INTRODUCTION
Thermal expansion in pipe lines, ducts, and vessels which carry hot or cold fluids, or which are exposed to large variations in ambient temperature, is a major problem confronting designers. As the metal temperature of the pipe, duct, or vessel increases or decreases, its length also varies due to thermal expansion or contraction. Therefore, unless compensation is provided for these dimensional changes, high stresses will be induced in the piping, ducting, or vessel and large forces will be transmitted through the system to anchors and connected equipment Several different methods are available for controlling thermal expansion of piping and ducting. Most designers prefer the use of metal bellows expansion joints because they require less space than pipe bends and expansion loops and their inherent flexibility enables them to absorb movements in more than one direction, thereby permitting greater freedom in design. Furthermore, in most pipe sizes, expansion joints are more economical than other devices such as bends and loops, so their use results in lower initial costs for piping and construction work. Operating costs are also reduced, since maintenance is eliminated and heat and friction losses are minimized. The need for expansion joints in vessels can sometimes be eliminated through careful design of their internal components, piping connections, supports and anchors. However, such a procedure is usually a costly one and imposes an unnecessary burden upon the designer. Here again, the use of expansion joints will almost always prove to be the simplest and most effective method of compensating for thermal expansion and contraction.

A-1 DEFINITION OF AN EXPANSION JOINT
For purposes oft his publication, the definition of an expansion joint is "any device containing one or more metal bellows used to absorb dimensional changes such as those caused by thermal expansion or contraction of a pipeline, duct, or vessel". A-2 EXPANSION DEVICES (Fig. A-1) In recent years, bellows expansion joints have largely replaced pipe loops and slip-type joints as the preferred method of absorbing movements in piping systems. Pipe loops are wasteful of both space and materials while the regular maintenance required by slip type joints makes them undesirable. Additionally, pipe loops and slip type joints have limited effectiveness since they are capable of absorbing only movement which is in-line with the pipe. Bellows expansion joints require no maintenance and are capable of absorbing many types of movement in a compact space.
A-3 DESIGN VARIABLES
If an expansion joint is to fulfil its intended function safely and reliably, it must be kept in mind that it is a highly specialised product. Interchange ability is rare in expansion joints, and in a real sense, each unit is custom-made for an intended application. It becomes necessary then, to supply the expansion joint manufacturer with accurate information regarding the conditions of design that the expansion joint will be subjected to in service. Because many of these design conditions interact with each other, designing a bellows becomes much like assembling a jigsaw puzzle; one needs all of the pieces (design conditions) before a clear picture of an expansion joint design can emerge. The following is a listing of the basic design conditions that should be supplied to the manufacturer when specifying an expansion joint: A-3.1.SIZE
Size refers to the diameter of the pipeline (or dimensions of the duct in the case of rectangular joints) into which the expansion joint is to be installed. The size of an expansion joint affects its pressure-retaining capabilities, as well as its ability to absorb certain types of movements.
NOTE: When specifying pipe sizes, misunderstandings often result due to the confusing array of nominal pipe sizes (NPs) and different pipe schedules. Eliminate any misconceptions, pipe sizes should be supplied to the expansion joint manufacturer in terms of the actual outside diameter and the actual wall

AcomAcomAcomAcom Expansion Joint ItalyExpansion Joint ItalyExpansion Joint ItalyExpansion Joint Italy
thickness of the pipe. The outside diameters, schedules, and wall thickness of pipe sizes up thru36 inches can be found in the American National Standards Institute Standards (ANSI BSG.1 0). A-3.2 FLOWING MEDIUM The substances that will come in contact with the expansion joint should be specified. In some cases, due to excessive erosion, or corrosion potential, or in cases of high viscosity, special materials and accessories should be specified. When piping systems containing expansion joints are cleaned periodically, the cleaning solution must be compatible with the bellows material. A-3.3 PRESSURE Pressure is possibly the most important factor determining expansion joint design. Minimum and maximum anticipated pressure should be accurately determined. If a pressure test is to be performed, this pressure should be specified as well. While the determination of pressure requirements is important, care should be exercised to insure that these specified pressures are not increased by unreasonable safety factors as this could result in a design which may not adequately satisfy other performance characteristics. A-3.4 TEMPERATURE The operating temperature of the expansion joint will affect its pressure capacity, allowable stresses, cycle life, and material requirements. All possible temperature sources should be investigated when determining minimum and maximum temperature requirements. In so doing, however, it is important that only those temperatures occurring at the expansion joint location itself be specified. Specifying temperatures remote from the expansion joint may unnecessarily result in the need for special materials at additional expense. A-3.5 MOTION Movements due to temperature changes or mechanical motion to which the expansion joint will be subjected must be specified. (Methods for determining movements are presented in Section 2.) In addition, other extraneous movements, such as wind loading or installation misalignment must be considered.

The various dimensional changes, which an expansion joint is required to absorb, such as those resulting from thermal changes in a piping system, are as follows (Fig. A-5): Axial Motion is motion occurring parallel to the centerline of the bellows and can be either extension or compression. Lateral Deflection, or offset, is motion which occurs perpendicular, or at right angles to the centreline of the bellows. Lateral deflection can occur along one or more axis simultaneously. Angular Rotation is the bending of an expansion joint along its centreline. A-4 EXPANSION JOINT ACCESSORIES
The basic unit of every expansion joint is the bellows. By adding additional components, expansion joints of increasing complexity and capability ate created which are suitable for a wide range of applications. Refer to Figure A-7 and the following list for a description of the basic expansion joint accessories

AcomAcomAcomAcom Expansion Joint ItalyExpansion Joint ItalyExpansion Joint ItalyExpansion Joint Italy
1. BELLOWS - The flexible element of an expansion joint, consisting of one or more convolutions, formed from thin material. 2. LINER - A device which minimises the effect on the inner surface of the bellows by the fluid flowing through it. Liners are primarily used in high velocity applications to prevent erosion of the inner surface of the bellows and to minimise the likelihood of flow induced vibration. Liners come in single, tapered, or telescoping configurations according to the application requirements. An expansion joint, if provided with liners, must be installed in the proper orientation with respect to flow direction. Liners are sometimes referred to as internal sleeves. 3. COVER- A device used to provide external protection to the bellows from foreign objects, mechanical damage, and/or external flow. The use of a cover is strongly recommended for all applications. A cover is sometimes referred to as a shroud. 4. WELD END-The ends of an expansion joint equipped with pipe for weld attachment to adjacent equipment or piping. Weld ends are commonly supplied bevelled for butt-welding. 5. FLANGED END the ends of an expansion joint equipped with flanges for the purpose of bolting the expansion joint to the mating flanges of adjacent equipment or piping. 6. COLLAR- A ring of suitable thickness which is used to reinforce the bellows tangent, or cuff, from bulging due to pressure. 7. HOLLOW REINFORCING RINGS- Devices used on some expansion joints, fitting snugly in the roots of the convolutions. The primary purpose of these devices is to reinforce the bellows against internal pressure. Hollow rings are usually formed from a suitable pipe or tubing section.

8. SOLID ROOT RINOS- Identical in function to hollow root rings but formed from solid bar stock for greater strength. 9. EQUALIZING RINGS- "T" Shaped' cross-section these rings are made of cast iron, steel stainless steel or other suitable alloys. In addition to resisting internal pressure, equalising rigs limit the amount of Compression movement per convolution. 10. CONTROL RODS Devices. Usually in the form of rods or bars, attached to the expansion join assembly whose primary function is to distribute the applied movement between the two bellows of a universal expansion joint. Control rods arc NOT designed to restrain bellows pressure thrust. 11. LIMIT RODS- Devices. Usually in the form of rods or bars, attached to the expansion joints whose primary function is to restrict the bellows movement range (axial, lateral, angular) during normal operation. In the event of a main anchor failure, limit rods are designed to prevent bellows over-extension or over-compression while restraining the full pressure loading and dynamic forces generated by the anchor failure 12. TIE RODS Devices usually in the form of rods or bars, attached to the expansion joint assembly whose primary function is to continuously restrain in the full bellows pressure thrust during normal operation while permitting lateral deflection. Angular rotation can be accommodated only In two the rods are used and located 90° from the direction of rotation. 13. PANTOGRAPHIC LINKAGE- A scissors-like device. A special form of control rod attached to the expansion joint assembly whose primary function is to positively distribute the movement equally between the two bellows of the universal joint throughout its full range of movements. Pantographic linkage are NOT, designed to restrict pressure thrust.

A-6 TYPES OF EXPANSION JOINTS
There are several different types of expansion joints. Each is designed to operate under a specific set of design conditions The following is a listing of the most basic types of expansion joint designs, along with a brief description or their features and application requirements. A more in-depth discussion of specific expansion joint application appears in Section B-2All of the following expansion joint types are available in both circular and rectangular models l) SINGLE EXPANSION JOINT The simple’s form of expansion joint; of a single bellow construction, it absorbs all of the movement of the pipe section into which it is installed. (Fig A4) 2) DOUBLE EXPANSION JOINT A double expansion joint consists of two bellows jointed by a common connector, which is anchored to some rigid part of the installation by means of en anchor base. The anchor base may be attached to the common connector either at installation or time of manufacturer. Each bellows or a double expansion function independently as a single unit. Double bellows expansion joint expansion should not be confused with universal expansion joints. (Fig A5) 3) UNIVERSAL TIED EXPANSION JOINT Tied Spherical Expansion Joints are used when it is necessary for the assembly to eliminate pressure thrust forces from the piping system. In this case the expansion joint will absorb lateral movement and will not absorb any axial movement external to the tied length

4) HINGED EXPANSION JOINT A Hinged Expansion Joints contains one bellows and is designed to permit angular rotation in one plane only by the use of a pair of pins running through plates attached to the Expansion Joints ends. Hinged Expansion Joints should be used in set of 2 or 3 function properly. 6) GIMBAL EXPANSION JOINT A Gimbal Expansion Joints is designed to permit angular rotation in any plane by the use of 2 pairs of hinges affixed to a common floating gimbal ring.
7) PRESSURE BALANCED EXP. JOINTS Pressure Balanced Expansion Joints is designed to absorb axial movement and / or lateral deflection while restraining the bellows pressure thrust force (Sect. 1.3.2) By means of the device inter connecting the flow bellows with an opposed bellows also subjected to line pressure. This type of Expansion Joints is installed where a change of direction occurs in a run of pipe.

B- 1 SYSTEM PREPARATION
When thermal growth of a piping system has been determined to be a- problem,
and the use of an Expansion Joint is indicated, the most effective Expansion Joint should be selected as a solution. When using Expansion Joint it should be kept in mind that movements are not eliminated, but are but are only directed to certain points where they can best be absorbed by Expansion Joint. The methods used and the steps that must be taken in preparing a piping system for the introduction of an Expansion Joint is covered in this section. As will been seen, many factors have to be considered to insure the proper functioning of Expansion Joint.
B- 1.1 SIMPLIFIES THE SYSTEM - The first step in the selection of Expansion
Joint is to choose the tentative location of the pipe anchors. The purpose of the anchors is to divide a piping system into simple individual expending section. Since thermal growth cannot be restrained, it becomes the function of the pipe anchors to limit and control the amount of movement that the Expansion Joint installed them must absorb. It is single or double expansion joints in straight axial movement generally advisable to begin with the assumption that using sit will provide the most simple and economical layout. Never install more than one "single" type joint between any two anchors in a straight run of pipe
In general piping systems should be anchored so that a complex system is
divided into several sections, which conform to one of the configurations shown in Fig. B-1
Standard Supports 99 14
AcomAcomAcomAcom Expansion Joint ItalyExpansion Joint ItalyExpansion Joint ItalyExpansion Joint Italy
Major pieces of equipment such as turbines, pump, and compressors. Etc. may function as anchor provided they are designed for this use. Fig. B-2 illustrates hypothetical piping system in which Expansion Joint is to be installed. The following sections describe Expansion Joint application methods as applied to this system.
B-1.2 CALCULATING THERMAL GROWTH - Step 1 in determining thermal movement is to choose tentative anchor position. The goal here is divide system into several straight-line sections exhibiting only axial movement. Referring to Fig. B-3 demonstrates this method. The pump and two tanks are logical anchor positions. The addition of anchors at points. B and C result in the desired series of straight-line piping legs. The next step is determine the ho actual change in length of each of the piping legs due to changes in temperate ambient temperature outside the system can contribute to thermal movement. Movements caused by other sources such as mechanical movements or wind loading must also be considered. B-1.3 PIPEANCHORS AND FORCES - Pipe anchors, their attachments, and the structures to which they are attached, must be designed to withstand all of the forces acting upon them. In addition to the normal pipe system forces, anchors in systems, which contain expansion joints, are subjected to additional forces. Two significant forces, which are unique to expansion joint systems, are spring forces and pressure thrust force. B-1.3.1 SPRING FORCE - spring force is the force required to deflect an expansion joint specific amount. It is based on operating conditions and materials. Spring force imparts a resisting force throughout the system much as a spring would when compressed or otherwise deflected. (Fig. B-4) in order for an expansion joint to operate properly, this spring force must be restrained by anchors.
Standard Supports 99 15
AcomAcomAcomAcom Expansion Joint ItalyExpansion Joint ItalyExpansion Joint ItalyExpansion Joint Italy
The magnitude of spring force is determined by the Expansion Joint spring's rate and by the amount of movement to which the Expansion Joint is subjected. The spring rate varies for each Expansion Joint and is based upon the physical dimensions and material of a specific Expansion Joint. A simple example will illustrate the magnitude of spring force for en Expansion Joint installed in a 24" diameter pipe system. The axial spring rate is given as: 1568 Lbs./in if the Expansion Joint deflects 1/2 in axially the spring force is
B-1.3.2 PRESSURE THRUST FORCE - Pressure thrust forces is often misunderstood. It is a condition created by the installation of a flexible unit- such as an Expansion Joint into a rigid piping system, which is under pressure. Pressure thrust force is a function of the system pressure and mean diameter (Fig. B-5) of the bellows. Mean diameter is determined by the height, or span, of he bellows end can vary from unit to unit. Mean diameter (DP) is usually greater then the pipe diameter.
Fig.B-5 illustrates the effect of pressure on a bellows convolution. In cases of internal or positive pressure, the convolutions ere pushed apart, causing the bellows to extend or increase in length while the opposite is observed in cases of external or negative pressure. The force required maintaining the bellows at its proper length is equal to this pressure thrust and can be significantly higher all other system forces combined. See Fig. (B-6) for further details of pressure thrust effects.
Spring Force =1568*0.5 = 784 lbs.
Standard Supports 99 16
AcomAcomAcomAcom Expansion Joint ItalyExpansion Joint ItalyExpansion Joint ItalyExpansion Joint Italy
B- 1.3.3 DETERMING PRESSURE THRUST FORCE The magnitude of pressure thrust force is determined by the following equation.
Where: (P) is the pressure And: (a) is the effective area of the Expansion Joint The following example will illustrate the effect of pressure thrust. Suppose that an expansion joint is to be installed in a 24-in. diameter pipe system, which operates a 1 50-pig pressure. From the manufacturer of the expansion joint the effective area is found to be 560 in2. The pressure thrust force (Fs) is found to be: Fs = P a or Fs = (1 50) (560) = 84,000 lbs. that when determining pressure thrust forces, the pressure value used in Fs = P a should equal the maximum anticipated pressure that the system is likely to experience. For this reason, any pressure test must be considered. Be careful not to specify unrealistic safety factors which could lead to over-desi9n of the anchors at additional cost. The force is transmitted from the ends of the expansion joint along the pipe. Referring to Fig. B6, a comparison of the effect of pressure thrust is shown between a section of rigid pipe (A) and a flexible bellows (B). In an unpressurized state, there is no pressure thrust force transmit by A or B and their length same Under internal force is acting upon both A and B that is equal sure times the E of A & B. The force of this thrust is totally absorbed by the rigid walls and its length remain unchanged. The length of B will tend to increase under internal pressure since the flexible expansion joint is unable to resist the force. It therefore yields. or stretches..In cases of external pressure or vacuum conditions, the effects of internal pressure is reserved and the Expansion Joint will tend to compress. To stop the expansion joint from extending or compressing due to pressure thrust, main anchors must be located at some point on each side of the joint to withstand the forces of may also be used to restrain pressure thrust force by attaching the ends of the expansion joint to each other. In this case, these restraints prevent the bellows from absorbing any axial movement external to
Fs = P a
Standard Supports 99 17
AcomAcomAcomAcom Expansion Joint ItalyExpansion Joint ItalyExpansion Joint ItalyExpansion Joint Italy
the expansion joint. Pressure-balanced expansion joints restrain pressure thrust and absorb axial movement external to the joint. As can be seen, the forces exerted on a piping system due to the presence of expansion joints can be quite significant. In the preceeding example the spring force was found to be 784 lbs., while the pressure thrust force was equal to 84,000 lbs.- a combined force of 84,784 lbs.! One can see that proper anchoring of a piping system containing expansion joints is vital. B-1 .3.4 MAIN ANCHORS - 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 one or more unrestrained expansion joints, these will consist of the full bellows thrust due to pressure, media flow, the forces and/or moments required to deflect the expansion joint or joints their full rated movement, and the frictional forces caused by the pipe guides, directional anchors and supports. In certain applications it may be necessary to consider the weight of the pipe and its contents and any other forces and/or moments resulting from wind loading etc.
In systems containing expansion joints, main
anchors are installed at any of the following locations:
A) At a change of direction of flow: B) Between two expansion joints of different
sizes installed in the same straight run: C) At the entrance of a side branch containing
an expansion joint into the main line: D) Where a shut-off or pressure mg valve is
installed in a pipe run between two expansion joints
E) At a blind end of pipe B-1.3.5 INTERMEDIATE ANCHORS-Intermediate anchors are not intended to withstand press are thrust force. This force is absorbed by main anchors, by devices on the expansion joint such as tie rods, swing bars, hinges, gimbals, etc., or, as in the case of a pressure balanced or double expansion joint, is balanced by an equal pressure force acting in the opposite direction. An intermediate anchor must withstand all of the non-pressure forces acting upon it by each of the
Standard Supports 99 18
AcomAcomAcomAcom Expansion Joint ItalyExpansion Joint ItalyExpansion Joint ItalyExpansion Joint Italy
pipe sections to which it is attached. In the case of a pipe section containing an expansion joint, these forces will consist of the force required to move the expansion joint and the frictional forces caused by the pipe guides.
B-1.4 PIPE GUIDES AND SUPPORTS - Correct alignment of the pipe adjoining an expansion joint is of vital importance to its proper function. Although expansion joints are designed and built for a long and satisfactory life, maximum service will be obtained only when the pipeline has the recommended number of guides and is anchored and supported in accordance with good piping practice. Proper supporting of the pipeline is required not only to sup-port the pipe itself, but also to provide support at each end of the expansion joint. Pipe guides are necessary to insure proper alignment of movement to the expansion joint and to prevent buckling of the line. Buckling is caused by a combination of the expansion joint flexibility and the internal pressure loading on the pipe which causes it to act like a column loaded by the pressure thrust of the expansion joint. (Fig. B-8.1)
Fig B.8
Standard Supports 99 19
AcomAcomAcomAcom Expansion Joint ItalyExpansion Joint ItalyExpansion Joint ItalyExpansion Joint Italy
B-1.4.1PIPE GUIDE APPLICATION - When locating pipe guides fapplications involving axial movement only, it is generally recommended that the expansion joint be located near an anchor, and that the first guide be located a maximum of 4 pipe diameters away from the expansion joint. This arrangement will provide proper movement guiding as well as proper support for each end of the expansion joint. The distance between the first and second guide should not exceed 1 4 pipe diameters, and the distance between the remaining anchors should be determined from paragraph B-2.2.2. of the Acom Practical Guide. Common types of pipe guides are shown in Fig. B-9. For systems subjected to lateral motion or angular rotation, directional anchors or planar guides may be required. Examples of these guides are shown in Section B-2. The recommendations given for pipe anchors and guides represent the minimum requirements for controlling pipelines which contain expansion joints and are intended to protect the expansion joint and pipe system from abuse and failure. However, additional pipe supports are often required between guides in accordance with standard piping practice. B-1.4.2 PIPE SUPPORT APPLICATIONS A pipe support is any device which permits free movement of the piping while carrying the dead weight of the pipe and any valves or attachments. Pipe supports must also be capable of carrying the live weight. Pipe supports cannot be substituted for pipe alignment or planar guides. Pipe rings, U-bolts, roller supports, spring hangers etc., are examples of conventional pipe support devices

B-2 EXPANSION JOINT APPLICATIONS The following examples demonstrate common types of expansion joint applications,
some dealing with simple axial movement and others with more complex and specialized applications.
B2.1 AXIAL MOVEMENT Figure B-10 typifies good practice in the use ofa single expansion joint to absorb axial pipeline expansion. Note the use of just one expansion joint between anchors, the nearness of the joint to an anchor and the spacing of the pipe guides
Fig. B-11 typifies good practice in the use of a double expansion joint to absorb axial pipeline expansion. Note the addition of the intermediate anchor which, in conjunction with the two main anchors effectively divides this section into two distinct expanding segments, so that there is only one expansion joint between anchors.

Fug B.12
Figure B.12 typifies good practice in the use of Acom Expansion Joints to absorb axial expansion in a pipeline with a branch connection. The anchor at the junction, which is in this case a tee, is a main anchor designed to absorb the thrust force from Expansion Joint in the branch line. Note the nearless of each Expansion Joint to an anchor , the closness of each first alignment guide.
Fi. B13
Fig. B-13 typifies good practice in the use of a pressure balanced expansion joint (Section A-6, Paragraph 8) to absorb axial movement. Note that the expansion joint is located at a change of direction of the piping and that the elbow and the end of the pipe are secured by intermediate anchors. Since the pressure thrust is absorbed by the expansion joint itself, and only the force required to deflect the expansion joint is imposed on the piping, a minimum of guiding is required. Guiding near the expansion joint as shown will frequently suffice. In long, small-diameter pipelines, additional guiding may be necessary.

B-2.2 COMBINED MOVEMENTS, LATERAL DEFLECTION, AND ANGULAR ROTATION - Because it offers the lowest expansion joint cost, the single expansion joint is usually considered first for any application. Fig. B-14 shows a typical application of a single expansion joint used to absorb lateral deflection, as well as axial compression. The joint is located near the end of the long pipe run with main anchors at each end and guides properly spaced for both movement control and protection of the piping against buckling. In this case, as opposed to the similar configuration in Fig. B-1 Other anchor at left is a directional main anchor which, while absorbing the main anchor loading in the direction of the expansion joint axis, permits the thermal expansion of the short leg to act upon the expansion joint as lateral deflection. Because the main anchor loading (pressure thrust) exists only in the leg containing the expansion joint, the anchor at the end of the short piping leg is an intermediate anchor.
Fig.B14

Figure B-15 represents modifications of Figure B-1 0 in which the main anchors at either end of the expansion joint are replaced by tie rods. Where the piping configuration permits, the use of the tie rods adjusted to prevent axial movement frequently simplifies and reduces the cost of the installation. Because of these tie rods, the expansion joint is not capable of absorbing any axial movement other than its own thermal expansion (See Section B-i .3.3). The thermal expansion in the short leg is imposed as deflection on the long piping leg. Fig. B-1 6 shows a tied universal expansion joint used to absorb lateral deflection in
a single plane Z bend. The thermal movement of the horizontal lines is absorbed as lateral deflection by the expansion joint. Both anchors need only to be intermediate anchors since the pressure thrust is restrained by the tie rods. Where p055ible, the expansion joint should fill the entire offset leg so that its expansion is absorbed within the tie rods as axial movement, and bending in the horizontal lines is minimized.

Figure B-17 shows a typical application of a tied universal expansion joint in a 3-plane Z' bend. Since the universal expansion joint can absorb lateral deflection in any direction, the two horizontal legs may lie at any angle in the horizontal plane. Figure B-1 8 shows a case of pure angular rotation using a pair of hinge joints in a single-plane 'Z' bend. Since the pressure thrust is restrained by the hinges, only
intermediate anchors are required. The axial expansion of the pipe leg between the expansion joints is imposed on the two horizontal legs if there is sufficient flexibility.If not, a 3 hinge system such as in Fig. B-19 may be required. The thermal expansion of the offset leg is absorbed by joints A,B,C. Expansion joint (B) must be capable of absorbing the total of the rotation of (A) & (C)

Hence, it is frequently necessary that the center expansion joint contain a greater number of convolutions than those at either end. Just as hinged expansion joints may offer great advantages in single-plane applications, gimbal expansion joints are designed to offer similar advantages in multi-plane systems. The ability of gimbal expansion joints to absorb angular rotation in any plane is frequently applied by utilizing two such units to absorb lateral deflection.
Figure B-20 shows a case of pure angular rotation using a pair of gimbal expansion joints in a multi-plane 'Z' bend. Since the pressure thrust is restrained by the gimbal

assemblies, only intermediate anchors are required
In applications where the flexibility of the two horizontal piping legs is not sufficient to absorb the axial growth of the pipe section between the two gimbal joints in Figure B-20, the addition of a hinge joint, as shown in Figure B-21, is indicated. Since the expansion of the offset leg takes place in only one plane, the use of the simpler hinge expansion joint is justified.

C-1 INSTALLATION Metal bellows-type expansion joints have been designed to absorb a specified amount of movement by flexing of the thin-gage bellows. If proper care is not exercised in the installation of the expansion joint, cycle life and pressure capacity could be reduced, leading to premature failure and damage to the piping system. It is important that the expansion joint be installed at the length specified by the manufacturer. They should never be extended or compressed in order to make up for deficiencies in length, nor should they be of set to accommodate misaligned pipe. Remember that a bellows is designed to absorb motion by flexing. The bellows, therefore, must be sufficiently thick to withstand the design pressure, while being thin enough to absorb the required flexing. Optimum design will always require a bellows to be of thinner material than virtually any other component in the piping system in which it is installed. The installer must recognize this relative fragility of the bellows and take every possible measure to protect it during installation. Avoid denting, weld spatter, arc strikes or the possibility of allowing foreign matter to interfere with the proper flex mg of the bellows. It is highly recommended that a cover be specified for every expansion joint The small cost of a cover is easily justified when compared to the cost of replacing a damaged bellows element, With reasonable care during storage, handling, and installation, the user will be assured of the reliability designed and built into the expansion joint. C-3 DO'S AND DON'TS - INSTALLATION AND HANDLING The following recommendations are included to avoid the most common errors that occur during installation. When in doubt about an installation procedure, contact the manufacturer for clarification before attempting to install the expansion joint.

DO'S. Do ... Inspect for damage during shipment such as: dents, broken hardware, water marks on carton, etc. Do ...Store in a clean, dry area where it will not be exposed to heavy traffic or damaging environment. Do... Use only designated lifting lugs when provided. Do... Make the piping system fit the expansion joint. By stretching, compressing, or offsetting the joint to fit the piping, the expansion joint may be over stressed when the system is in service. Do... Leave one flange loose on the adjacent piping when p055ible, until the expansion joint has been fitted into position. Make necessary adjustments of this loose flange before welding. Do .. Install the joint with the arrow pointing in the direction of flow. Do... Install single vanstone liners pointing in the direction of flow. Be sure also to install a gasket between a vanstone liner and flange. Do... In case of telescoping liner, install the smallest I.D. liner pointing in the direction of flow. Do... Remove all shipping devices after the installation is complete and before any pressure test of the fully installed system. Do... Remove any foreign material that may have become lodged between the convolutions. Do... Refer to the proper guide spacing and anchoring recommendations in Section B-1 .3 & B-1 .4.

AcomAcomAcomAcom Expansion Joint ItalyExpansion Joint ItalyExpansion Joint ItalyExpansion Joint Italy
DON'T'S... Don't....Drop or strike expansion joint. Don't....Remove the shipping bars until the installation is complete Don't....Remove any moisture-absorbing desiccant bags or protective coatings until ready for installation. Don't....Use hanger lugs or shipping bars as lifting lugs. Don't... Use chains or any lifting device directly on the bellows or bellows cover. Don't....Allow weld spatter to hit unprotected bellows. Don't....Use cleaning agents which contain chlorides. Don't....Use steel wool or wire brushes on bellows. Don't....Force or rotate one end of an expansion joint for alignment of bolt holes. Bellows are not ordinarily capable of absorbing torsion. Don't....Hydrostatic pressure test or evacuate the system before proper installation of all guides and anchors. Don't....Use shipping bars to restrain the pressure thrust during testing. Don't....Use pipe hangers as guides. Don't....Exceed the manufacturers rated test pressure of the expansion joint CAUTION: The manufacturers warranty may be void if improper installation procedures have been used.

C 3 SAFETY RECOMMENDATION This section was prepared in order to better inform the user of hose -factors which many years of experience have shown to be essential for the successful installation and performance of piping systems containing bellows expansion joints. C-3.1 INSPECTION PRIOR TO START-UP OR PRESSURE TEST -Expansion joints are usually considered to be non-repairable items and generally do not fall into the category for which maintenance procedures are required. However, immediately after the installation is complete a careful visual inspection should be made of the entire piping system to insure that there is no evidence of damage, with particular emphasis on the following: 1. Are anchors, guides, and supports installed in accordance with the system drawings? 2. Is the proper expansion joint in the proper location? 3. Are the expansion joint's flow direction and pre positioning correct? 4. Have all of the expansion joint shipping devices been removed? 5. If the system has been designed for a gas, and is to be tested with water, has provision been made for proper support of the additional dead weight load on the piping and expansion joint? Some water may remain in the bellows convolutions after the test. If this is detrimental to the bellows or system operation, means should be provided to remove this water.? 6. Are all guides, pipe supports and the expansion joints free to permit pipe movement 7. Has any expansion joint been damaged during handling and installation? 8. Is any expansion joint misaligned ? This can be determined by measuring the joint overall length, inspection of the convolution geometry, and checking clearances at critical points on the expansion joint and at other points in the system. 9. Are the bellows and other movable portions of the expansion joint free of foreign material? C-3.2 INSPECTION DURING AND IMMEDIATELY AFTER PRESSURE TEST- WARNING: Extreme care must be exercised while inspecting any pressurized system or component. A visual inspection of the system should include the following: 1 Evidence of leakage or loss of pressure 2 Distortion or yielding of anchors, expansion joint hardware, the bellows and
other piping components 3 Any unanticipated movement of the piping due to pressure 4 Evidence of instability in the bellows 5 The guides, expansion joints, and other movable parts of the system should
be inspected for evidence of binding. 6 Any evidence of abnormality or damage should be reviewed and evaluated by competent design authority.

C-3.3 PERIODIC INSERVICE INSPECTION - WARNING: Extreme care must be exercised while inspecting anypressurized system or component. 1. Immediately after placing the system in operation, a visual inspection should beconducted to insure that the thermal expansion is being absorbed by the expansion joints in the manner for which they were designed. 2. The bellows should be inspected for evidence of unanticipated vibration. 3. A program of periodic inspection should be planned and conducted throughout the operating life of the system. The frequency of these inspections should be determined by the service and environmental conditions involved. Such inspections can spot the more obvious potential problems such as external corrosion, loosening of threaded fasteners, and deterioration of anchors, guides and other hardware.IT MUST BE UNDERSTOOD THAT THIS INSPECTION PROGRAM, WITHOUT ANY OTHER BACKUP INFORMATION,CANNOT GIVE EVIDENCE OF DAMAGE DUE TO FATIGUE,STRESS CORROSION OR GENERAL INTERNAL CORROSION. THESE CAN BE THE CAUSE OF SUDDEN FAILUREAND GENERALLY OCCUR WITHOUT ANY VISIBLE OR 4.When any inspection reveals evidence of malfunction, damage, or deterioration, this should be reviewed by competent design authority for resolution. Additionally, any changes in the system operating conditions such as pressure, temperature, movement, flow, velocity, etc. that may adversely affect the expansion joint should be reported to and evaluated by a competent design authority. 1. C- 4 SPECIFICATION AND ORDERING GUIDE This guide has emphasized that the most reliable and safe bellows expansion joint installations are the result of a high degree of understanding between the user and the manufacturer. The prospect for successful long-life performance of piping systems containing expansion joints begins with the submittal of accurate data by the system designer. When preparing specifications for expansion joints, it is imperative that the system designer completely review the piping system layout and provide the necessary data relating to the selection of an expansion joint: flow medium, pressure, temperature, movements, etc. To aid the user in the specification and ordering of expansion joints, the Expansion Joint Manufacturers Association has provided the following standard expansion joint specification sheets. Complete data, when submitted in accordance with these specifications, will help in obtaining an optimum design. Other data that must be considered but which is not covered, may be included in the "remarks" section of the specification sheets.
