Our manufactured pipe products are coal mine polyethylene pipes (KM, hereinafter referred to as "pipes"), suitable for underground water supply and drainage, cement spraying, positive pressure ventilation, negative pressure ventilation, and gas drainage in coal mines. The reference working temperature for the pipes is 20°C, with operating temperatures ranging from -10°C to +40°C. There is a pressure reduction factor between 20°C and 40°C, and the working pressure is the nominal pressure multiplied by the pressure reduction factor. The pipes for gas drainage purposes must have a nominal pressure of no less than 1.0MPa.
