Animation Uni-Combigrip Axial Restrain Coupling

UNI-Combigrip couplings are used to connect plastic pipes to metal pipes. The specially designed plastgripring with its distinctive cut teeth that engages into the plastic pipe without damaging the surface of the plastic pipe at one end of the coupling, and a gripring with special design teeth with a progressively anchoring effect with ball solution at the other end of the coupling. The design of the two rings ensure even distribution of pressure over the pipe surfaces.

When the axial tensile load of the pipe is increasing by internal pressure or external influence, specially shaped balls brought in at the back of the metal pipe will push hardened teeth into the pipe surface. The depth of the anchoring’s teeth under pressure is approximately 0.1 to 0.3 mm. With the use of this method it is possible to achieve improved anchoring behavior on hard surfaces like thin-walled stainless steel or cast-iron pipes. By the oblique angle of the teeth, anchoring is obtained by coated surfaces like hot dip galvanized steel tube.

Not only the teeth are innovative. The UNI-Combigrip’s gasket solution is patented and uses the latest techniques in sealing. During installation of the coupling compensation beads/grooves are used, therefore the stainless steel insert that is needed in gaskets used by competitors is no longer needed what solves the corrosion problem that comes with these strip inserts. The strip insert is now only needed in vacuum pipes.

UNI-Combigrip couplings are available in sizes from 39 mm to 165 mm. All models are suitable for new installations and retrofit, whether on a building, ship or process plant. The UNI-Combigrip range offers a pipe coupling system that accommodates angulation, vibration and vacuum.
