HDPE pipes
A good pipe should not only have good economy, but also have a series of advantages such as stable and reliable interface, material impact resistance, crack resistance, aging resistance, corrosion resistance, etc. Compared with traditional pipes, HDPE pipe system has the following one: Series advantages:
(1) Reliable connection: The polyethylene pipe system is connected by electrothermal fusion, the strength of the joint is higher than that of the pipe body, and the flange connection is used between the polyethylene pipe and other pipes, which is convenient and quick.
(2) Good impact resistance at low temperature: The low temperature embrittlement temperature of polyethylene is extremely low, and it can be used safely in the temperature range of -60-60°C. During construction in winter, due to the good impact resistance of the material, the pipe will not be brittle.
(3) Good resistance to stress cracking: HDPE has low notch sensitivity, high shear strength and excellent anti-tracking ability, and its resistance to environmental stress cracking is also very outstanding.
(4) Good chemical corrosion resistance: HDPE pipes are resistant to corrosion by a variety of chemical media, and the chemicals present in the soil will not cause any degradation to the pipes. Polyethylene is an electrical insulator, so it does not rot, rust or electrochemically corrode; it also does not promote algal, bacterial or fungal growth.
