Description
Dredge hoses are used in both land reclamation and environmental dredging. Their thick rubber layers and reinforced bodies provide excellent kink resistance and dimensional stability during heavy slurry transfer.
Depending on the dredging system, hoses may come in suction, discharge, or floating types, each tailored to unique operational demands.
( Case: In a lake restoration project in Canada, traditional rigid piping was causing sediment blockages and was difficult to maneuver. Replacing the system with flexible dredge hoses allowed easier routing and adjustment to terrain.
The new hose setup improved operational agility and significantly reduced clogging incidents. Project managers reported faster progress and lower maintenance efforts, improving both ecological and economic outcomes. )

Features
Low Maintenance Requirements
Durable construction and quality materials reduce the need for frequent inspection or replacement.
High Flow Capacity
Smooth bore design reduces friction loss and maintains efficient slurry flow rates over long distances.
Temperature Tolerant
Capable of operating reliably in extreme cold or heat conditions (-30°C to +80°C or higher, depending on design).
Modular Design for Easy Transport
Hoses can be disassembled and reassembled quickly, ideal for mobile or temporary dredging operations.
Applications
Cutter Suction Dredger Applications
Installed as flexible pipeline components to connect the dredger cutter head to the onboard pump system or to shore pipelines.
Trailing Suction Hopper Dredger Operations
Suction hoses are used to transfer seabed materials into the vessel’s hopper. Hoses must resist vacuum pressure and abrasion during continuous loading.
Floating Pipeline Systems
Used in floating dredging pipelines that require hoses to remain buoyant, flexible, and resistant to wave impact and UV exposure.
Advantages
International Standards Compliance
Products comply with ISO, BV, CCS, and other relevant international marine and industrial certifications.
Strong Production Capacity
Large-scale manufacturing capabilities support bulk orders and continuous supply.
Reliable After-Sales Support
Dedicated service team for technical guidance, installation consulting, and warranty follow-up.
Integrated Flange & Coupling Solutions
We provide full assembly of hoses with custom flanges, nipples, and steel components.
