Expansion joint is also called pipe expansion joint, expansion joint, compensator and expansion joint. The expansion joint is a new product for the connection of pumps, valves, pipelines and other equipment with pipelines. It is connected by full bolts to make it a whole, and has a certain displacement, which is convenient for installation. It can bear the axial pressure of pipeline. In this way, the installation and maintenance can be adjusted according to the on-site installation size. When working, it not only improves the work efficiency, but also plays a certain role in protecting the pumps, valves and other pipeline equipment.
The connection form of the expansion joint is flange connection, with one side flange and one side welding.
1. Compensate the expansion deformation caused by axial, transverse and angular heating of absorption pipeline.
2. Absorb equipment vibration and reduce the influence of equipment vibration on pipeline.
3. Absorb the deformation of pipeline caused by earthquake and ground subsidence.
Because of the heat expansion and cold contraction of the pipeline, the stress and push-pull force of the pipe wall will be produced for the pipeline; The stress of the pipe wall affects the strength of the pipe. With the increase of the push-pull force, the fixed support of the pipe has to do a lot to bear the push-pull force caused by the expansion of the pipe; In order to reduce the stress and thrust of the pipe wall, the expansion joint compensation is used.
