Floating Dredge Hose is a high-capacity, heavy-duty marine pipeline designed to transport slurry efficiently across water surfaces in demanding dredging and offshore engineering operations. Its multi-layer construction integrates a wear-resistant inner tube, high-strength textile or steel reinforcement layers, and a durable outer cover resistant to UV, ozone, and saltwater corrosion. The hose features a closed-cell foam flotation system, ensuring stable buoyancy, preventing sagging, and reducing stress on pipeline joints, even in dynamic tidal and wave conditions.

This hose is optimized for handling abrasive and high-density materials, such as sand, gravel, silt, and dredged sediments. Its inner lining is engineered to minimize wear and friction, prolonging the hose's service life and maintaining flow efficiency. Reinforced layers allow operation under high-pressure pumping systems and provide structural stability during bending, twisting, and torsional stress. The hose's modular design enables rapid installation, segment replacement, and operational flexibility, making it suitable for ports, rivers, offshore reclamation, and industrial dredging projects.

In a South American river deepening project, a 15,000 DWT cutter suction dredger was tasked with increasing the depth and capacity of a major navigable channel. The project required continuous slurry transport over a 2.5-kilometer floating pipeline through fluctuating river currents and variable sediment compositions, including coarse sand, mud, and debris.

Hongruntong Floating Dredge Hoses were deployed to ensure continuous operation. The abrasion-resistant inner lining resisted wear from mixed sediments, while the closed-cell foam flotation system maintained pipeline alignment despite strong currents. The multi-layer reinforcement allowed the hose to handle the high-pressure slurry flow without deformation or fatigue.

The use of Hongruntong hoses resulted in a 32% improvement in dredging efficiency compared to previous operations. Maintenance requirements decreased significantly due to the hose's durability, and operational downtime was minimized. Operators highlighted the hose's stability, ease of installation, and resilience under variable river conditions, confirming its suitability for long-term deployment in inland waterway dredging.

• Exceptional Resistance to Abrasion and Erosion - The inner lining of the hose is made from advanced rubber compounds, providing superior resistance to erosion from high-density and coarse slurry. This ensures consistent performance, extended service life, and reduced maintenance in projects involving abrasive materials.
• Closed-Cell Foam Buoyancy for Reliable Floatation - The integrated foam layer guarantees consistent flotation, maintaining pipeline alignment and minimizing sagging. This feature reduces mechanical stress on hose joints and improves operational safety in both offshore and riverine environments.
• High-Strength Reinforcement Layers - Multiple reinforcement layers provide excellent tensile strength and pressure resistance, allowing the hose to handle heavy slurry loads and high-pressure pumping systems without deformation or structural failure.
• Flexible and Modular for Ease of Use - The hose retains flexibility for deployment in curved or uneven waterways. Standardized flange or quick-coupling connections allow for easy assembly, disassembly, and replacement of individual segments, minimizing downtime and labor costs.

• River and Inland Waterway Dredging - Transport dredged materials efficiently in rivers and canals, maintaining navigable channels and improving flood control capacity.
