Description

Hongruntong Marine’s Dredge Suction Hose is a heavy-duty, steel-ring reinforced suction hose engineered to provide reliable vacuum performance and collapse resistance in cutter-suction and trailing-suction dredging. Designed for harsh dredging environments, it combines high abrasion tolerance with flexible handling to ensure continuous suction and reduced operational interruptions.

The hose features a multi-layer synthetic rubber construction with embedded steel rings (or optional steel-wire reinforcement) that maintain internal shape under high vacuum and bending loads. The abrasion-resistant inner liner and robust outer cover protect against wear, UV and weathering, while customizable diameters, lengths and end fittings allow seamless integration with different dredger systems.

All hoses are factory-tested for vacuum integrity, dimensional accuracy and abrasion resistance before shipment, delivering predictable field performance and lower maintenance costs. The steel-ring design improves service life and safety by preventing collapse during high-suction, heavy-solids operations, making it suitable for demanding slurry and sand handling tasks.

Ideal for river/channel maintenance, land reclamation, beach nourishment and sand-mining projects, Hongruntong Marine’s Dredge Suction Hoses are backed by OEM manufacturing capability, technical support and bespoke fabrication to meet project specifications.

The Structures of Suction Hoses

Hongruntong Marine’s Dredge Suction Hose is built with a multi-layer heavy-duty structure designed for high suction efficiency and long service life. The inner rubber liner provides excellent abrasion resistance against sand, gravel and slurry. Reinforced with high-tensile synthetic fabric and embedded steel rings, the hose maintains its shape under strong vacuum pressure and bending forces. The outer rubber cover resists weather, ozone and seawater corrosion. End connections such as steel flanges or customized couplings ensure a secure, leak-free installation on cutter-suction or trailing-suction dredgers.

● Inner Lining: Hongruntong Grade A+++ Natural Rubber.

● Reinforcement: Multiple layers of high-strength High Tensile Synthetic Textile Cord with Steel Wire Helix and Steel Rings.

● Outer Cover: Ozone, weather, UV, and abrasion-resistant neoprene rubber.

Applications

● Cutter-suction dredgers for sand, slurry and silt suction

● Trailing-suction hopper dredgers for offshore dredging operations

● River and port maintenance projects

● Land reclamation and coastal protection

● Sand mining and gravel extraction

● Slurry transfer in industrial and dredging pipelines

How Does The Suction Hose Work?

The dredge suction hose connects the dredge pump to the suction head, transferring material from the seabed or riverbed to the dredger. Under strong negative pressure, the steel-ring reinforcement prevents the hose from collapsing while maintaining flexibility for vessel movement. The abrasion-resistant inner lining ensures smooth suction of high-density slurry, while the hose’s structure absorbs vibrations and pressure fluctuations during continuous dredging operations.
