HDPE Dredging Pipe
Key Features of HDPE Dredging Pipe
Light Weight: HDPE dredging pipes are only one-eighth the weight of steel pipes, making them easier and more efficient to transport, install, and dismantle. They are connected using flanges and bolts, which facilitates easy maintenance and replacement.
Great Flexibility and Tensile Strength: These pipes do not break under internal or external force impact and have excellent resistance to stormy waves. They can be bent into circles comprising 4-8 pieces in water and can be connected directly on land as long as the angle does not exceed 30 degrees.
Excellent Wear-Resistance: The wear-resistance of HDPE dredging pipes is 4-8 times greater than that of steel pipes. Combined with their anti-UV and anti-aging properties, they can typically be used for 5-8 years, depending on sand content.
Easy Installation and High Efficiency: The pipes are assembled with metal flanges at both ends and connected by bolts and flanges, ensuring they do not deform or leak during installation and disassembly, thus maintaining high engineering efficiency.
Smooth Inner and Outer Walls: These pipes have smooth walls and a tiny friction coefficient, which increases their transmission efficiency by 20-30% compared to steel pipes.
Wide Workable Temperature Range: HDPE dredging pipes can operate in temperatures ranging from -40°C to 60°C, allowing them to adapt to harsh weather and fluctuating temperatures.
Cost Efficiency: Whether used on land or in water, HDPE dredging pipes offer a lower total engineering cost and higher efficiency compared to other types of pipes.
Applications: These pipes are used in various fields such as delivering powder and coal ash in thermal power plants, transporting mine tailings and slurry in the mining industry, and in dredging projects or sand suction projects for delivering sand, mud, and slurry.
Applications of Dredging Hdpe Pipe
Delivering Powder and Coal Ash in Thermal Power Plants: HDPE dredging pipes are used to transport powder and coal ash effectively in thermal power plants.
Transporting Mine Tailings and Slurry in the Mining Industry: These pipes are suitable for delivering mine tailings and slurry in metallurgical mines and the broader mining industry.
Coal Industry: They are used in coal preparation plants for delivering pulverized coal and coal-water slurry.
Chemical Industry: HDPE dredging pipes are employed to transport mud, slag, and other corrosive media.
Oil and Petroleum Transportation: These pipes are also used for delivering crude oil and petroleum.
Dredging Projects or Sand Suction Projects: In dredging or sand suction projects, HDPE pipes are used for delivering sand, mud, slurry, and are also applicable in seawater treatment projects.
