Self-Floating Hose
A self-floating dredge hose is a specialized type of hose used in dredging operations. It is designed to be buoyant and flexible, allowing it to float on the water's surface while carrying dredged materials.
Hongruntong Marine Dredge Floating Hose is specifically designed for the transportation of sand, slurry, mud, and gravel in dredging and reclamation projects. It is built to float on water, maintaining flexible and efficient pipeline alignment even in dynamic offshore or nearshore environments.
Constructed with wear-resistant rubber and reinforced with high-tensile synthetic cord and embedded steel rings, our floating hoses are equipped with durable foam-filled floatation collars to ensure positive buoyancy and long service life.
Key Features & Benefits

Flexible & Easy to Handle
Hose retains flexibility over time and is easy to install and reposition during operations.
