Ripple compensator stainless steel flexible joint pipe
Flexible joint pipe, also known as expansion joint, flexible joint pipe is composed of metal bellows and components, mainly to ensure the safe operation of the pipeline. Flexible joint pipe is a flexible thin-walled transverse bellows device with expansion function,. The principle of flexible joint pipe is to use its elastic expansion function to compensate the axial displacement, angular displacement, lateral displacement and combined displacement caused by thermal deformation, mechanical deformation and various mechanical vibration. Flexible joint pipes have the functions of pressure resistance, sealing, corrosion resistance, temperature resistance, impact resistance, vibration and noise reduction. The flexible joint pipe can reduce the deformation of the pipeline and improve the service life of the pipeline.
Performance of flexible joint pipe
The main elastic element of flexible joint pipe is stainless steel bellows. Through the expansion and bending of bellows, the joint expansions the pipeline in axial, transverse and angular directions. Metal bellows can play the following roles:
1. The flexible joint pipe absorbs the axial, transverse and angular thermal deformation of the pipeline.
2. Flexible joint pipe can absorb equipment vibration and reduce the influence of equipment vibration on pipeline.
3. Flexible joint pipe can absorb the pipeline deformation caused by earthquake and land subsidence.
