As an essential component of dredging, suction dredging hose plays a very important role with cutter suction dredge or large trailing suction hopper dredge.
To guarantee the quality, ordinary galvanized wire has never been used for it can?t withstand high dynamic loads. Our reliable suction hose employs heavy spring steel to absorb impact roads caused by water wave. Large bore suction hose are equipped with rigid steel rings for flexible bending.
