Product Description

Floating Steel Pipe (Floating Pipe / Dredging Pipe)

A Floating Steel Pipe is composed of steeflanges at both ends. The main materials or more wear-resistant alloy steel.

Structure and Materials

A Floating Steel Pipe is composed of steel pipe, flotation jacket, outer cover and materials of the steel pipe are Q235, Q345, Q355 or more wear-resistant alloy steel.

Specification

Applications

The Floating Steel Pipe is mainly used in floating pipelines. Due to the characteristi Floating Steel Pipes need to be connected alternately with rubber hoses in a pipelineduring use. The Floating Steel Pipe has good resistance to wind and waves, but meaa pipeline composed of Floating Steel Pipes and rubber hoses, the rubber hoses usand the bending angle of each rubber hose has to be within a reasonable rangepipeline is smooth and unobstructed. Therefore, the pipeline layout is very import pipeline is used in a relatively gentle environment, so as to prevent rubber hoses 
caused by strong winds and big waves, and will lead to the failure of normal operating If the operating has to be carried out in the environment of strong winds and big withstand, a pipeline composed of Floating Steel Pipes spaced connected with Float as a solution in this case. Its cost is higher compared with the Floating Steel Pipes a it is generally not recommended as the first option. The Floating Steel Pipe has high conveying capacity and can transport all kinds of can not only convey mixtures of water(or seawater), silt, clay and sand, ranging in sp g/cm³, but also convey mixtures of water(or seawater), gravel, flaky weathered rock gravity from 1.0 g/cm³ to 2.3 g/cm³.

Features
(1)With good rigidity, straight pipe ensures good smoothness.
(2) With good wear resistance.
(3)Lining with low friction coefficient, low conveying resistance.
(4)Relatively wide range of working pressure rating.
(5)With high tensile strength and stiffness.
(6) With good floating performance, can float on the water under working conditions.
(7)With good working stability and good resistane to winds and waves.

Illustration

Dredging Hose

This 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.
