Hongruntong Marine's Dredge Pipeline is a high-performance, heavy-duty rubber pipeline system engineered for demanding slurry, sand, and sediment transport applications in marine dredging, port construction, and land reclamation projects. Manufactured with multi-layered premium natural rubber compounds, high-tensile steel wire reinforcement, and wear-resistant outer cover, this pipeline delivers exceptional durability, flexibility, and pressure resistance for continuous operation in harsh offshore and onshore environments.
In 2024, a leading European dredging contractor was tasked with deepening the Port of Rotterdam's main navigation channel from 14.5m to 17.5m to accommodate post-Panamax container vessels. The project required a reliable, high-volume slurry transport system capable of handling 20,000+ cubic meters of sand and silt per day.
Hongruntong Marine supplied 800 meters of 900mm diameter flanged Dredge Pipeline with a 16-bar pressure rating. The pipeline's wear-resistant inner liner and steel wire reinforcement allowed continuous operation at 6m/s flow velocity, with zero leaks or structural failures over the 6-month project duration. The solution reduced maintenance frequency by 60% and increased daily slurry transport volume by 25%, cutting overall project costs by 18%.

Our standard Dredge Pipeline is available in working pressure ratings from 6 bar to 25 bar, with custom designs available for higher pressure requirements. Each pipeline is hydrostatically tested to 2x the working pressure before delivery.
Yes, we offer specialized floating Dredge Pipeline systems with integrated buoyancy modules, designed for offshore dredging operations with the same high-abrasion inner liner and steel wire reinforcement.
Service life depends on application and operating conditions. In standard sand dredging, typical service life is 3-5 years; in high-abrasion mining, 2-3 years; and in low-abrasion silt transport, it can exceed 7 years.
Yes, we manufacture with custom flange standards including ANSI, DIN, JIS, GB, and customer-specific designs, with options for carbon steel, stainless steel, and coated flanges for corrosion resistance.
Our Dredge Pipeline features flanged connections requiring only standard tools for assembly. We provide detailed installation manuals and on-site technical support, plus maintenance training for optimal performance.
