Plastic pipe is a corrosion-resistant material, which can avoid the risk of pipe leakage and poor water quality caused by steel pipe corrosion. two。 Thermal insulation performance. The thermal conductivity of plastic pipe is lower than that of steel pipe, and the heat loss of plastic pipe is less than that of steel pipe under the same heat preservation and laying conditions. 3. Pipe structure. Plastic pipes generally do not exceed the pressure. 9. Thickness of pipe wall. The plastic pipe will creep and relax at high temperature, and the mechanical strength decreases with time, which is related to the working temperature and time. When designing, it is necessary to calculate the design strength of the pipeline and determine the thickness grade of the pipeline according to the temperature curve and operating life of the system.
