Metal stainless steel bellow compensator flexible expansion joint for industrial pipeline
Flexible expansion joint compensator can be used to eliminate the pipelines, containers or equipment caused by climate change or other reasons caused by thermal expansion or displacement.Flexible expansion joint compensator can be installed on both ends of import and export or other high frequency mechanical pump to reduce or eliminate the vibration, improve the service life of the pipe and sealing performance. Butt welded flexible expansion joint compensator can also be used to absorb deviation of actual installation.it has reliable operation, compact structure, compensation ability is strong, resisting all kinds of medium corrosion and having long service life, etc.
Performance of flexible expansion joint
The main elastic element of flexible expansion joint is stainless steel bellows. Through the expansion and bending of bellows, the flexible expansion joint compensates the pipeline in axial, transverse and angular directions. Flexible expansion joint can play the following roles:
1. The flexible expansion joint absorbs the axial, transverse and angular thermal deformation of the pipeline.
2. Flexible expansion joint can absorb equipment vibration and reduce the influence of equipment vibration on pipeline.
3. Flexible expansion joint can absorb the pipeline deformation caused by earthquake and land subsidence.
