Universal Flexible Bellow Manufacturer Stainless Steel Metal Bellows Joint Expansion
Joint expansion is a kind of compensation element. The joint expansion effectively uses the deformation of bellows expansion body to absorb the lateral and angular displacement of pipeline caused by the change of pipeline size, thermal expansion and contraction of pipeline. Joint expansions are mainly used for noise reduction and vibration reduction. Joint expansions are widely used in modern industry.
Performance of joint expansion
The main elastic element of joint expansion 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 joint expansion absorbs the axial, transverse and angular thermal deformation of the pipeline.
2. Joint expansion can absorb equipment vibration and reduce the influence of equipment vibration on pipeline.
3. Joint expansion can absorb the pipeline deformation caused by earthquake and land subsidence.
