Product Description

Full Floating Hose (Floating Discharge Hose / Dredging Hose)

A Full Floating Hose is composed of lining, reinforcing plies, flotation jacket, outer cover and carbon steel fittings at both ends. The flotation jacket adopts an unique design of integrated built-in type, which makes it and the hose become a whole, ensures the buoyancy and its distribution. The flotation jacket is made of closed-cell foaming material, which has low water absorption and ensures the stability and sustainability of hose buoyancy.

Specification

Applications

Floating Hoses are mainly uses in floating pipelines, they can be connected together to form a independent floatingpipeline for material conveying, or can be spaced connected with steel pipes. But pipelines composed entirely offloating hoses perform better in application compared with pipelines composed of both steel pipes and floating hoses. itis generally not recommended to adopt the mode of combining floating hoses and steel pipes, because this will causepartial excessive wear of floating hoses and reduce its service life, Floating Hoses may become bent after a long timeof use. Such mode should be adopted sparingly.

Features
(1)With highly wear-resistant lining, with wear-warning colour 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

Illustration

Dredging Hose

This detailed image illustrates the precise deployment locations of various specialized dredging hoses within a comprehensive marine operation. It maps the entire sediment transport route, starting with the Sinking Hose resting on the seabed for initial material intake, often near a cutter. Jet Water Hoses are strategically positioned to fluidize compacted sediments near the suction point. The critical transport path is formed by connected Section Hoses, comprising the main pipeline. Buoyancy is managed using Floats supporting sections requiring surface positioning. Tapered Floating Hoses facilitate smooth connections between pipes of differing diameters or at transition points. Where the seabed slopes significantly, Slope Adapted Hoses accommodate these contours without excessive stress. The majority of the surface pipeline often consists of Full Floating Hose sections, kept buoyant along their entire length. Approaching the discharge location, Discharge Hoses handle the final transport of the sediment-water mixture. Finally, Bow Blowing Hoses are specifically deployed for direct connection to barges or vessels, enabling precise sediment placement during discharge operations. The visualization clearly highlights how each hose type – from sinking intake to floating transport to specialized discharge – is optimally positioned to handle depth variations, seabed topography, buoyancy requirements, connection challenges, and the final placement of dredged material, ensuring efficient and effective sediment transfer throughout the system.
