bellows type expansion joint
The corrugated compensator belongs to a compensation element. The effective expansion deformation of the bellows of its working body is used to absorb the dimensional changes of pipelines, conduits and containers caused by thermal expansion and cold contraction, or to compensate the axial, transverse and angular displacement of pipelines, conduits and containers. It can also be used for noise reduction and vibration reduction. It is widely used in modern industry.
Performance of metal bellows
1. Good compensation effect
2. High temperature resistance
3. Metal dust boot can reduce leakage
4. Vibration resistance and high-speed performance
5. The specific pressure of the spring can be reduced
6. Possible torque transmission
7. Through certain structural design, the sealing failure caused by scaling can be reduced
