Suction Dredging Hose


Suction Dredging Hose also called mud suction & discharge hose, is mainly used for sewage, slurry, seawater and sand suction & discharge in many places. It is also used for flood discharge and port and dock construction. It has excellent flexibility and it is resistant to wave. It is composed of three parts: tube, reinforcement and cover. Tube is made from high quality synthetic rubber, such as NR, SBR and BR, making hose resistant to abrasion and seawater. Reinforcement is made from multiple layers of high tensile spiral steel wires, making hose have solid structure and bear high working pressure. Besides, reinforcement makes hose resistant to bending and fatigue. Cover is made from synthetic rubber, like NR, SBR and BR, making hose resistant to abrasion, corrosion, seawater, heat, weather, ozone and aging. The hose can be connected to pipeline very well, which can reduce the sea wave, so it can deliver medium flows smoothly.

Suction Dredging Hose Construction:

Tube: Abrasive resistant synthetic rubber with high strength breaker plies and coated with a high grade synthetic rubber interior surface.

Reinforcement: High tensile strength fabrics with a steel inner structure. Fully embedded steel wire coils are incorporated to achieve kink, crush and local load resistance.

Cover: Synthetic rubber, resistant to abrasion, weathering, sea water and oil exposure. The cover, which incorporates reinforcing breaker plies is black with a bright orange spiral stripe or coated in tough bright orange polyurethane.

Suction Dredging Hose Application:

Suction dredge hoses are designed for sediment absorption along with dredging ships. It is mainly applied for river and harbor construction, land reclamation and dredging, to extend the distance of the water dredging, The flexible and easily installed dredging hoses are abrasion and kink resistant thanks to the synthetic materials combined with the helix steel reinforcement wire. The smooth interior of the hoses helps prevent clogs and avoids damage from the abrasive materials passing through.

Suction Dredging Hose Characteristic:

● Superior abrasion resistance

● Weather and sea water resistance

● Without kink and crush

● Heavy duty Max working pressure 35bar

● UV resistant cover

Temperature: -25℃ to +80℃(-13℉ to +176℉)
