| Product List |
Floating Dredge Hose is an advanced marine engineering product designed for continuous, high-capacity slurry transport in offshore, coastal, and port dredging operations. Its multi-layer construction consists of a high-abrasion synthetic rubber inner lining, reinforced carcass layers made of high-strength textile cords or steel wire, and a weather-resistant outer cover that protects against UV radiation, ozone, saltwater, and chemical exposure.
Integrated closed-cell foam flotation provides stable buoyancy, preventing sagging, misalignment, and stress accumulation on joints, even in high-wave and tidal conditions. The hose is capable of handling dense and abrasive slurry, including sand, silt, gravel, and mixed sediments, while maintaining optimal flow efficiency.
During the construction of an offshore wind farm in Northern Europe, a 24,000 DWT trailing suction hopper dredger was used to prepare the seabed for turbine foundations over a 3.5-kilometer distance. The operation involved transporting a mix of sand, gravel, and silt under strong currents and cold water conditions.
Hongruntong Floating Dredge Hoses were deployed to form the floating discharge pipeline. The abrasion-resistant inner lining handled coarse sand and gravel without significant wear, while the closed-cell foam flotation maintained consistent buoyancy and alignment despite strong tidal currents.
The project achieved a 29% increase in dredging efficiency, significantly reduced downtime, and lowered maintenance requirements. Operators reported safer working conditions due to stable pipeline alignment, and the modular design enabled rapid replacement of hose segments.

Note: Various sizes can be customized according to the requirements.
The inner tube is formulated with high-performance synthetic rubber capable of resisting continuous friction from dense, coarse slurry, including sand and gravel. This ensures extended service life, consistent slurry flow, and reduced maintenance in demanding offshore and coastal operations.
The integrated flotation layer provides consistent buoyancy over the hose's operational life. Unlike traditional materials, the foam does not absorb water, preventing sagging, reducing mechanical stress on joints, and enhancing operational safety.
The reinforcement carcass, made from high-tensile textile cords or steel wire spirals, provides exceptional tensile strength and pressure resistance. This allows the hose to transport heavy slurry loads over long distances without deformation or failure, even under high-pressure pumping systems.
Despite its robust construction, the hose retains flexibility for curved or uneven waterways. Standardized flange or quick-coupling connections allow rapid assembly, disassembly, and replacement of individual segments, reducing downtime and labor costs.
Yes, reinforced layers and foam flotation ensure stable performance in strong currents, waves, and high-pressure slurry transport.
Hoses can be designed to withstand pressures up to 30 bar, depending on project specifications.
With proper maintenance and inspection, hoses typically last 3-5 years in heavy-duty dredging operations.
Yes, the durable materials and modular design allow redeployment for repeated use in different projects.
Store in a cool, dry location, away from direct sunlight, chemicals, or sharp objects to preserve material integrity and flotation performance.
