Axial internal pressure corrugated expansion joint , Bellows expansion joints,
Axial internal pressure corrugated expansion joint, metal corrugated expansion joint.
Connection: welding, flange connection
It is mainly to ensure the safe operation of the pipeline and has the following functions:
1. Absorb axial, transverse and angular thermal deformation of pipes.
2. The expansion and contraction of the corrugated expansion joint is convenient for the
installation and disassembly of the valve pipeline.
3. Absorb equipment vibration and reduce the impact of equipment vibration on the pipeline.
4. Absorb the deformation of vibration and subsidence on the pipeline.
The expansion joint is composed of a bellows and a structure, which is mainly used to absorb axial
displacement and a small amount of lateral and angular displacement, and the structure is simple and the cost is low.
