A reliable connection: polyethylene piping systems electric heating melt connection between joint strength than the pipe body strength.
B good low-temperature impact resistance: low temperature brittleness temperature of polyethylene is extremely low, can be used-60-60 temperature range safety. Winter construction by materials good impact resistance, not pipe rattle.
C good stress cracking resistance: HDPE notch sensitivity with low and high shear strength and excellent scratch resistance, environmental stress cracking resistance is also very prominent.
