Anti Scour Heavy Duty Dredge Pipeline For High Concentration Slurry

As a leading manufacturer in the marine and dredging industry, Hongruntong Marine is dedicated to providing high-quality dredge hoses that combine performance, durability, and versatility. Our dredge hoses are engineered with advanced EPDM rubber inner layers and steel wire spiral reinforcement, making them highly resistant to corrosion, seawater erosion, and extreme temperature changes.

This makes them ideal for offshore dredging, coastal reclamation, and marine engineering projects, where harsh environmental conditions demand reliable and long-lasting equipment. Each hose undergoes rigorous pressure and sealing tests to ensure compliance with international industry standards, guaranteeing safe and stable operation.

Our dredge hoses feature a user-friendly design, with easy-to-install flange connections that save time and labor during installation and replacement. We focus on customer needs, offering customized solutions for different dredging scenarios, including floating dredge hoses for deep-water operations and submerged hoses for silt transportation.

With a professional R&D team and modern production facilities, Hongruntong Marine ensures consistent product quality, while our global sales network provides timely delivery and comprehensive after-sales support, making us a trusted partner for dredging companies worldwide.

• Ultra-High Wear Resistance: The inner layer is made of proprietary ultra-wear-resistant synthetic rubber compound, achieving 4 times the wear resistance of standard rubber pipelines. Thickened inner layer (14-18mm) withstands long-term scouring by high-concentration slurry, extending service life to 12-18 months.
• Superior Anti-Seawater & Anti-Aging Performance: EPDM rubber outer layer with anti-corrosion and anti-UV additives provides excellent resistance to saltwater corrosion, UV radiation, and harsh marine weather. Special vulcanization process prevents seawater penetration and internal corrosion.
• High Pressure-Bearing Capacity & Structural Stability: Reinforced with 4-6 layers of high-tensile steel wire winding and 2 layers of high-strength cord fabric. Pressure-bearing capacity ranges from 0.8MPa to 2.5MPa. Smooth inner surface reduces flow resistance and improves conveying efficiency.
• Easy Installation & Flexibility: Lightweight and flexible design with precision-machined flange connections or quick-connect joints. Reduces installation time by 30% compared to traditional pipelines. Can be bent at angles up to 30 degrees without affecting performance.

• Offshore Dredging Projects: Designed for deep-sea sand extraction, slurry conveying, and seabed dredging. Compatible with trailing suction hopper dredgers, cutter suction dredgers, and bucket dredgers in harsh offshore environments.
• Coastal Land Reclamation: Used to convey sand, slurry, and fill materials from offshore areas to reclamation sites. High pressure-bearing capacity and large flow rate enable efficient conveying of high-concentration slurry.
• Port & Harbor Dredging: Removes sediment, sand, and debris from berths, channels, and port basins. Flexible structure and easy installation make it suitable for narrow port areas.

• 30+ Years of Professional Manufacturing Experience: Senior engineering team with deep understanding of technical requirements and challenges. Supplied to over 50 countries with 1,000+ successful projects.
• Customized Design Capabilities: Fully customized solutions including working pressure, diameter, length, conveying medium, and working environment. Minimum lead time of 30 days for standard customized products.
• Strict Quality Control & International Certification: Comprehensive quality control system with premium raw materials. CE, ISO 9001, ISO 14001, and ISO 28017 certifications. Third-party testing with SGS and BV.
• Comprehensive After-Sales Service & Technical Support: 24/7 customer support with on-site installation guidance and operation training. Standard 12-month product warranty with spare parts inventory.

Our dredge pipeline is available in customizable diameters ranging from 300mm to 1200mm, and working pressures from 0.8MPa to 2.5MPa. We can also customize larger diameters (up to 1500mm) and higher working pressures (up to 3.0MPa) based on your specific project requirements.

Under normal working conditions (conveying high-concentration sand slurry, offshore environment), our dredge pipeline has a service life of 12-18 months, which is 3-4 times longer than the industry average (3-6 months). The service life can be extended to 24 months if used in less harsh conditions.

Yes, our dredge pipeline is designed with a flexible structure and reliable connection joints, making it suitable for ship-to-ship slurry transfer. We can customize the pipeline with floating buoyancy modules to ensure stable floating on the water surface.

Yes, we provide comprehensive installation guidance and technical training for all customers. Our professional technical engineers will be sent to your site to guide the installation process and provide training on operation, daily maintenance, and emergency handling procedures.

Our dredge pipelines have obtained international certifications including CE, ISO 9001:2015, ISO 14001:2015, and ISO 28017. We also provide third-party test reports from SGS, BV, or DNV to meet project acceptance requirements.
