The dredging pipeline is specially designed for river dredging, port dredging, reservoir dredging, channel dredging and other projects. It is extruded with high-strength and high-toughness polymer materials, which have excellent impact resistance, wear resistance and aging resistance. It can transport mud, silt, sand and gravel, mud mixture and other media for a long time.
The inner wall of the pipe is smooth and smooth, no scaling, no hanging mud, no blockage, effectively reducing the conveying resistance and improving the dredging efficiency. The overall flexibility is good, high pressure resistance, acid and alkali corrosion resistance, hot melt butt or flange connection is adopted, the interface strength is high, the sealing is strong, and there is no leakage. It can adapt to the complex water environment such as rivers, ports, reservoirs and long-term water flow initialization.
It is widely used in river dredging, port dredging, reservoir dredging, channel dredging, lake dredging and other projects. It is an ideal special pipeline for water conservancy dredging, environmental management and channel maintenance.
High wear resistance and erosion resistance, suitable for dredging and conveying mud, sand and rocks
Special dredging grade HDPE raw material, resistant to high-speed erosion and wear of sand and gravel, and long-term slurry impact;
Ultra-high toughness and impact resistance, adaptable to complex working conditions above and below water
Elongation at break ≥800%, resistant to stone impact, wave impact, hoisting collision, and not brittle in low temperature environments;
The inner wall is super smooth, and the transportation is smooth and it is not easy to accumulate and block the pipe.
The inner wall roughness is ≤0.007mm, the water flow resistance is small, the sediment is not easy to adhere and deposit, and the dredging and transportation efficiency is high;
Resistant to seawater and salt spray corrosion, suitable for coastal river dredging
Strong chemical inertness, resistant to corrosion by seawater chlorine ions, salt spray, silt and humus, and stable for long-term underwater use;
Flexible and bendable, adaptable to dynamic deformation of dredging pipelines
It has excellent flexibility and can be deformed with the shaking of the hull, water flow, and river bed settlement, and is not easy to break or break;
Integral hot-melt connection, integrated flange connection of pipes, no leakage in water and underwater sealing
The pipe is integrated with flanged flange root connection, and the interface strength is higher than that of the pipe body, which can resist the impact of high-pressure mud and prevent leakage;
It has light specific gravity and can float, making water construction convenient and efficient.
The density of the pipe is smaller than that of water and can float on the water, making it easy to splice, tow, and lay out on the water, greatly reducing the cost of water construction;
Complete pressure levels to meet high-pressure mud transportation
Pressure-bearing PN0.6–PN2.5MPa, suitable for high-pressure mud transportation by cutter suction and rake suction dredgers;
Anti-aging and weather-resistant, long-term stable outdoors and underwater
Resistant to ultraviolet rays and marine environment aging, suitable for long-term use on open water and underwater burial;
Long service life and low comprehensive operation and maintenance costs
The designed service life in river and ocean dredging conditions is ≥50 years, with no anti-corrosion maintenance and low replacement frequency.
