Pipe Float Is Composed of Steel Float Pipe for Dredging Pipes¹

Product DescriptionPipe Float (Float for Dredging Pipes)Structure and MaterialsA Pipe Float is composed of steel pipe, flotation jacket, outer cover and retaining rings at both ends. The main function of the Pipe Float is to be installed onto a steel pipe to provide buoyancy for it so that it can float on the water. Its main materials are Q235, PE foam and natural rubber.SpecificationApplicationsThe Pipe Float needs to be fixed in the middle of the steel pipe (main mud conveying pipe) after being installed onto it,so that the buoyancy of the combination can remain uniform and balanced. When the steel pipe is worn and broken,the damaged steel pipe can be cut and removed, so the remaining Pipe Floating can be installed onto a new steel pipe and continue to be used.The Pipe Float has good stability. Compared with PE Float, The Pipe Float has better impact resistance and aging resistance, its service life is much longer, and its cost is also higher.As for the design of the reserve buoyancy of the Pipe Float, the layout of the whole pipeline needs to be considered. Ifthe combination of "Pipe Float + Main Conveying Steel Pipe + Buoyancy-free Hose" is used as the basic unit, there serve buoyancy of the whole basic unit under normal working condition should be considered when determine the reserve buoyancy of the Pipe Float.Features(1) With good rigidity.(2) Straight pipe, easy to install.(3) With good floating performance and can provide high reserve buoyancy.(4) With excellent weather resistance.(5) With good resistance to winds and waves.(6) High utilization, replaceable and reusable.Technical Parameters(Custom configurations available upon request.)(1) Bore Size of Supporting Steel Pipe500mm ~ 1000mm(2) Length of Supporting Steel Pipe6m~12m(3) Pipe Float LengthSlightly shorter than the length of supporting steel pipe(4) BuoyancyDepends on the weight of the supporting steel pipe and the specific gravity of the material converyed.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.
