The tailings conveying HDPE pipe is produced with high toughness and high wear resistance grade HDPE special raw materials, specially designed for long-distance conveying of solid-liquid mixtures such as mine tailings slurry, tailings, slurry, etc. It has excellent wear resistance, pressure resistance and impact resistance. It can resist the long-term initialization of high-concentration particles and runs stably and reliably.
The inner wall of the pipe is smooth, the friction resistance is small, there is no scaling, no hanging material, and it is not easy to block, which greatly improves the transportation efficiency and reduces energy consumption. The pipeline is resistant to acid and alkali corrosion, geological settlement, and has good flexibility. It adapts to the complex terrain and vibration conditions of the mine. It adopts hot melt docking connection. The interface strength is high, the sealing is strong, and there is no leakage. The service life is much higher than that of traditional steel pipes.
It is widely used in all kinds of mine tailings pond transportation, long-distance transportation of tailings mortar, underground filling, mud discharge and solid waste transportation systems. It is an ideal special pipeline for mine green production, energy saving and consumption reduction, and safe operation.
Stable basic wear resistance, suitable for low concentration tailings slurry
Using conventional HDPE raw materials, it can meet the transportation needs of fine-grained, low-concentration tailings slurry, resist conventional sediment erosion and wear, and has outstanding cost performance.
High toughness and impact resistance, adaptable to complex mining conditions
The elongation at break is ≥800%, and it has excellent toughness. It can withstand the impact of tailings particles and geological vibrations, and is not prone to brittle breakage in low-temperature environments.
The inner wall is smooth and low-friction, and it is not easy to accumulate and block the pipe.
The inner wall roughness is ≤0.007mm, the tailings slurry has small flow resistance, and fine particles are not easy to hang on the wall and deposit, ensuring smooth transportation.
Excellent corrosion resistance, suitable for tailings water environment
Resistant to corrosion by acids, alkalis, salts, and tailings wastewater, does not rust or scale, and is not corroded by soil and mineral water when buried for a long time.
Good flexibility, adaptable to mine terrain laying
The pipe has good flexibility and can adapt to the undulations of mountains and the layout of pipeline bends, reducing the use of elbows and reducing the cost of pipe fittings.
Hot melt integrated connection, reliable sealing and anti-leakage
Hot melt and electrofusion connections, the interface strength is higher than the pipe body, effectively preventing tailings slurry from leaking and avoiding environmental pollution.
Light weight, convenient construction and installation
The pipe is light in weight and easy to transport and erect. It can be laid without excavation and buried, which greatly shortens the construction period of the mine pipe network.
Strong adaptability to wide temperature range and high environmental tolerance
The long-term use temperature is ‑40℃～60℃, and it can adapt to the temperature difference between day and night in mining areas, and open-air and underground laying environments.
Stable pressure-bearing performance, meeting conventional conveying pressure
It has complete pressure levels and is suitable for tailings low-pressure and normal-pressure transportation systems, with stable long-term hydrostatic performance.
Long service life and low operation and maintenance costs
The design service life of conventional tailings is ≥50 years, no anti-corrosion treatment is required, subsequent maintenance is simple, and the overall cost of use is low.
