Product Details
Light Weight Floating Dredging Hoses
,Pressure Resistance Rubber Dredging Hoses
Dredging Rubber Hose is a high-performance fluid transfer solution specifically engineered for transporting abrasive slurry mixtures in marine dredging operations. Constructed with a multi-layer composite structure, the hose integrates an ultra-wear-resistant inner rubber lining, reinforced carcass layers, and a weather-resistant outer cover. It is capable of handling high concentrations of sand, gravel, and sediment under both suction and discharge conditions.
Available in a wide range of diameters and pressure ratings, the hose is designed to operate efficiently in demanding environments, including offshore dredging, river maintenance, and land reclamation. Its robust yet flexible structure ensures stability under dynamic loads and continuous operation.
With superior resistance to abrasion, pressure, and environmental degradation, this dredging hose significantly reduces maintenance intervals and enhances operational continuity, making it a reliable solution for modern dredging systems.
In a large-scale river deepening project utilizing a trailing suction hopper dredger (TSHD) of 45,000 m³ capacity, the contractor encountered frequent hose failures due to sharp sediment particles and high flow velocity.
Hongruntong Marine supplied heavy-duty dredging rubber hoses with enhanced reinforcement and optimized rubber formulation. The hoses were installed in the discharge system operating at high pressure over extended periods.
Following implementation, the failure rate dropped significantly, and operational uptime increased by 35%. The improved durability reduced replacement costs and minimized downtime, leading to substantial project savings. The client highlighted the product's stability and reliability as key advantages.

The inner lining is engineered using specially formulated rubber compounds with high resistance to abrasion and erosion. This allows the hose to withstand continuous exposure to sharp and coarse materials without significant degradation. The result is a longer service life and improved cost efficiency in demanding dredging environments.
The hose incorporates multiple layers of high-strength reinforcement materials, including steel wire spirals and synthetic fabric. This design ensures excellent pressure resistance and structural integrity, enabling the hose to perform reliably under high-pressure slurry transport conditions.
Designed to maintain flexibility without compromising strength, the hose adapts easily to curved layouts and dynamic movements. This is particularly important in floating pipelines and vessel-mounted systems where constant motion is present.
The outer layer is resistant to UV radiation, ozone, and saltwater corrosion. This ensures long-term durability even in extreme offshore environments, reducing the risk of surface cracking and material degradation.
