Direct buried bellows compensator is mainly used for axial direction compensation, and it has strong bending resistance, so no need to worry pipeline sinking will affect it. At the protection of compensating shell and guide sleeve, it can realize flexible compensation.
Installation note:
Installation note:
In order to realize its compensation effect, must set fixed bracket at compensator both ends, to prevent pipeline internal pressure pushing force affect its stretching.
Compensator one end (means the dead end of the compensator which used for uni-directional compensating) need to be near the fixing bracket, use the active end to compensate pipeline.
Set the two fixing brackets distance according to compensation amount. Normally the compensation amount is not more than pipe diameter.
When test pressure, compensator should not have stretching.
