Dredge Hose – Floating, Suction and Dredge Types for Functional Applications
Compared with sandblasting hose, which has smaller diameters for derusting, the dredge hose has large diameter which ranges from 6" to 36". It is widely used for seawater, sand and other materials dredging in various applications.

Dredge hose has similar structure with other suction and discharge hoses, which contains inner layer, reinforced layer and outer layer.

Inner layer. Black and smooth synthetic rubber for abrasion and wear resistance and clogging resistance.
Reinforcement layer. Cord thread and steel spiral wire for high tensile strength and kinking resistance.
Outer layer. Smooth or corrugated synthetic rubber for wear and abrasive resistance. Additional, it has excellent weather and chemical resistance performance in corrosive environments.
According to the structure and function, the dredge hose has slightly different structure, they can be divided into three types:

Floating dredge hose
Suction dredge hose
Discharge dredge hose
Floating dredge hose

Floating dredge hose features self-floating on the water.
Structure.

Inner layer. high quality wear and abrasion resistant rubber.
Reinforcement layer. Several layers of cord threads and spiral wire reinforcement.
Filling layer. It is particularly designed for the floating dredge hose. It is filled with PEF (polyethylene foaming). It can support the dredge hose floating on the water.
Outer layer. High quality SBR rubber and other synthetic rubber material.
Features

Special design for self-floating performance on the seawater.
Synthetic rubber material is highly resistant against weathering, UV ,salty and ozone.
Smooth SBR inner rubber supplies wear resistance and no-plugging performance.
Small bending radius. In working condition, the bending angle is from 0° to 45°.
Working temperature ranges form -25 °C to 80 °C.
Safety factor: 4:1.
Application

The floating dredge hose is connected with floating dredge hoses through rubber or steel flange. It is widely used for port and dock discharging of seawater, slit, sand and other dredging applications.

Advantages of dredge hose

The dredge hose features high strength, and flexibility. it is abrasion and wear resistant to ensure the long service life. The rubber hose has excellent salty, weather and other chemical resistance performance to ensure the good performance in the corrosive environments. Flange connection method makes it easy for installing and replacing.

Applications of dredge hose

The dredge hose is used for the engineering of waterway clean-ups, dredging, pumping sand, land reclamation, port expansion, and other mud or mortar conveying operations.
