The floating dredge hose developed by Hongruntong Marine is specifically engineered for high-pressure slurry transport in demanding dredging environments. Designed to handle dense mixtures of sand, gravel, and sediment, this hose integrates advanced reinforcement technology with superior wear-resistant materials to ensure long-term operational reliability.
The internal lining is manufactured using specially formulated anti-abrasion rubber compounds that significantly reduce material loss caused by high-velocity slurry flow. Multiple reinforcement layers, including high-tensile synthetic cords and optional steel wire spirals, provide exceptional resistance to internal pressure and external mechanical forces.
A key feature of this product is its high-performance integrated flotation system. The buoyancy layer is constructed using high-density closed-cell foam, ensuring stable floating capability even under heavy load conditions. This allows the hose to maintain consistent positioning and alignment, reducing stress on the pipeline system.
During a major port deepening project in the Middle East, a dredging contractor faced significant challenges related to high-density slurry transport. The project involved a large trailing suction hopper dredger with a capacity exceeding 8000 cubic meters, operating under conditions where sand and gravel content in the slurry was particularly high.
Hongruntong Marine supplied a set of high-pressure floating dredge hoses specifically designed for abrasive slurry conditions. The hoses featured an upgraded inner lining with enhanced wear resistance and a reinforced structure capable of handling higher pressure loads.
After installation, the dredging system showed a marked improvement in performance. The hose maintained consistent internal pressure, allowing smoother slurry transport over extended distances. Wear rates were significantly reduced compared to the previous system, leading to fewer replacements and lower maintenance costs.
