Expansion joints

Expansion joints are designed to safely absorb the movement in pipework systems due to heat-induced expansion and contraction of pipework.

Without them, pipes would not be able to withstand the forces exerted upon them and entire pipework systems would fail. When correctly selected and installed expansion joints act to prolong the service life of the pipework system and reduce the risk of downtime and for additional maintenance and repair.

How do they work?

Expansion joints - sometimes called expansion bellows, flexible joints or Expansion joint - are devices that comprise of a flexible element known as the bellows membrane that is fitted to end connections that are best suited to the pipework they are to be installed in.

What industries use expansion joints?

Expansion joints are used in all kinds of different sectors and in a huge range of different industrial contexts. Essentially, wherever there is a need to control pipework movement expansion joints are required.

What different varieties of expansion joints are there?

Expansion joint failure modes

Expansion joint failure can occur for various reasons, but experience shows that failures falls into several distinct categories.





Reliable research on Expansion joint

Compensator reliability is by the design, manufacture, installation and operation and management and other aspects of the composition. Reliability should also be considered from these aspects.

Pipe Expansion Joints

Pipe expansion joints are also known as compensators, as they 'compensate' for the thermal movement.

Ducted Air Systems

Expansion joints are required in large ducted air systems to allow fixed pieces of piping to be largely free of stress as thermal expansion occurs.



Metallic Pipe Expansion Joints

Metal pipe expansion joints can withstand the design temperatures, pressures, as well as, provide the capacity necessary to absorb thermal growth of the piping system.

The thermal movement required can be axial, lateral or angular. In some cases, the pressure thrust of a pipe expansion joint must be restrained by the use of tie rods, hinges or gimbal while allowing the bellows to move through its design deflections.

Expansion joints with stainless steel bellows

Sunny Steel offers a wide range of expansion joints, suitable for numerous specific applications.

What Are Expansion Joints?

Expansion joints are devices containing a bellows membrane that are designed to absorb dimensional changes, such as those that occur due to thermal expansion or contraction of a pipeline, duct or vessel.
