3 Inch Suction Hose Easy To Install And Maintain High Grade Nr
Rubber Lining
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.
