Description
Axial expansion joints aim to absorb the axial expansions.
- They do not change the direction of the flow
- Additional assemblage distance is not necessary
- Dividing the pipeline helps to prevent stress of lateral forces
Movement Absorption
Axial shift and slight all-around movement of the expansion joint is possible. Axial expansion joints with two bellows are used to absorb larger movements.
Advantages of Axial Expansion Joints
- Easy to absorb the expansion movements
- No direction changes of the flow
- Minimum application area
- Possible lateral and angular expansion absorption by the additional bellows.
- To provide a non-stressed area where the pressure is not too high such as pump and compressor applications.
- Low application costs
