Anti Twist Dredging Pipeline Hose
,Pressure Resistance Dredging Pipeline System
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%.
