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.
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.
Our discharge dredge hose is used for port and dock discharging of seawater, silt, sand and other dredging materials. The discharge hose features excellent stiffness and resistance to external physical damage.
Lining
Synthetic abrasive resistant rubber with high strength breaker plies coated with high grade synthetic rubber to achieve maximum adhesion of the lining to the hose carcass.
Suction dredge hoses are designed for silt conveyance dredging operations. The flexible and easily installed dredging hoses are abrasion and kink resistant thanks to the synthetic materials combined with the helix steel reinforcement wire. The smooth interior of the hoses help prevent clogs and avoids damage from the abrasive materials passing through.
Our armored hoses are reinforced with HB steel rings and are suitable for dredging operations that involve highly abrasive materials such as cape rock, coral, limestone and other damaging materials. The flexibility and strength of armored hoses are absolutely necessary for dredging projects in order to minimize downtime.
