Construction
Parts and materials
Clamp-type repair couplings are designed to repair leaks (fistulas) and local damages (including cracks), as well as for pipe connections during repair and restoration works on water supply and sewerage pipelines made of steel, cast iron, PVC, polyethylene, asbestos cement and chrysotile cement. Connection is carried out by compression method due to tightening of bolts and pressing the inner surface of the coupling to the outer surface of the pipe. The clamp type repair coupling can be used even in the presence of pressure in the pipeline, which allows to speed up the repair and restoration work.
