The special water supply pipe for mining is made of high-strength HDPE, which is specially designed for the production of water supply, construction water, dust sprinkler and other scenarios in the mine. It has excellent pressure resistance, impact resistance and aging resistance, and can meet the continuous and stable water supply needs of the mine.

The inner wall of the pipe is smooth, the water flow resistance is small, the water transfer efficiency is high, there is no scaling, no breeding of microorganisms, and the water quality is clean and safe. At the same time, it is resistant to acid and alkali corrosion, groundwater erosion, and adapts to the complex environment of damp, dusty, and frequent vibration underground. It has good flexibility, can adapt to the bending of the roadway and slight geological settlement, and is not easy to break.

Adopting hot-melt butt or flange connection, it has high interface strength, good sealing, no leakage, convenient installation, and low operation and maintenance cost. It is widely used in mining underground production water supply, dust spraying, equipment cooling, construction water and other systems. It is an important supporting pipeline for safe production and civilized construction in mines.

• Steel wire reinforced structure, ultra-high pressure-bearing performance

  The steel mesh skeleton is compositely reinforced and can withstand pressure up to PN1.6-PN10.0MPa, and the high-pressure water supply will not burst the pipe;

• Double protection of inner and outer layers of HDPE, resistant to mineral water corrosion

  The outer layer is anti-aging and wear-resistant, and the inner layer is resistant to corrosive water in mining areas, anti-scaling and anti-penetration;

• Resistant to impact and creep, suitable for underground high-pressure working conditions

  Resist slow crack growth, resist hydraulic pulse impact, and adapt to mine hydraulic pressure fluctuations and geological deformation;

• Antistatic and flame resistant, meeting mining safety regulations

  Can achieve antistatic and flame retardant modification to avoid the risk of underground sparks;

• Steel-plastic combination, both rigidity and toughness

  The strength is higher than that of pure PE pipes, the flexibility is better than that of steel pipes, it can be laid in a bend, and it is resistant to settlement and vibration;

• Reliable high-pressure connection and zero leakage of high-pressure water supply

  Special high-pressure component connections, tight sealing of steel-plastic interface, suitable for long-distance high-pressure water supply underground;

• Lightweight, easy to install, high mining construction efficiency

  The dead weight is much lower than steel pipes, which facilitates underground transportation and docking. 50mm-225mm diameter pipes can be customized according to actual working conditions, greatly shortening the pipe network laying period;

• Long-term stability and durability, reducing mine water supply operation and maintenance costs

  The service life of high-pressure water supply in mining areas is ≥30-50 years, without the need for anti-corrosion and frequent maintenance and replacement.
