete movement from the initial position in the piping system to the operating position under consideration and return. Expansion joints can be specially designed for very high cyclic life. However, when this is required, the expansion joint manufacturer must be advised of the estimated number of cycles required. Cyclic life is dependent upon the maximum range of stress to which the bellows is subjected, the maximum stress amplitude being a far less significant factor. Accordingly, in most cases, cold springing an expansion joint in order to reduce the maximum stress amplitude would not result in a significant improvement in cyclic life. 8 To order or get further details, call your local contact shown on rear cover or listed at www.jameswalker.biz

5.0 Expansion Joint Types Axial Bellows Code: AR They can be supplied with end prepared for welding into pipework. Having installed the unit into the pipeline it only remains for the set screw to be removed. See detailed description in "Special Applications" section. Externally Pressurised Axial Bellows Code: AE Axial bellows expansion joints are designed to accoodate compressive or extension movements along the bellows longitudinal axis. Movements available are usually specified as ± amounts from free length. The free length is the theoretical length before movement. From this free length the unit will provide an equal amount of movement in either extension or compression. Therefore, to utilise all the movement available from the unit when it is known that the movement will be in one direction only, it is recoended that the units are installed with either preextension or precompression, dependent upon the pipe movements. Care is required during installation to ensure that the unit is installed at its correct length so that it will only work within its specified limit. Any deviation would have a detrimental effect upon the bellows life. It should also be ensured that axial units are adequately anchored and guided. Axial bellows are supplied d or with pipe ends suitable for welding into pipelines, or as a combination of both. Applications where a combination of high pressure and long axial movements exist have resulted in the development of the externally pressurised unit. It can be seen that the working pressure is transferred to the outside of the bellows via a gap between the rolled and welded section and the pipe. The unit is completed by a purpose-made outer casing which contains the working pressure. United Double Bellows Code: UD Self Guided Axial Bellows Code: AS Experience has shown that there is a need for a special type of unit for use by the heating and ventilating trade. As can be seen from the above diagram these units have an internal sleeve and an external shroud which makes it impossible to install them into pipework which is initially misaligned. In addition to being practical the shroud also gives the Self Guided Axial a pleasing streamlined appearance. The units are supplied at their extended length and held at this length by a small set screw. This ensures that they are at all times installed at their correct length which in turn ensures a life-time of trouble free operation. The internal sleeve gives a smooth flow of the water through the unit and the direction of flow is clearly indicated on the outer shroud. A double bellows assembly is formed by connecting two bellows with a length of centre pipe. This type of unit will cater for both axial and lateral movements. Although a conventional axial bellows will offer a limited amount of lateral movement it is usually advisable for a double unit to be used if the amount of lateral movement required is significant or there is a limitation to the amount of lateral forces which can be applied to the connecting pipework. This type of unit is ideal for some exhaust applications or where there are combination movements in low pressure applications.

5.0 Expansion Joint Types Tied Bellows Code: TD (two bar), TM (multi bar) Gimbal Bellows Code: GS For higher pressure applications where there are limits to the forces that connecting pipework can accoodate, double units are restrained against pressure load by the use of tie bars. These are designed to contain the pressure load within the unit length and do not transmit this load to the adjacent pipework. The tie bars are connected to the restraining s through spherical washers which allow for movement between the tie bars and the s during operation. This type of unit can accoodate large movements in the lateral plane and can operate in any direction. Provided there are no more than two tie bars, they can also accoodate angulation movements of the s. The amount of lateral movement is dependent upon the unit s length. Gimbal Bellows are designed to allow angular rotation in any plane using two pairs of hinges fixed to a coon floating gimbal ring. The gimbal ring and hinged parts are designed to restrain the end thrust of the expansion joint due to internal pressure and any external forces which are imposed on the joint. As in the case of Single Hinged Bellows, Gimbal Bellows are usually used in pairs. Pressure Balanced Bellows Code: PB Single Hinged Bellows Code: HS Hinged units offer movements in one plane only and operate by angulating the bellows. The pressure load is contained by the hinges and therefore this type of assembly is ideal where it not practical to install robust guiding or strong anchors. Single Hinged Bellows are usually used in pairs to give lateral movement in one plane. Double Hinged Bellows Code: HD One of the major problems to overcome when using expansion bellows with a combination of large diameters and high pressure is that these units must be adequately guided and anchored. There are, however, certain conditions where it is not practical to install anchors; e.g. on a plant where space is at a premium, and also where equipment such as pumps, turbines or valve connections has a limitation to the forces which may be exerted on s (which are very often integral castings of the plant casting). Also, when movements of the pipework and plant are in more than one plane, this can prove to be a major problem. The problem of pressure loads can be overcome by the use of pressure balanced bellows units. There are a variety of arrangements but in every case the object is to eliminate the effect of pressure loads by arranging bellows so that two pressure loads - which are equal but act in opposite directions - cancel each other out, which results in the plant only having to accoodate the values of spring rates. These are relatively small when compared with pressure loads and are usually within loading limitations. Double Hinged Bellows are basically two Single Hinged Bellows combined into one unit with a coon tie bar joining the two extremities. Therefore, any expansion of the centre pipe within the limits of the tie bar will simply compress the bellows, and will not exert movements on the adjoining pipework. This type of unit allows for lateral movement in one plane only. 10 To order or get further details, call your local contact shown on rear cover or listed at www.jameswalker.biz

5.0 Expansion Joint Types Mount-demount Expansion Joints Code DK One of the most coonly used pressure balance bellows is shown in the diagram. In this case the effects of line pressure is balanced by allowing the pressure to pass, via a hole in the back of the bend, into a sealed outboard section of the same effective area as the line. By tying the unit over the extremities of the bellows, balance is obtained. When one bellows is compressed due to axial movement of the pipework, so the other is extended by the same amount due to the pressure end load acting on the blank end plate. The tie bar is always in contact with the support s, and therefore at all time the pressure load is contained within the unit itself. In addition it is possible to have pressure balanced units suitable for axial movement only. Also, where it is not convenient to have a bend or elbow in the pipeline, special units can be designed. Mount-demount expansion joints are often installed when a piece of equipment is to be removed regularly, such as a valve. The expansion joint is compressed allowing additional clearance (for the equipment to be removed and replaced). In our standard manufacturing program we have diameters from NB up to NB 0, for pressures 10, 16, 25 and 40 bar. On special request other diameters from NB 15 up to NB 5000 can be supplied. Max-comp Bellows Code: MC Max Comp bellows are designed particularly for use in polyurethane pre-insulated main pipeworks. The unit is a fully enclosed and protected expansion device which can be easily installed into pipework, without the usual need to cold-pull or extend the bellows.

6.0 Special Applications Heat Exchangers and Condensers Axial bellows are used to cater for the differential expansion between tubes and shell in fixed head and floating head heat exchangers. In the case of the fixed head type, the bellows are designed for shell side conditions. (see Fig.7) With floating head heat exchangers the bellows are designed for shell and tube side conditions independently. (see Fig.8) Bellows - Valve s Seals In this application, a bellows seal is used in place of conventional packing where the seal must be absolutely leakproof; for example, in nuclear installations. The necessary movement is taken up in the convolutions of the bellows. Fig. 7. Fixed head heat exchanger Fig. 9. Bellows - valves seal Fig. 8. Floating head heat exchanger Ship Deck Services and Product Lines For this application, in the majority of cases axial bellows are used to provide expansion compensation for pipelines providing the following services on tankers and bulk carriers: steam, condensate, deck wash, fire fighting foam, hot and cold tank washing, compressed air, and on liquefied natural gas (LNG) tankers, product suction and discharge. In this application the bellows have not only to be designed to cater for thermal expansion of the pipe runs but also for any additional movement due to hagging and sagging of ship generally specified in terms of extension and compression for an infinite cycle life under varying service conditions. Also in this application, because of the effects of corrosion precipitated by salt water spraying onto the outer surface of the bellows, care should be taken in the selection of bellows material.

6.0 Special Applications Rectangular Bellows (PK) Rectangular bellows (PK) are not standardised in our data sheet and therefore they are manufactured according to customer specifications. The biggest dimensions are limited only by transport possibilities, however this problem can be solved by making the rectangular bellows in sections and assembling at site. Rectangular bellows are made of convolutions with a height of and thickness approximately 1. Fig. 11.

6.0 Special Applications 1. Expansion joints for central heating Type AS James Walker Townson expansion joints represent a new stage in the development of bellow devices to absorb expansion in steam and hot water piping. They offer to a very high degree a combination of economy, simple installation and reliable service. By the use of high performance materials and exclusive manufacturing techniques James Walker Townson have produced a range of expansion joints which are maintenance free and virtually as permanent as the piping system in which they are installed. Specification Bellows: Made from ASTM A 240/A 240M UNS S32(321) stainless steel. Conservatively rated for a working pressure of 1 MPa (10 bar) at C, and hydraulically tested to 1.5 MPa (15 bar). Casing and other components of mild steel. Inner sleeve: Attached at one end and guided at the other, thus preventing off-set movement being transmitted to the bellows full length sleeve for minimum internal friction. Installation pin: Holds bellows at correct length for installation. Removed after fitting, and after guides and anchors have been installed. End fittings: Welding ends, s or threaded unions. Movement: Expansion joints allow axial movement of. Installation of expansion joints for central heating Anchors: The pressure thrust acting on the bellows must be absorbed by rigid anchors. Fig. 14. Expansion joints for central heating A number of features contribute to the reliability of these expansion joints. One is the uniformity of the stainless steel bellows, made under strict quality control supervision. Another is the full length inner sleeve which directs pipe movement squarely into the bellows, preventing offset movement being applied to the bellows, thus avoiding undue stresses. This inner sleeve also provides for a smooth flow and reduces pressure drop to a minimum. A third is the robust external casing which protects the bellows and ensures that pipe movement is applied axially. This method of construction allows them to be completely lagged without interfering with the bellows action. James Walker Townson expansion joints are available with a choice of end fittings - either pipe ends, s or threaded unions. Each individual expansion joint is hydraulically tested to one-and-a-half times its rated working pressure before despatch. For the actual installation it is simply necessary to fit the expansion joint into the pipeline and then remove an installation pin. This installation pin holds the expansion joint at its optimum length for installation and also protects the bellows from torsional damage installation. Note: Anchors must be designed to withstand test pressure being applied to the system. Main anchors should be located at branches and locations at which either the size or direction of the line changes. In addition, intermediate anchors should be used to break up straight runs to limit expansion in each section to. Guides: The expansion joint and attached piping must be guided axially to limit any lateral movement which would reduce the life of the bellows. Guides should be at least as long as two pipe diameters with the clearance between pipe and guide not more than 1,5. In locating guides it is recoended that the expansion joint be located close to an anchor and that the first pipe guide be located within a distance of two pipe diameters from the expansion joint. The distance between the first pipe guide and the second must be no more than fourteen pipe diameters. 14 To order or get further details, call your local contact shown on rear cover or listed at www.jameswalker.biz

6.0 Special Applications 2. Max-comp expansion joints Type MC Installation The unit is cold pulled to maximum length prior to dispatch by means of the pre-tensioning bolts. When the unit is installed by pre-insulated pipe manufactures these pre-tensioned bolts may be left in position and they are designed to break off when the pipeline is heated to operating temperature. There is no danger to personnel as the broken bolts are contained within the insulation. The bolt breaking load must be considered in the anchor design when the pre-tensioning bolts are left in position. For recoendations for anchor designs, please contact James Walker Townson. Where the pipeline is open and the pretensioning bolts are not adequately covered, it is advisable to remove them prior to coissioning the pipeline and after the anchors and guides have been installed. Fig. 15. Max-comp expansion joint Recoended pipe alignment guide spacing for standard steel pipes User advantages 1. The unit is supplied with pipe ends prepared for welding. 2. A robust outer cover ensures that the convolutions are fully protected against damage in transit or on site. 3. The outer cover also acts as a guide tube in which a guide ring welded to one pipe end is free to slide. This inbuilt guide assembly prevents any lateral forces being imposed on the convolutions. If the installation temperature is higher than the minimum anticipated line temperature it will be necessary to adjust the installation length by means of the pre-tensioning bolts. Guiding All axial expansion joints should be adequately guided in accordance with recoendations prior to pressure testing the pipeline. On each side of the Max-Comp the pipe should be provided with a guide at a max. distance from the Max- Comp equal to 18 times the pipe diameter. Where Max- Comp units are installed in pre-insulated pipelines guides, other than those incorporated in the pipe system, are not necessary. However it is essential to back-fill the pipe trench prior to pressure testing the pipe line. 4. Guide pins are incorporated in the guide ring which move in linear slots machined in the outer guide cover. These pins act as stops and limit the travel of the expansion joint both in compression and extension. Thus it is impossible to disengage the telescopic sleeves due to over extension of the unit during installation. 5. Two Max-Comp expansion joints may be installed in a straight length of pipe between two anchors without an intermediate anchor between the units. The movement stops ensure even allocation of total pipe movement between the Max-Comp units. 6. The guide pins also prevent torsion being applied to the convolutions during installation on site. 7. The guide pins are designed to retain the pressure end load. In the event of an anchor failure the expansion joint will simply extend to its maximum permitted movement within the limit of the guide pin slots. Fig. 16.

7.0 Material Selections For the large majority of applications involving thin wall bellows, stainless steel ASTM A 240/A 240M UNS S32(321) is used. It is only in exceptional circumstances that an alternative material needs to be considered. However, where exceptions do occur they must never be overlooked, as the effects of both media and external environmental conditions can cause a bellows unit to fail prematurely in operation if the material is not sufficiently resistant. The following notes refer to the most coon service conditions where care in the selection of bellows material must be exercised. Steam For the majority of steam applications the use of 18/8 stainless steel gives satisfactory service life. In some applications Chlorides may be present in such quantity that there is risk of failure of stainless steel bellows due to stress corrosion. Similarly, in some high temperature steam services, where conditions are highly alkaline, there may be risk of failure due to Caustic stress corrosion. In these cases the use of lncoloy 825 or other high Nickel alloy may be necessary. Marine Services Stainless Steel (BS) EN 88-2-1.4401 has been shown to give satisfactory service in general marine use, including pipelines carrying sea water (for example tank washing aboard oil tankers), where pipework is exposed to sea water spray, and in general where temperatures do not exceed 80 C. However, under ambient conditions, where for example crude oil or sea water remains static in the convolutions for prolonged periods, Type 316 material may sometimes fail. Also, where the pipework operates at temperatures in excess of 80 C - for example steam services - and where there is prolonged contact with sea water either inside or outside the bellows, Alloy 825 (UNS N 08825) can be used. Flue Gases Where flue gases contain such constituents as Sulphur Dioxide - for example, from boilers burning oil containing Sulphur - problems can arise if the temperature falls bellow the Sulphuric Acid dew point. Lagging should be used to prevent this where possible. If there is any uncertainty on this point it is preferable to use Alloy 825 (UNS N 08825). Diesel Engine Exhaust Manifolds Generally 18/9 Ti stainless steel is perfectly satisfactory, but where oils have a high Sulphur content or where very high temperatures are present, alternative materials should be considered. Hydrocarbon Lines Stainless steel is satisfactory for many Hydrocarbon lines, for some of the more arduous applications it is sometimes necessary to use an appropriate high Nickel alloy such as Alloy 825 (UNS N 08825). End Fittings It is often the case that bellows manufactured from one material are to be welded to an end fitting of another material. Through years of experience we have developed welding techniques that overcome this problem and supply joints that will provide years of reliable service. Crude Oil Lines For pipelines carrying crude oil - for example, discharge and suction lines to crude oil storage tanks - consideration must be given to the Sulphur or seawater content in the oil. In many cases, where the oil is reasonably pure, Type 316 stainless steel will give satisfactory service, but if the above impurities are present, Alloy 825 (UNS N 08825) provides better resistance towards pitting corrosion and is to be preferred. 16 To order or get further details, call your local contact shown on rear cover or listed at www.jameswalker.biz

Nr. 1.41/321 S31 č.72 Standard material for convolution and manufacture; adequate corrosion and mechanical properties at ambient and elevated temperatures for over 90% of all bellows applications. Standard units held in stock have convolutions in this grade of material. 2. ASTM A 240/A 240M UNS S 316(316Ti) 3. ASTM A 240/A 240M UNS S 400(4) W. Nr. 1.71/320S31 č.74 Improved corrosion resistance as compared to 321S31, especially with regard to pitting corrosion. Specified where 321S31 is inadequate but where conditions are not sufficiently severe to require the use of more expensive materials, such as high Nickel alloys. Typical uses include high Sulphur crude oils, brackish waters, flue gases and numerous applications in chemical and petrochemical processing. W. N r. 141/4S 1 1 č.80 Bellows can be supplied in this unstabilised grade where specially required but it is our normal practice to offer 321S31 as a superior alternative material where this grade is requested. 4. ASTM A 240/A 240M (310) 5. ASTM B 424 UNS N 08825 This grade is sometimes requested for special purposes. Because of difficulty in obtaining material suitable for bellows manufacture it is our practice to offer lncoloy 800 as a superior alternative material where necessary. W. Nr. 2.4858 A very useful high Nickel alloy having good corrosion resistance towards a variety of media, excellent resistance to Chloride and Caustic stress corrosion. Applications include steam service when the highest degree of reliability is required, and cases where Type 316S11 stainless steel may be inadequate, for example dewpoint conditions in flue gas service, static or contaminated sea water, and sulphuric and phosphoric acids. James Walker Townson maintain a substantial stock of this alloy for bellows manufacture. 6. ASTM B 409 UNS N 08810 7. ASTM B 168 UNS N 060 8. ASTM B 127 UNS N 04400 W. Nr. 1.4876 Bellows can be supplied in this material when its good corrosion resistance and high temperature properties are required to meet service conditions. The similar alloy Incoloy 800H can also be supplied for special service conditions at high temperatures. Incoloy 800 is preferred to Type 310 Stainless Steel for bellows manufacture. W. Nr. 2.4816 Bellow can be manufactured from this material when required. The alloy combines good general corrosion resistance with virtual iunity to Chloride stress corrosion and also has good high temperature strength and oxidation resistance. For high temperature service where corrosion resistance is not a requirement. Nimonic 75 is often preferable because of its superior mechanical properties. W. Nr. 2.43 This Nickel-Copper alloy finds limited use for bellows manufacture in some specialised applications; for example, Chlorine service. However, the manufacture of small diameter bellows would be uneconomic, and we advise that an alternative material should be used where the service conditions permit. 9. ASTM B 3 B2 UNS N 10665 W. Nr. 2.4617 This Nickel-Molybdenum alloy possesses outstanding resistance to Hydrochloric Acid, and is also resistant to Hydrogen Chloride gas and Sulphuric Acetic and Phosphoric acids. Bellows can be supplied when required, subject to the availability of sheet material. 10. ASTM B 443 UNS N 06625 W.

9.0 Instruction for the Installation and Inspection of Expansion Joints Installation The necessary steps for the installation of all expansion joints should be pre-planned. The installers shall be made aware of these steps. It is important that the joints are installed at the correct lengths and should not be extended or compressed to make-up deficiencies in pipe length, or offset to accoodate piping which has not been properly aligned. Any precompression or pre-extension of the joint should not be neglected if this has been specified. The most critical phases of the installation are as follows: a) Care should be taken to prevent damage to the thin wall bellows section, such as dents, scores, arc strikes and weld spatter. b) No movement of the joint due to pipe misalignment, for example, shall be imposed which has not been anticipated. If such movements are imposed, this can result in damage to the bellows or other components. Specifically the fatigue life can be substantially reduced, forces imposed on adjacent equipment may exceed their design limits, internal sleeve clearance may be adversely affected, and the pressure capacity and stability of the bellows may be reduced. c) Anchors, guide and pipe supports shall be installed in strict accordance with the piping system drawings. Any field variations may affect proper functioning of the joint and must be brought to the attention of a competent design authority. d) The joint, if provided with internal sleeves, shall be installed with the proper orientation with respect to flow direction. e) Once the anchors or other fixed points are installed and the piping is properly supported and guided, shipping devices should normally be removed in order to allow the joint to compensate for changes in ambient temperature during the remainder of the construction phase. Post Installation Inspection prior to System Pressure Test Careful inspection of the entire system shall be made with particular emphasis on the following: a) Are the anchors, guides and supports installed in accordance with the system drawing? b) Is the proper joint installed in the proper location? c) Are the joints flow direction and pre-positioning correct? d) Have all shipping devices been removed? e) If the system has been designed for gas, and it is to be tested with water, has provision been made for the support of the additional dead weight load? Some of the water may remain after test. If this is detrimental to the joint or the system, this should be removed before coissioning. f) Are all guides and supports free to permit pipe movement? g) Has any joint been damaged during handling or installation? h) Is any joint misaligned? i) Are the bellows and other moveable parts of the joint, free from foreign material? Inspection During and Iediately After System Pressure Tests. WARNING: Extreme care must be taken while inspecting any pressurised system or components. A visual inspection of the system shall include checking the following: a) Evidence of leakage or loss of pressure. b) Distortion or yielding of anchors, joint hardware, bellows element and other piping components. c) Any unanticipated movement of the system due to pressure. d) Any evidence of instability (squirm) in the bellows. e) The guides, joints and other moveable parts shall be inspected for binding. f) Any evidence of abnormality or damage shall be reviewed and evaluated by a competent design authority. Periodic Service Inspections a) lediately after placing the system in operation, a visual inspection shall be carried out to ensure that the thermal expansion is being absorbed by the joints in the manner for which they were designed. b) The bellows shall be inspected for evidence of unanticipated vibration. c) A prograe of periodic inspection shall be planned and conducted throughout the operating life of the system. These inspections shall include examination for evidence of external corrosion, loosening of threaded fastenings and deterioration of anchor guides and supports. This inspection prograe, without other information, cannot give evidence of fatigue, stress corrosion or general internal corrosion. Systems Operation A record should be maintained of change of system operating conditions (such as pressure, temperature, cycling, etc.) and piping modifications. Any such change shall be reviewed by a competent design authority to determine its effect on the performance of the joint, anchors, guides and pipework supports. 20 To order or get further details, call your local contact shown on rear cover or listed at www.jameswalker.biz

Whilst some fumes are emitted below C from fluoroelastomers or below C from PTFE, the effect at these temperatures is negligible. Care should be taken to avoid contaminating tobacco with particles of PTFE or fluoroelastomer, or with PTFE dispersion, which may remain on hands or clothing. Material Safety Data Sheets (MSDS) are available on request.
