1. The advantages of PEX pipes are good pressure resistance, wide temperature resistance range, from minus 70 degrees to 95 degrees Celsius, and can withstand temperatures of 110 degrees Celsius in a short time. PEX pipe is resistant to acid and alkali corrosion, can be used for the transportation of various chemical substances, and has excellent high temperature resistance and low temperature performance. The inner and outer walls of the tube are smooth, with low resistance and no scaling. Clean and non-polluting, it can save people from citing "yellow water" and "rust water".
2. The PEX pipe uses special pipe fittings, which can be easily and quickly installed without tapping, snapping, and welding. It is easy to bend, soft and rigid, saves pipe fittings, and is light in weight. The length of the pipe is only one tenth of that of galvanized steel pipe. PEX pipe also has good thermal insulation performance and long service life. Under the environment of 70 ℃, the working pressure is less than or equal to 0.8MPa, and the continuous service life is long-term durability according to standards. However, it has the disadvantage that it cannot be thermally fused, which limits its application range in HVAC and water supply.
