Product Introduction:
Discharge suction rubber hose is part of dredge pipeline for dredger, usually with the steel
pipe or HDPE pipe connected in one set of pipeline. We know that
the general steel pipe and HDPE pipe do not have much flexibility,
while the discharge rubber hose has such characteristics. In the
working environment with high wind and waves, the discharge rubber
hose can rely on its own softness to offset part of the wind, so as
to ensure the safety of the whole pipeline. Besides, Dredging
hoses' wear lining is super wearable and suitable of various of
dredging objects. This allows for smooth bending of the hose. It
can be equipped with fixed steel flanges, loose steel flanges or
rubber flanges.
The rubber suction and discharge hose has an inner rubber layer,
multiple layers of cloth or cord and spiral steel wire are used as
the reinforcement layer, and the outer rubber layer is determined
according to the use of the pipe. These materials provide resistance against the abrasion and
chemical attack from the transported mud or slurry
Outer Cover: Anti-aging and Abrasion Resistant Synthetic Rubber (SBR or NR)
Reinforcement Layer: High Strength Synthetic Textile Cords or Steel Wire Helix
Inner Tube: Anti-aging and Abrasion Resistant Synthetic Rubber



Applications:
Suction and delivery hose is widely used in dredging engineering
dredging vessels to clean up sludge, suction and discharge
seawater, sand, sewage, sludge and agricultural irrigation.
Large diameter mud suction and discharge rubber hoses are also used
for transferring drilling mud and other fluids between offshore
drilling platforms and onshore storage tanks.
