Product details

Marine suction and discharge rubber floating dredging hose is a type of hose that is used for the transportation of slurry, mud, and other materials in dredging operations. It is made of high-quality synthetic rubber and reinforced with multiple layers of high-strength steel wire. The hose is designed to be flexible and can be used in a wide range of applications, including river and harbor dredging, offshore oil and gas exploration, and mining operations. The floating design of the hose allows it to float on the surface of the water, making it easy to maneuver and position.

Dredger Pipeline

Dredger Pipeline

The assemblies on land for dredging conducts mainly by HDPE Pipe with several steel accessories like bends, hydraulic valves, ball joints, diffusers, spreaders and reclamation boxes.

HDPE Pipe

Floating/Shore HDPE Pipe

Floating/Shore HDPE Pipe is made from high density polyethylene resin. It has high rigidity and toughness, with little resistance but high mechanical strength. It has ultra-high wear resistance, abrasion degree is 4-8 times of steel pipe, useful life can reach more than five years. It is very light so it's easy to install and transport and then save construction time.
Total Length ≤12m; Working pressure and inner diameter can be customized.

HDPE pipes, equipped with or without collars and swivel flanges. Ideal in combination with pipe floater for slurry and sand dredging applications.
