HDPE mining pipe
product description
HDPE mining pipe is made of high-density polyethylene as the main raw material, adding high-performance superconducting carbon black as antistatic agent, decabromodiphenyl ether and antimony trioxide as flame retardant, fully mixed plasticized and extruded. New environmental protection pipe.
Performance characteristics
★Flame retardant and antistatic: The antistatic component and flame retardant component of the polyethylene pipe used in coal mine are evenly distributed in the pipe body. Therefore, the antistatic and flame retardant performance indexes will not be affected by the long use time. Antistatic and flame retardant performance are in line with national standards, and are suitable for specific places where flammable and explosive underground.
★Light weight and easy installation: The density of polyethylene pipe used in coal mine is small, the unit weight is only 1/8 of steel pipe and 1/3 of glass pipe. Therefore, the polyethylene pipe used in coal mine is not only convenient for transportation and installation, but also can be greatly used when used underground. Reduce the labor intensity of workers and improve work efficiency.
★ Corrosion-resistant and non-fouling: The polyethylene used in coal mines is highly resistant to corrosion and non-fouling. It is especially suitable for water that transports high-sulfur water in underground and transports water containing calcium and magnesium ions. The cost of anti-corrosion and descaling is greatly saved, and the service life is much higher than that of steel pipes, and the comprehensive economic benefits are high.
★ Self-lubricating: The inner wall of the polyethylene pipe used in coal mine is smooth, the resistance is small when conveying fluid, and the roughness is much smaller than that of steel pipe and FRP pipe. Under the same conditions, the conveying capacity can be increased by 30%. Good flexibility and strong resistance to geological sedimentation;
★ Anti-aging and anti-fast cracking performance: Polyethylene pipe for coal mine has good anti-aging performance, is not easy to embrittle at low temperature, and has good resistance to rapid cracking; has good toughness and can effectively absorb impact energy; moderate flexural modulus, fracture extension The long rate is as high as 400% or more. Under the special operation conditions of coal mine underground, geological subsidence and other phenomena, the polyethylene pipe used in coal mine can effectively avoid the fracture accident compared with the traditional hard steel pipe and glass steel pipe.
★ Good wear resistance: The comparison of the wear resistance of polyethylene pipes and steel pipes for coal mines shows that the wear resistance of polyethylene pipes for coal mines is four times that of steel pipes. In the field of coal transportation, compared with steel pipes, polyethylene pipes for coal mines have better wear resistance, which means that polyethylene pipes for coal mines have longer service life and better economy.
★ Impact resistance: Low temperature of polyethylene The embrittlement temperature is extremely low and can be used at lower temperatures.
★Easy connection: It adopts hot melt connection, pipe clamp connection or flange connection, which is convenient for construction. Product performance standards
Implementation of the coal industry standard MT558.1-2005 "Polyline (PE) pipe for underground coal mines" standard
