Relying on bellows' companding and bending, bellows compensators can proceed axial, transverse,

angular compensation. Their functions as follows:

1.   Compensation absorbing pipelines' axial, transverse, angular heat distortion.

2.   Absorbing equipment vibration, reducing the vibration's influence on pipelines.

3.   Absorbing the earquake, ground settlement' s deformation to pipelines.
