A Bellow Expansion Joint or movement joint is an assembly designed to safely absorb the heat-induced expansion and contraction of construction materials, to absorb vibration, to hold parts together, or to allow movement due to ground settlement or earthquakes. They are commonly found between sections of buildings, bridges, sidewalks, railway tracks, piping systems, ships, and other structures.
Building faces, concrete slabs, and pipelines expand and contract due to warming and cooling from seasonal variation, or due to other heat sources. Before expansion joint gaps were built into these structures, they would crack under the stress induced.
WHAT IS THE DIFFERENCE BETWEEN A BELLOWS AND AN EXPANSION JOINT?
The terminology can be confusing and often words have no universally accepted meaning. We use the following definitions but the terms “bellows” and “expansion joint” are typically considered as interchangeable:
Expansion Joint - an expansion joint is a complete unit with metal bellows or rubber bellows and end fittings, plus, optionally, liner, cover and external hardware. Other terms used - compensator, flexible connector.
Rubber Bellows - the flexible element within a rubber expansion joint
Metal Bellows - the flexible element within a metal expansion joint
Liner - The liner fits within the expansion joint under the metal bellows or rubber bellows to prevent the flowing media directly impinging on the bellows, this reduces flow disturbance and allows the temperature of the bellows to be controlled in the design.
Application
1) Central air-conditioning
2) Diesel engine (ship) exhaust line
3) Long distance pipeline such as Gas, steam, water etc.
4) Thermal expansion in Steel mill
5) Pipelines
6) Turbines
7) Compressors
8) Blowers
9) Vacuum pumps
10) Heat exchangers
11) Hot water and fire protection system
12) Compressors inlet and outlet

Advantages of Flanged Bellow Expansion Joint
1) Easy to absorb the expansion movements
2) No direction changes of the flow
3) Minimum application area
4) Possible lateral and angular expansion absorption by the additional bellows.
5) To provide a non-stressed area where the pressure is not too high such as pump and compressor applications.
6) Low application costs
