Flexible Steam Pipe Fittings Metal Multi-Ply Type Pipe Expansion Joint
Pipe 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.Pipe 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 pipe 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 pipe expansion joint
The main elastic element of pipe expansion joint is stainless steel bellows. Through the expansion and bending of bellows, the metal pipe expansion joint compensates the pipeline in axial, transverse and angular directions. Metal bellows can play the following roles:
1. The pipe expansion joint absorbs the axial, transverse and angular thermal deformation of the pipeline.
2. Pipe expansion joint can absorb equipment vibration and reduce the influence of equipment vibration on pipeline.
3. Pipe expansion joint can absorb the pipeline deformation caused by earthquake and land subsidence.
