Axial Expansion Joints
As an axial expansion joint is the least expensive type of individual unitavailable it is often selected for use in a piping system without regard for thepossible problems involved and the costof the installation.
AnchorsIn order for an axial expansion joint to function, the pipeline must be properly guided and must have anchorsstrong enough to overcome the pressurethrust. This pressure thrust can becalculated as follows:
Effective Area x Internal Pressure
The pressure thrust for any unrestrainedbellows is given in the reference tables.The pressure thrust at test pressure is 1.5 times the value shown.
Pipe guidesAssuming that we have a structureavailable on which to anchor the pipework, it is essential to accurately guidethe pipe to ensure alignment, otherwisethe tendency of the expansion jointwould be to distort sideways resulting in early failure.
Pipe guides should be installed in the locations shown here in Fig 1 and Fig 2. For intermediate pipe guidespacing see Fig 3.
Pipe guides should be designed to permit the necessary axial travel with the least friction possible.
See Appendix 1 for Guide spacing diagram.
Intermediate anchorsIntermediate anchors must be designedto withstand spring forces but not thepressure thrust forces (See Fig 3).
Tied, hinged or gimbal bellows onlyrequire intermediate anchors to absorbthe resultant spring force due to thebellows movement. In these joints thehardware restrains the pressure thrustfrom being transmitted onto theintermediate anchors.

Application details for Double Tied Expansion Joint
The double tied expansion joint is wellsuited to allow lateral deflection in thelow to medium pressure range.
Used in this manner the tie rods willabsorb the pressure thrust. The designmay also be used to absorb axialmovement but this would result in thepressure thrust being taken from the tierods and transmitted to the anchors oradjacent equipment.
Fig 4 shows a double tied expansion jointused to absorb lateral deflection in asingle plane. Wherever feasible theexpansion joint should be designed to fillthe entire leg so that the expansion ofthis leg is absorbed within the tie rods asaxial movement.
Fig 5 shows a double tied expansion jointused to absorb lateral deflection in athree–plane configuration. As theexpansion joint will absorb lateraldeflection in any direction, the twohorizontal piping legs may lay at anyangle in the horizontal plane.
To ensure that this style of joint iscorrectly installed without any thrustbeing transmitted to adjacentequipment, it may be necessary to utilizeeither double hinged or double gimbalexpansion joints.

Wherever possible we recommend theuse of hinged type expansion joints toabsorb movement. This is because:
> All pressure thrust is held by the hingepins and is not imposed on pipework,anchors or equipment.
> Force to deflect the bellows is minimal
> On short pipe runs e.g. boiler housesystems, guides are not required. Onlong runs only simple pipe guides arerequired
> One pair of hinged joints can absorbvery large amounts of expansion,offering considerable savings inguides, anchors and actual joint cost
A hinged joint is designed to angulate.To compensate for most pipe movementsa set of three hinged units is necessary.Some typical layouts are shown in figure6 to 15.
We often supply two joints formed into aDouble hinged expansion joint. This savesthe cost of four flanges and makesinstallation simpler.

External Pressurised Expansion Joints
The XT Externally Pressurized ExpansionJoint is designed so that the pressure isexternal to the bellows whilst the insideis at atmospheric pressure. With thisdesign, when a pipeline expands, theexpansion joint compresses, but in doingso it stretches the bellows. The result ofthis is that many convolutions acttogether to allow a large amount of axialmovement because under externalpressure the bellows is completely stableas in Fig. 22.
The XT style of the joint is relativelyinexpensive and is designed primarily tofit the following applications:
a) In tunnels or locations wherearticulated joints can not be used but where large amounts of axialexpansion have to be absorbed. Itwould normally be less expensive toinstall one XT joint than to divide thepipeline up into several sets ofexpansion joint, anchors and guides. It is impractical to use more than twonormal bellows together because ofthe tendency of the bellows to squirmonce a certain length–diameter ratio is exceeded.
b)At extremely high pressure even short bellows can become unstableunder internal pressure. This can beovercome but the use of an XT typejoint, which has the bellows undertension and therefore stabilized.
c) Where it is undesirable to have solidsaccumulate in the convolutions of anexpansion joint. The XT can be fittedwith drains or manholes to facilitatethe regular cleaning out of these areas.

With this type of joint, the pressure isbalanced by allowing the pressure topass through a hole in the back of thebend into a sealed bellows having thesame effective area. Tie rods are used tobalance the bellows so that as the linebellows is compressed due to thermalexpansion, the other bellow is extended.
For large amounts of lateral movement,we would prefer the use of a DoublePressure Balanced Joint as shown in Figs24 to 28.
Some typical piping layouts using PBEJare shown in Figs 25 to 27.
In exceptional circumstances where aPBEJ cannot be incorporated into achange of pipe direction, then an in–lineaxial Pressure Balanced Expansion Jointcan be supplied.
Jord Bellows can supply a wide range of rubber expansion joints to suit manydifferent applications. Rubber expansionjoints are often used in water andchemical applications where lateralmovement, misalignment or vibration are evident in the piping system.
