Polyethylene conduit

Our produced pipe materials are coal mine polyethylene pipes (KM), commonly referred to as pipes, which are used for underground water supply and drainage in coal mines, slurry spraying, positive pressure ventilation, negative pressure ventilation, and gas drainage. The reference working temperature for the pipes is 20°C, with an operating temperature range of -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 purposes must have a nominal pressure of not less than 1.0MPa.
