Our produced pipe materials are coal mine polyethylene pipes (KM, hereinafter referred to as pipes), which are used for water supply and drainage, spraying, positive pressure ventilation, negative pressure ventilation, and gas extraction in coal mine shafts. The reference working temperature for the pipes is 20°C, with a working temperature range of -10°C to +40°C. There is a pressure reduction coefficient between 20°C and 40°C, and the working pressure is the nominal pressure multiplied by the pressure reduction coefficient. For pipes used in gas extraction, the nominal pressure must not be less than 1.0MPa.
