1. What is the temperature resistance of the ppr tube? The long-term normal working temperature of Ppr pipe is below 70 ℃, ppr pipe is divided into ppr cold water pipe and ppr hot water pipe. The range is -10℃~90℃, and the applicable scope is wider. Ppr pipe can be used in many fields such as household water supply, heating, landscaping, chemical sewage, engineering decoration, compressed air pipeline and so on. 2. Factors affecting the temperature resistance of ppr tubes One factor that affects the temperature resistance of ppr pipe is the raw material of ppr pipe. The raw material is the main factor that limits the performance of a kind of pipe. The better the raw material, the wider the applicable temperature range of ppr pipe; the second: wall thickness, wall thickness also affects ppr pipe A major factor for the applicable temperature, the ppr pipe of the same material, the thicker the wall thickness, the stronger the temperature resistance. Third: the production process, the quality of the production process, can also directly determine the quality of the ppr pipe, so it can also affect the temperature range of the ppr pipe. According to the different pressure of Ppr pipe, the wall thickness of ppr pipe of the same specification is different. The thicker the wall thickness, the greater the pressure.
