Suction hose
Mostly used with these hoses are the rubber flange/steel backing flange and the Double Action flange. They can be supplied in any size, and depending on application, with 100% vacuum capability and high implosion pressures. For use with gimbals and in the ladder of cutter dredgers we can furnisch you with small bending radius suction hoses. Trelleborg Velp has just delivered the suction hoses for the largest trailing suction hopper ever built. In some applications heavy spring steel spirals are used to prevent the hose from kinking. We never use ordinary (thus cheaper) galvanized wire of suction hoses. Ordinary wire cannot cope with the high dynamic loads which occur for example when your suction pipe gets ocstructed. Trelleborg Velp spring steel spirals absorb these peak loads without the risk of collapsing. Heavy duty big bore suction hoses come equipped with rigid stell rings. This allows for smooth bending of the hose.
