Description

Hongruntong Marine’s Self-Floating Hose is a purpose-built flotation hose that combines reliable buoyancy with abrasion-resistant conveyance for cutter-suction and trailing-suction dredging. The hose features an integrated closed-cell foam buoyancy layer that maintains positive flotation and stable handling in varying sea states, reducing the need for external floats and simplifying deployment.

Constructed from multi-layer synthetic rubber with fabric and/or steel-wire reinforcement, the design balances flexibility, wear resistance and burst strength for continuous slurry transfer. The abrasion-resistant inner liner and durable outer cover protect against sand, silt and UV exposure, while the foam-filled core preserves shape and prevents water ingress even under prolonged service conditions.

All hoses are available in customizable diameters, lengths and end fittings to suit specific dredger interfaces and project requirements. Each unit is factory-tested for buoyancy, pressure/flow integrity and dimensional accuracy to ensure predictable field performance, reduced maintenance and minimal downtime.

Ideal for dredging, land reclamation, barge transfer and beach nourishment operations, Hongruntong Marine’s Dredge Self-Floating Hoses are backed by OEM manufacturing, technical support and bespoke fabrication to meet project specifications. Contact us for datasheets, sizing advice and quotation.

The Structures of Self-Floatig Hoses

Hongruntong Marine’s Dredge Self-Floating Hose features an integrated, multi-layer construction designed for superior buoyancy and durability in dredging operations. The inner rubber liner is highly abrasion-resistant to handle sand, slurry and gravel. Reinforced with high-tensile synthetic fabric or steel wire, it provides excellent pressure resistance and flexibility. The outer layer consists of high-strength Closed-Cell Foam that ensures permanent buoyancy and prevents water absorption, all encased by a UV- and weather-resistant rubber cover for long-term marine performance. Flanged ends or customized connectors are available to match different dredger systems.

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

● Reinforcement: Multiple layers of high-strength High Tensile Synthetic Textile Cord.

● Float: High-Density Closed Cell Foam.

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

Applications

● Cutter-suction and trailing-suction dredger discharge lines

● Land reclamation and beach nourishment projects

● Offshore dredging and slurry transfer pipelines

● Barge and shore material delivery systems

● Floating pipelines for sand or silt transportation

How Does The Self-Floating Hose Work?

The Dredge Self-Floating Hose connects between the dredger and discharge pipeline, carrying dredged slurry or sand while maintaining buoyancy on the water surface. The closed-cell foam layer provides constant flotation without additional hose floats, keeping the line stable even under heavy flow or wave impact. Its flexible structure allows easy handling, reduces stress on dredging equipment, and maintains consistent flow during operation, ensuring safe and efficient dredging performance.

● Integrated Design — Hose and float combined into one efficient, self-floating system.

● Durable Construction — Multi-layer rubber and foam structure built for long service life.

● Excellent Buoyancy — Closed-cell foam prevents water absorption and maintains stability.

● Custom Engineering — Available in various diameters, lengths and end connections.

● Proven Quality — 100% factory-tested for buoyancy, pressure integrity and durability.

● Reliable OEM Supplier — Over 30 years of marine and dredging experience with global clients.
