SafetyA dredger hose from Trelleborg Velp is a reliable product all along the line. This reliability is guaranteed in a number of ways, starting with the concept. Because of their high level of wear resistance and flexibility, rubber material handling hoses are, by nature, ideal transport lines.Hoses from Trelleborg Velp have proved to have a very long life in practice, even when pumping highly abrasive media. Overdimensioning is added to this excellent starting point in the design phase; we always make a dredger hose much thicker than specified. This safety margin is used to give the hose an additional shield against unforeseen circumstances. Other guarantees of safety and reliability are provided by our production control and test facilities. We can issue test reports for our products at the customer‘s request. But most of the tests which we carry out are intended for our own research. We also want to be sure at all times that we adequately satisfy all test and inspection requirements throughout the world.
