Hongruntong Marine's Dredge Pipeline is a high-performance, heavy-duty composite pipeline system specifically engineered for the rigorous demands of slurry, sediment, and sand transport in large-scale dredging, mining, and coastal infrastructure projects. Crafted with a multi-layered structure that integrates a high-wear resistant synthetic rubber inner liner, high-strength steel cord reinforcement, and a corrosion-resistant outer protective layer, this pipeline delivers exceptional durability, flexibility, and pressure stability for continuous, long-term operation in the harshest marine and industrial environments.
Available in standard diameters ranging from 250mm to 1200mm, with custom lengths up to 12.5 meters, the Dredge Pipeline is optimized to handle high-volume slurry flow with solid concentrations up to 80% by weight, making it ideal for both suction and discharge operations in large cutter suction dredgers, trailing suction hopper dredgers, and land-based slurry pumping systems.
In 2023, a leading global dredging consortium was commissioned to implement a large-scale offshore land reclamation project in Singapore, requiring the transport of 2.8 million cubic meters of sand from offshore borrow sites to the reclamation area. The project presented unique challenges, including strong open-sea currents, high salinity, and the need for continuous, high-volume sand transport over long distances (up to 15km), with minimal maintenance and zero operational downtime.
Hongruntong Marine supplied 1,800 meters of 1000mm diameter floating Dredge Pipeline with a 18-bar working pressure rating, customized with integrated buoyancy modules and corrosion-resistant flanges to withstand the harsh offshore conditions. Over the 8-month project duration, the pipeline operated continuously with zero leaks, joint failures, or structural damage, increasing daily sand transport volume by 38% compared to the consortium's previous pipeline system.
The client praised the pipeline's stable floating performance and low maintenance requirements, which reduced operational costs by 22% and allowed the project to be completed 3 weeks ahead of schedule.

Hongruntong Marine's Dredge Pipeline features a specially formulated synthetic rubber inner liner with a hardness of 70±5 Shore A, engineered to withstand the most abrasive slurry and sediment transport applications. The liner is reinforced with high-strength fiber additives, delivering an abrasion loss of ≤60mm³ per ISO 4649 standards—35% lower than industry averages—ensuring 4x longer service life compared to standard rubber pipelines.
Our floating Dredge Pipeline is integrated with high-density foam buoyancy modules, custom-engineered to provide optimal buoyancy and stability in open-sea conditions. The buoyancy modules are securely bonded to the pipeline's outer layer using a proprietary adhesive, ensuring a water-tight seal that prevents water ingress and buoyancy loss.
The Dredge Pipeline's outer cover is manufactured from a chloroprene-nitrile rubber compound that provides exceptional resistance to saltwater corrosion, industrial chemicals, and harsh environmental conditions. The compound resists hydrolysis, microbial attack, and chemical degradation, ensuring no performance loss even after prolonged exposure to saltwater, mining chemicals, or industrial wastewater.
Engineered with a multi-layer steel cord spiral reinforcement, the Dredge Pipeline delivers exceptional vacuum resistance, making it ideal for heavy-duty suction dredging operations. The pipeline can withstand vacuum levels up to 0.95 bar (95% vacuum), ensuring structural integrity without collapse or deformation during suction operations.
Hongruntong Marine brings over 30 years of specialized experience in designing and manufacturing Dredge Pipeline systems, with a particular focus on floating offshore applications. We have supplied floating Dredge Pipeline to 300+ offshore dredging projects across 50+ countries, earning a reputation for reliability and performance in the most demanding marine environments.
We offer fully customized floating Dredge Pipeline solutions, with buoyancy modules, pipeline diameter, length, and pressure rating tailored to each project's specific requirements—including wave conditions, current speeds, and transport distance.
Hongruntong Marine adheres to the highest quality standards, sourcing only premium raw materials from certified global suppliers. Each batch of Dredge Pipeline undergoes rigorous quality testing to ensure compliance with international standards (ISO 28017, ABS, and DIN 8609).
We provide comprehensive on-site technical support for all Dredge Pipeline projects, including installation guidance, commissioning, operational training, and troubleshooting. Our global service network ensures timely technical assistance wherever your project is located.
