Reliable connection: the polyethylene pipe system is connected by electric heating, and the strength of the joint is higher than the strength of the pipe body; the low temperature impact resistance is good: the low temperature embrittlement temperature of polyethylene is extremely low, which can be in the temperature range of -60-60 ℃ Safe to use. During winter construction, due to the good impact resistance of the material, pipe brittle cracking will not occur; good stress cracking resistance: HDPE has low notch sensitivity, high shear strength, excellent scratch resistance, and environmental stress cracking resistance. Also very prominent.
