Grip collars

PAM SMU / ENSIGN®

In sections where thrust efforts have to be addressed - changes of direction and gradient, branches and plugs - or wherever there could be accidental overpressure due to overloading or saturation of the sewer main, the pipework leaktightness and stability call for joints able to withstand end thrust efforts, be they high pressure couplings or combinations of couplings and grip collars. In the second case, the assembly performance is defined by the weakest of the two products.

PAM SMU / ENSIGN®

Anchoring grip collars to secure PAM SMU/ ENSIGN pipeworks

 

Designed by SAINT GOBAIN PAM, the PAM grip collar combines outstanding mechanical properties with very good pressure performance, same as those of the PAM designed couplings, and over the Standard requirements.

The thorough selection of the steels also ensures a very good corrosion resistance.

This grip collar tightens “null gap”, there is no use checking the torque.

Grip collars for expansion plugs
PAM SMU / ENSIGN®

Benefitting from the same design as the PAM grip collars, the PAM grip collars for expansion plugs are specially designed to secure them.
