Metal bellows expansion joint 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.

Metal 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.
