Mine Sealing Pipe

Our produced pipe materials are coal mine polyethylene pipes (KM, hereinafter referred to as pipes), which are used for water supply and drainage, slurry spraying, positive pressure ventilation, negative pressure ventilation, and gas drainage in coal mine shafts. 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 used for gas drainage must have a nominal pressure of no less than 1.0MPa.
