Hongruntong Marine's Dredge Pipeline is a heavy-duty, engineered rubber conveying system specially developed for high-intensity sand, silt, gravel, and slurry transportation in dredging, land reclamation, port construction, river regulation, and mining tailings delivery.

Built with a multi-layer composite structure consisting of an ultra-wear-resistant inner rubber layer, multi-strength steel wire reinforcement, and a weather- and corrosion-proof outer protective layer, this pipeline provides outstanding durability, pressure stability, and operational safety in long-term, harsh working environments.

Available in diameters from 200mm to 1200mm and customizable lengths up to 12 meters, the pipeline supports high-concentration slurry delivery with solid content up to 75% and flow velocities up to 7m/s, making it highly adaptable for suction and discharge systems on large and medium-sized dredgers.

In 2023, an Australian marine engineering company undertook a coastal navigation channel improvement project, requiring continuous dredging and sediment transportation in an environment with strong waves, high salinity, and coarse sandy seabed.

Hongruntong Marine supplied 950 meters of 800mm diameter Dredge Pipeline with a 16bar working pressure rating, customized for high-wear and high-corrosion conditions. During the five-month project, the system operated continuously with zero leakage, joint failure, or unexpected downtime.

Compared with the client's previous equipment, daily conveying capacity increased by 26%, maintenance frequency decreased by more than 50%, and overall project cost was reduced by 17%.
