Customizable Flanged Dredge Pipeline High Abrasion Resistance For Slurry Transport

Hongruntong Marine's Dredge Pipeline is a heavy-duty, high-performance rubber conveying pipeline specially designed for long-distance, high-capacity transportation of sand, slurry, gravel, and sediment in dredging, land reclamation, port construction, river management, and mining applications.

Constructed with a multi-layer composite structure including an ultra-wear-resistant inner rubber layer, multi-stage high-tensile steel wire reinforcement, and a weather-resistant anti-corrosion outer protective layer, this pipeline provides exceptional durability, pressure stability, and operational safety in harsh marine and industrial environments.

Available in diameters from 150mm to 1200mm and customizable lengths up to 12 meters, the dredge pipeline supports slurry concentrations up to 80% and flow velocities up to 7.5m/s, making it suitable for suction and discharge systems of various large and medium dredging equipment.

In 2024, a large Middle Eastern construction group carried out a port expansion project, requiring high-intensity dredging and sand transportation in a high-temperature, high-salinity coastal environment. The project faced challenges including continuous strong sunlight, coarse sand particles, and long working hours.

Hongruntong Marine supplied 1,200 meters of 1000mm diameter Dredge Pipeline with a 18bar working pressure rating, customized for high-temperature and high-abrasion working conditions. During the six-month project, the system operated continuously with no leakage, joint damage, or unexpected shutdowns.

Compared with the client's original equipment, daily transportation volume increased by 30%, maintenance frequency decreased by 60%, and overall project cost was reduced by 20%.
