COUPLERS FOR SHOULDERED END PIPE – ALVENIUS K10 / KLAMBON / VICTAULIC TYPE
Each coupling / clamp consists of two identical curved housing, gaskets, nuts and bolts. The housing are manufactured from the Ductile Iron Casting, the Gasket is from Nitrile / Natural Rubber and the Nuts and Bolts are made from steel as per 4.6 Grade. The head of the bolt is oval necked to fit square shaped holes in the housing. The Coupler castings are Painted / Galvanized.

Daman Pipe are manufacturer and exporter of Splitset to the mining sectors in Africa.
Split Sets are manufactured with 2 parts, a tube and matching domed bearing plate. The high Strength steel tube is slotted along its length. One end is tapered for easy insertion into a bearing plate. With the bearing plate in place, the tube is riven into a slightly smaller hole, using the same standard percussion drill that made the hole. As the tube of the split set slides into place, the full length of the slot narrows, causing radial pressure to be exerted against the rock over its full contact length.
