Compensation
 

Actually, it plays a part in volume compensation which changes according to the fluid’s different pressure, temperature and flow rate of the service system.

 

As Volume compensating element in gyroscope, power station air cooling system single hinge compensator, vacuum pipe double-hinge expansion joint in air-cooled island, boiler and pressure vessel.

Double-hinge expansion joint


 

The compensator is consist of adapter, corrugated pipe, and a pair of hinge which connects to adapter, the designed hinge and pin roll could bear the thrust made by internal and external pressure on the compensator. It can absorb uniplanar angular displacement, need two or three units of compensators combined while absorbing the displacement.
