Spherical compensator compensator is also called expansion joint, bellows compensator. Compensators are divided into several types: ripple compensator, sleeve compensator, rotary compensator, square natural compensator and so on. Among them, ripple compensator is commonly used, mainly to ensure the safe operation of pipelines, which has the following functions:

1. Compensation for thermal deformation of absorption pipeline in axial, transverse and angular directions.

2. The expansion of the corrugated compensator facilitates the installation and disassembly of the valve pipeline.

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

4. Absorbing the deformation of
