Our produced pipe materials are coal mine polyethylene pipes (KM), commonly referred to as pipes, which are used for water supply and drainage, slurry spraying, positive pressure ventilation, negative pressure ventilation, and gas extraction in coal mines. 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. For pipes used in gas extraction, the nominal pressure must not be less than 1.0MPa.
