2. Available in lengths up to11.8 m
3. Suitable for working pressures up to 30 bar
4. Available in either floating or submarine designs
5. Complementary sleeve designs suitable for suction or discharge service
6. Manufactured in accordance with ISO 9001:2000 quality standards (latest edition)

Structure Lining

The synthetic rubber used for the lining of the hoses achieves maximum adhesion that is resistant to corrosion and damage during use.

Reinforcement

Multiple layers of high tensile strength reinforcement materials help prevent fatigue and physical damage, while maintaining flexibility. Fully embedded steel wire coils are incorporated prevent kinking and crushing.

Cover

The outer cover of the rubber hose is resistant to abrasion and wear caused by sea water and oil exposure. It features a bright orange spiral stripe coated in tough bright orange polyurethane.

Advantages

The dredge hose features light weight, high strength and flexibility. It is abrasion resistant, corrosion resistant, ultraviolet resistant and anti-aging. This marine hose can be connected directly through the flange. The transmission efficiency is higher than that of the steel tube by 20%-30% because of its friction coefficient. It can be used for a long term installation in water or on land.

Applications

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.

Our floating dredge hoses are intended for port and dock discharging of seawater, silt, sand and other dredging applications. They are commonly used in part of the construction process of docks and ports.

Features

1. The outer cover is made from a rubber compound that is highly resistant against weathering, UV and Ozone.
2. Wear indicator layers can be implemented in the dredge hoses which transport abrasive media.
3. A single foam floating layer prevents water absorption. The hose emergence above the water is not less than 20% of the total volume.
4. Inner layer: high quality, excellent abrasion resistant rubber.
5. Custom flanges available.
6. Bending angle: in working conditions, the bending angle is from 0° to 45°.
7. Working temperature range: -25ºC to 80ºC
8. Safety factor: 4:1

We can supply a wide range of floating and submarine (non-float) rubber flexible hoses. Internal diameter (ID) options include, 35"(900 mm), 20"(500 mm), 16"(400 mm), 12"(300 mm), 10"(250 mm), 8"(200 mm) to 6"(150 mm). Other diameters and special requirements can also be supplied upon request and availability.
