stainless Steel bellows expansion joint introduction:

stainless Steel bellows expansion joint are also named for the expansion joints, Bellow expansion joint, bellows compensator, is a kind of flexible, thin wall, a transverse corrugated device with telescopic functions, it is made up of metal corrugated pipe and components. Bellows compensator’s working principle is mainly using their elastic scaling, to compensate the axial, angular, lateral and combined compensation due to pipes’ thermal deformation, mechanical deformation and all kinds of mechanical vibration, the role of compensation has pressure, sealing, corrosion resistance, temperature resistance, impact resistance, anti-vibration noise reduction function, it could reduce the pipe deformation and prolong the service life of pipelines.

stainless Steel bellows expansion joint classification:

1)  According to whether can absorb piping within the medium pressure generated by the thrust (blind plate force), steel bellows expansion joint can be divided into no constraint bellows expansion joint and constraint bellows expansion joint;

2)    According to the displacement type of bellows expansion joint, it can be divided into axial type, horizontal type bellows expansion joint, and angular type bellows expansion joint and pressure balance type bellows expansion joint.

 Stainless Steel bellows expansion joint application:

1) Large deformation and the deformation but spatial location limited pipeline.

2) Large deformation and displacement but low pressured large diameter pipes.

3) Be restricted to take over the load equipment.

4) Asked to absorb or high frequency mechanical vibration of pipeline.

5) To absorb seismic or foundation settlement of the pipeline.

6) Shock absorption pipeline pump exports.
