| High Light | UV Resistant Floating Dredge Hose ，Floating Dredge Hose Corrosion Proof | ||
UV Resistance Saltwater Corrosion Proof Long Service Life
Floating Dredge Hose is specifically engineered for demanding marine dredging operations where continuous slurry transport, structural reliability, and environmental resistance are critical. The hose is constructed using multi-layer synthetic rubber combined with high-tensile reinforcement fabrics or steel wire spirals, ensuring exceptional mechanical strength and flexibility.
The outer floating layer is composed of closed-cell foam, which provides stable buoyancy and prevents water absorption, allowing the hose to maintain optimal positioning on the water surface even under harsh sea conditions.
Designed to handle abrasive mixtures such as sand, silt, and gravel, the inner lining utilizes advanced wear-resistant rubber compounds that significantly extend service life. The hose is capable of withstanding high working pressures and dynamic loads generated by dredging pumps and wave motion.
In a large-scale coastal reclamation project located in the Middle East, a fleet of 18,000 DWT cutter suction dredgers was tasked with transporting high-density sand slurry over a distance exceeding 2 kilometers. The project faced extreme environmental challenges, including high salinity, strong UV radiation, and ambient temperatures exceeding 45°C.
Hongruntong Floating Dredge Hoses were selected due to their proven durability and resistance to harsh marine environments. The hoses were integrated into a floating pipeline system operating continuously under high-pressure conditions. During the project, the hoses demonstrated excellent resistance to thermal degradation and maintained structural integrity without cracking or deformation.
Operational efficiency improved significantly, with uninterrupted slurry transport reducing project timelines by approximately 15%. Maintenance intervals were extended due to the hose's superior abrasion resistance, lowering overall operating costs.

Note: Various sizes can be customized according to the requirements.
The inner tube is formulated with advanced synthetic rubber compounds designed to resist severe abrasion caused by sand, gravel, and other solid particles. This enhanced wear resistance significantly extends service life, reducing replacement frequency and operational downtime.
The high-performance closed-cell foam flotation layer ensures consistent buoyancy throughout its service life, preventing water ingress and maintaining proper pipeline alignment under dynamic wave conditions.
Multiple plies of synthetic fabric or steel wire spirals provide excellent tensile strength and pressure resistance, allowing safe operation under high-pressure pumping systems and mechanical stresses.
Excellent flexibility adapts to varying operational conditions, while standardized flange or coupling systems enable quick installation and removal, reducing labor requirements and improving efficiency.
The hose is available in a wide range of diameters, typically from 150mm to 1200mm, and can be customized according to project requirements.
The hose is designed to withstand both high and low temperatures, maintaining flexibility and structural integrity even in extreme environmental conditions.
Yes, it is specifically designed for long-distance applications and maintains consistent flow performance across extended pipeline systems.
The hose can be equipped with flange connections or quick-release couplings, depending on operational needs.
Regular inspections are recommended during operation to ensure optimal performance, especially in high-abrasion environments.
