Hongruntong Marine shore-based discharge hose pipe is a lightweight flexible rubber pipeline specially developed for nearshore port dredging, dock sediment cleaning and short-distance shore-water connected slurry discharge operations. The product covers small and medium caliper specifications from DN80 to DN400, with single-section length of 2 to 8 meters and rated working pressure of 0.8MPa to 1.6MPa, which is precisely matched with the working load parameters of small and medium-sized dredging equipment and port fixed pump station systems.
Adopting a compact multi-layer vulcanization structure, the product is composed of medium wear-resistant inner rubber, high-flexibility fiber reinforcement layer, anti-collapse steel wire framework and weather-resistant mixed outer rubber, realizing the integrated balance of lightweight operation, structural stability and cost-effectiveness for nearshore industrial scenarios.
A coastal bulk cargo terminal in Vietnam faces annual sediment silting problems in the harbor basin, which affects the berthing depth of small and medium-sized cargo ships. The client selected Hongruntong lightweight flexible discharge hoses for the port's daily dredging supporting pipeline system.
After implementation, the manual deployment and recovery efficiency improved by 55%, with flexible bending performance adapting to narrow dock transitions and shore-based pipeline height differences. The stable medium wear resistance ensured continuous discharge of port silt with no pipeline damage or leakage during 8-month continuous operation, reducing client's comprehensive labor and equipment costs by 32%.

Compact multi-layer structural layout reduces overall weight by over 25% compared to traditional heavy-duty hoses, enabling manual deployment without crane equipment and improving operational flexibility in narrow dock spaces.
Cost-effective balanced wear-resistant formula optimized for fine silt, port sediment and low-abrasion mixed water media, maintaining stable low wear loss during long-term transportation while eliminating performance redundancy.
Optimized fiber weaving angle and rubber layer matching achieves smaller minimum bending radius, adapting to tight-angle bending and multi-directional layout conversion without permanent deformation or flow channel blockage.
Modified mixed rubber outer protective layer provides excellent resistance to ultraviolet aging, salt spray corrosion and tidal alternating dry-wet fatigue, ensuring long-term stable performance in coastal port environments.
Yes, the product is structurally optimized for frequent operation scenarios with good bending recovery performance and structural stability, meeting repeated use requirements of port regular dredging projects.
The product operates stably from -20°C to 75°C, adapting to high-temperature exposure in tropical coastal ports and low-temperature operation in temperate regions.
Standard flanges adopt universal marine port specifications compatible with most small and medium-sized dredgers. Special flange sizes can be customized according to client equipment drawings.
Clean internal medium after use and store flat in dry, ventilated warehouse avoiding sun exposure and heavy pressure stacking to effectively extend service life.
Under conventional nearshore low-load continuous operation, stable service life reaches 8 to 10 months with low failure rate and simple maintenance.
