Angle Pad Coupling

Rigid Couplings can not enable the connection system to be flexible, and the couplings are integrated with steel pipes after they are fastened. If the sling has a bigger span, the pipes will support the connection depending on their own rigidity.

 

Flexible Couplings can enable the connection system to be flexible ,it allows the steel pipe has a certain angle deviation and relative deviation .There are some clearance between the ends of two steel pipes in order to suit the expansion and shrinkage of the pipelines. The pipe couplings should maintain the normal working condition under the maximum allowable deflexion and dislocation .Flexible Couplings can endure a certain terminal load, which refers to the load along the pipe axis to be borne by coupling grooves.
