Dredge hoses consist of an abrasion-resistant synthetic rubber inner tube, a high-tensile cord and spiral steel wire reinforcement, and a weather-resistant outer cover.
They are classified into three types: floating, suction and discharge dredge hoses.
Product parameters
The floating dredge hose is a self-floating rubber hose particularly designed for the discharge side of a dredger, floating on seawater under its own buoyancy.
Figure 1 — Floating Dredge Hose (self-buoyant, PEF-filled, red flanges).
Construction
Inner tube: high-quality, wear and abrasion resistant rubber.
Reinforcement layer: several layers of high-tensile cord threads and embedded spiral wire.
Filling layer: a dedicated layer for the floating type, filled with PEF (polyethylene foam) to keep the hose floating on water.
Outer cover: high-quality SBR and other synthetic rubber compounds.
Product Features
Features
Self-floating performance on seawater.
Synthetic rubber highly resistant to weathering, UV, salt water and ozone.
Smooth SBR inner tube for wear resistance and non-plugging performance.
Small bending radius: working bending angle 0° to 45°.
Working temperature: -25°C to +80°C. Safety factor 4:1.
Application
Connected to other floating dredge hoses by rubber or steel flanges. Widely used for the discharge of seawater, silt, sand and other dredged materials at ports and docks.

Note: floating dredge hoses with 900 mm and 1200 mm inner diameter can be customized.
Scope of application
Used in waterway clean-ups, dredging, sand pumping, land reclamation, port expansion and other mud or mortar conveying operations.

Similar to other hose products, reinforced / armored floating hoses are preferred for certain projects depending on project requirements. Different types of flanges and/or collars are available, too.
