Exhaust Compensator Stainless Steel 316l Flexible Metal Steam Bellow Expansion Joint
Bellow expansion joint is a compensation element, effective use of bellows telescopic body deformation, dimensional change in absorption pipeline, pipe, thermal expansion and contraction caused by pipeline transverse and angular displacement. It is mainly used for noise reduction and vibration reduction. It is widely used in modern industry.
Function of bellow expansion joint
1. compensating the axial, transverse and angular thermal deformations of the absorption duct.
2. to facilitate the installation and disassembly of valves and pipes.
3. to reduce the impact of equipment vibration on the pipeline.
