Product DescriptionSpecial HosesIn addition to regular dredging hoses, CDSR also produces and supplies special hoses such as Pre-shaped Elbow Hose, jetWater Hose, etc. for specific applications. CDSR is also in the position to supply dredging hoses with customized design.SpecificationJet Water HoseTheJet Water Hose is designed to convey water, seawater or mixed water containing a small amount of sediment under certainpressure. Generally, the Jet Water Hose doesn't wear much but is usually under high pressure during use. Therefore it requiresrelatively high pressure rating, high flexibility and extensibility and sufficient stiffness.Jet Water Hoses are often applied on Trailing Suction Hopper Dredgers, installed at the draghead, in the flushing pipeline on thedrag arm and in other flushing system pipelines. They can also be applied in long-distance water conveying pipelines.Types:Jet Water Hose with Steel Nipple, Jet Water Hose with Sandwich FlangeFeatures(1) Easy to install.(2) Weather resistant, with excellent bending resistance and flexibility.(3) Suitable for high pressure conditions.Technical Parameters(Custom configurations available upon request.)(1) Bore Size100mm, 150mm, 200mm, 250mm, 300mm, 350mm, 400mm, 450mm(tolerance: ±3 mm)(2) Hose Length10 m ~ 11.8 m(3) Working Pressure2.5 MPa* Customized specifications are also available.IllustrationDredging HoseThis detailed image illustrates the precise deployment locations of various specialized dredging hoses within a comprehensive marine operation. It maps the entire sediment transport route, starting with the Sinking Hose resting on the seabed for initial material intake, often near a cutter. Jet Water Hoses are strategically positioned to fluidize compacted sediments near the suction point. The critical transport path is formed by connected Section Hoses, comprising the main pipeline. Buoyancy is managed using Floats supporting sections requiring surface positioning. Tapered Floating Hoses facilitate smooth connections between pipes of differing diameters or at transition points. Where the seabed slopes significantly, Slope Adapted Hoses accommodate these contours without excessive stress. The majority of the surface pipeline often consists of Full Floating Hose sections, kept buoyant along their entire length. Approaching the discharge location, Discharge Hoses handle the final transport of the sediment-water mixture. Finally, Bow Blowing Hoses are specifically deployed for direct connection to barges or vessels, enabling precise sediment placement during discharge operations. The visualization clearly highlights how each hose type – from sinking intake to floating transport to specialized discharge – is optimally positioned to handle depth variations, seabed topography, buoyancy requirements, connection challenges, and the final placement of dredged material, ensuring efficient and effective sediment transfer throughout the system.Drawings & DimensionsDetailed CAD drawings and dimensional diagrams are available for download here or upon inquiry.
