Product Details
Large Diameter Dredge Hose
,Steel Flange Dredge Hose
,High Abrasion Resistance Dredging Hose
Dredge Hose is a reinforced industrial hose engineered for the transportation of abrasive slurry, sand, silt, mud, sediment, and water-solid mixtures in dredging and marine construction systems. It is commonly installed between dredging pumps, dredgers, floating pipelines, booster stations, discharge pipelines, and shore-based material receiving facilities.
Hongruntong Marine Dredge Hose can be manufactured using an abrasion-resistant rubber inner lining, high-strength textile reinforcement, optional steel wire reinforcement, and a protective outer rubber cover. The hose can be supplied in different nominal internal diameters, overall lengths, wall constructions, and end-connection configurations to meet specific project requirements.
A river navigation channel improvement project in Central Europe required the removal of accumulated sand and sediment from sections of a commercial waterway. The project involved a cutter suction dredger with an operating displacement of approximately 3,500 tonnes, supported by a floating discharge pipeline and temporary shore-based sediment receiving area.
The main operational challenge was the changing composition of dredged material, ranging from fine sediment to compacted sand and localized coarse particles. This variation created different abrasion conditions along the pipeline, requiring careful hose selection and monitoring of flow stability and internal wear.
The project team evaluated reinforced Dredge Hose configurations for slurry transfer points, considering nominal bore, expected flow rate, pump discharge pressure, material characteristics, connection dimensions, and permitted bending radius. The installation emphasized planned inspection, correct hose selection, and replacement based on condition and approved service limits.

The inner lining is the primary wear-contact surface designed to resist erosion caused by repeated contact with suspended solid particles. The lining specification reflects the nature of the conveyed material, with thickness and compound determined according to the intended application rather than general-purpose reference.
The reinforced body provides structural support and enables operation within specified pressure limits. Reinforcement incorporates high-strength textile layers, synthetic cords, or other materials configured to withstand intended operating conditions when correctly selected and installed.
Provides flexibility where conveying systems must accommodate differences in alignment or changes in equipment position. The degree of flexibility depends on hose diameter, wall construction, reinforcement, temperature, and specified minimum bending radius.
The outer cover provides a protective barrier against sunlight, rain, moisture, mud, sediment, and contact with surrounding structures. Cover specification considers intended operating temperature, weather exposure, contact surfaces, and handling requirements.

The working pressure should be based on the pumping system, pipeline resistance, operating conditions, and any expected pressure fluctuations. The selected hose must have a documented working pressure suitable for the intended duty.
The lining should be selected according to the conveyed material and wear conditions. Particle size, hardness, concentration, flow velocity, and operating duration should be considered when establishing the required lining specification.
A Dredge Hose may be used as part of a floating dredging system if its construction, pressure rating, connections, and installation arrangement are suitable. However, standard hoses do not automatically provide buoyancy.
Maintenance should include regular inspection of the hose body, outer cover, coupling areas, and connection points. Inspection frequency should reflect operating severity and manufacturer's guidance.
Customized dimensions and connection configurations may be available depending on requested specification and manufacturing feasibility. Customers should provide required diameter, length, working pressure, and installation conditions.
