Performance
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 and corrosion resistance. Compared with traditional pipe, HDPE pipe system has the following one. Series advantages:
(1) Reliable connection: The polyethylene pipe system is connected by electric hot melt method, and the strength of the joint is higher than the strength of the pipe body.
(2) Good low temperature impact resistance: The low temperature embrittlement temperature of polyethylene is extremely low, and it can be safely used in the temperature range of -60-60 °C. In winter construction, due to the good impact resistance of the material, the tube will not be brittle.
(3) Good resistance to stress cracking: HDPE has low notch sensitivity, high shear strength and excellent scratch resistance, and environmental stress cracking resistance is also outstanding.
(4) Good chemical resistance: HDPE pipelines can withstand the corrosion of a variety of chemical media, and the chemicals present in the soil will not cause any degradation to the pipeline. Polyethylene is an electrical insulator and therefore does not rot, rust or electrochemically corrode; it also does not promote the growth of algae, bacteria or fungi.
