Steel bellows introduction:

Steel bellows 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.
Steel bellows working principles:

1) Compensating and absorbing pipeline axial, lateral and angular to the thermal deformation.

2) Absorbing equipment vibration, reducing equipment vibration effects on pipelines.

3) Absorbing earthquake, subsidence deformation of pipeline.

Steel�bellows classification:

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

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

Steelbellows 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.
