Dredging projects can be divided into several types, including capital construction dredging project for port and shipping lane construction, maintenance dredging to the operated port and shipping lane to guarantee enough navigation dimensions, environmental dredging for the silt cleaning of river, lake and sea, dredger filling projects to strength the coast protection or land reclamation. So silt dredge hose is need in these projects, which is mainly used for the suction and discharge of silt.
Silt dredge hoses, also called slurry dredge hose, are usually installed on the two sides of the dredge pump to suck and discharge silt. They are easy to install and remove due to the unique construction of flanges on the each end of hose. Silt dredge hose is very flexible and stable, and it can reduce the vibration caused by storm and water movement. It is highly resistant to abrasion and aging.
Silt dredge hose consists of tube, reinforcement and cover. The tube is made from the mixture of natural rubber and synthetic rubber, mainly EPDM, making the silt dredge hose resistant to abrasion, corrosion and aging. Reinforcement of silt dredge hose is made from multiple synthetic fabrics with spring helix steel w ire, making the hose have very high tensile strength and have the ability of absorbing shock and vibration. The cover is made from SBR, which makes silt dredge hose resistant to cut, abrasion, corrosion, weather, ozone, sunlight and aging.
Many silt dredge hoses are on the ground

Details of silt dredge hose:
Structure: silt dredge hose is composed of three parts: tube, reinforcement and cover.
Tube is made from the mixture of high quality EPDM and natural rubber, making the silt dredge hose resistant to abrasion and corrosion.
Reinforcement is made from spring helix steel wire with multiple synthetic fabrics, providing full vacuum, kink resistance and vibration dampening.
Cover is made from high quality SBR for abrasion, weather, ozone, aging and cut resistance or high quality neoprene for seawater, ozone and sunlight resistance.

Dredge hose can be used to handle many types of media such as slurry, silt and sand for its excellent abrasion resistance. And it is also used to handle seawater. This is seawater dredge hose. It is mainly used for the suction and discharge of seawater. Our seawater dredge hose is composed of three parts: tube, reinforcement and cover. The tube is made from the blend of EPDM and natural rubber, which makes the seawater dredge hose highly resistant to abrasion, corrosion, aging and weather. So it can transport the corrosive medium - seawater. The reinforcement is made from spring helix steel wire with multiple synthetic textile, making the seawater dredge hose resistant to kink. And the reinforcement provides full vibration dampening. The cover is made from super high quality neoprene, which makes the seawater dredge hose resistant to corrosive salt water, cut, abrasion, weather, ozone and aging. Our seawater dredge hose is designed specially to handle seawater, so our engineers choose appropriate materials for the hose. Therefore, it can be competent the job well. Besides, the diameter, length and tube thickness of our seawater dredge hose can be customized according to your requirements. A seawater dredge hose with red flanges. Seawater dredge hose.
