Corrugated compensator, also called expansion joint and expansion joint, consists of bellows (an elastic element) and end pipes, brackets, flanges, conduits and other accessories. It is a compensation device that uses the effective expansion and deformation of elastic elements of bellows compensator to absorb the dimensional changes of pipes, conduits or containers caused by thermal expansion and cold contraction, and belongs to compensation elements. It can absorb axial, transverse and angular displacement, and is used for heating displacement and mechanical displacement of pipelines, equipment and systems to absorb vibration and reduce noise. It is widely used in modern industry.

1. Compensate the axial, transverse and angular thermal deformation of the absorption pipeline.

2. The expansion and contraction of the corrugated compensator is convenient for the installation and disassembly of the valve pipeline.

3. Absorb equipment vibration and reduce the influence of equipment vibration on the pipeline.

4. Absorb pipeline deformation caused by earthquake and settlement.

The square natural compensator has two functions:

1. When the pipeline crosses the foundation beam or basement wall, it is necessary to install a square compensator to avoid the pressure of foundation settlement on the pipeline.

2. When the thermal pipeline is too long, it is necessary to install a square compensator to reduce the stretching of the pipeline caused by' thermal expansion and cold contraction'.
