Dredge Self-Floating Rubber Hose

Dredge Self-Floating Rubber Hose

Application

The dredge self-floating rubber hose is an essential component of any dredging operation, providing a reliable and efficient means of transporting dredged materials from one location to another. It is available in various diameters and lengths, depending on the specific needs of the dredging project. The hose is designed to float on the water surface and is made of high-quality rubber materials to withstand the abrasive nature of the materials being transported.
The self-floating capability of the hose is achieved through the use of closed-cell foam flotation devices that are integrated into the hose's structure. These flotation devices are placed at intervals along the length of the hose and ensure that it remains afloat and above the water surface, even when fully submerged.
