Floating hoses

Floating hoses are installed on the supporting main line of the dredger and are mainly used for floating pipelines. They are suitable for ambient temperatures ranging from -20℃ to 50℃, and can be used to convey mixtures of water(or seawater), silt, mud, clay and sand.

A floating hose is composed of lining, reinforcing piles floatation jacket, outer cover and carbon steel fittings at both ends. Due to the unique design of the built-in flotation jacket, the hoses are buoyancy and can float on the water surface no matter in an empty or working state. Therefore, the floating hoses are not only have the characteristics such as pressure resistance, good flexibility, tension resistance, wear resistance, shock absorption, aging resistance, but also has floating performance.

According to the different positions, functions and buoyancy distribution of the pipeline, various functional floating hoses are available, such as full floating hose, tapered floating hose, etc.

Buoyancy

The floating hoses can be configured with different buoyancy to meet different application requirements. “SG xx” is often used internationally to distinguish the buoyancy of floating hose, such as “SG 1.8”, “SG 2.0” and so on. “SG xx” indicates that the maximum density of the conveying material of the hose is xx t/m³, that is , the floating hose does not completely submerge into the water when conveying the materials of this density. The hose buoyancy is configured according to the needs of operating environment and conveying capacity of the hose.

Technical Parameters

Dredging Rubber Hose Advantages

1. With highly wear-resistant lining, with wear-warning color layer.

2. With outer cover resistant to weather and UV.

3. With wide range of buoyancy levels.

4. With good bending performance.

5. With high tensile strength and sufficient stiffness.

APPLICATION:

Depending on the function, there are two kind dredging hose, one kind is discharge hose and the other kind is suction hose. Duo to the continuous development of dredging vessel, Trailing Suction Hopper Dredger (TSHD) and Cutter Suction Dredger (CSD) are the mainly dredgers in the world. Duo to complex construction conditions including coral, reef rock, granite and others, the armored discharge hose effectively solves these problems. The floating hose provide installation efficiency and reduces the impact of wind and waves on the offshore projects.
