Also called expansion joint or expansion joint. It consists of corrugated pipe (elastic element) and end pipe, bracket, flange, conduit and other accessories. Belonging to a compensation element. Using the effective expansion and contraction deformation of bellows as its working body, it can absorb the dimensional changes of pipes, conduits and containers caused by thermal expansion and contraction, or compensate the axial, lateral and angular displacement of pipes, conduits and containers. It can also be used to reduce noise and vibration. It is widely used in modern industry. In heating, in order to prevent the heating pipeline from being deformed or damaged due to thermal elongation or temperature stress, it is necessary to set a compensator on the pipeline to compensate the thermal elongation of the pipeline, so as to reduce the stress on the pipe wall and the force acting on the valve member or bracket structure.
Its functions are as follows:
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.
