PVC Agricultural Irrigation Pipe

Our produced pipe materials are coal mine polyethylene pipes (KM, hereinafter referred to as pipes), suitable for underground water supply and drainage, concrete spraying, positive pressure ventilation, negative pressure ventilation, and gas drainage in coal mines. 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 for gas drainage, the nominal pressure must not be less than 1.0MPa.
