Dredge suction & discharge hose can be used to deliver many kinds of abrasive materials, such as slurry, sand and gravel. It is also used to handle seawater, and this is seawater suction & discharge hose. It is mainly used for seawater suction, delivery and discharge. It is composed of three parts: tube, reinforcement and cover. Tube is made from high quality synthetic rubber (NR, SBR and BR), making hose resistant to seawater and corrosion. Reinforcement is made from multiple layers of high tensile spiral steel wires, making hose resistant to kink, bending and wave in handling seawater. Besides, the hose is suitable for high working pressure environment and it has solid structure because of the high tensile reinforcement. Cover is made from high quality synthetic rubber (NR, SBR and BR), making hose resistant to abrasion, corrosion, seawater, heat, weather, ozone and aging. The hose is very flexible and it is easy to install & dismantle, because it is connected to pipeline tightly by flange.

A seawater suction and discharge hose is on the ground.

Seawater suction and discharge hose can be used to deliver seawater because of its solid structure.A seawater suction and discharge hose with black cover is on the ground.

Seawater suction and discharge hose is easy to install and dismantle because of the flanges on the ends.

The details of seawater suction & discharge hose:

Structure: composed of three parts: tube, reinforcement and cover.

Tube: synthetic rubber, NR, SBR or BR, making hose resistant to abrasion, corrosion and seawater.

Reinforcement: multiple layers of high tensile spiral steel wires, making hose have solid structure and resistant to kink and high pressure.

Cover: synthetic rubber, NR, SBR or BR, making hose resistant to abrasion, corrosion, seawater, heat, weather, ozone and aging.

Working temperature: 20 °C to 80 °C.
