HDPE is a good pipeline. It should not only have good economic efficiency, but also have a series of advantages such as stable and reliable interface, anti-impact, anti-cracking, anti-aging, and corrosion resistance. Compared with traditional pipes, HDPE piping system has The following series of advantages:
⑴Reliable connection: The polyethylene pipe system is connected by electric heat melting, and the strength of the joint is higher than the strength of the pipe body.
⑵Good low-temperature impact resistance: The low-temperature embrittlement temperature of polyethylene is extremely low, and it can be used safely in the temperature range of -60-60℃. During construction in winter, because the material has good impact resistance, the pipe will not be brittle.
⑶ Good stress cracking resistance: HDPE has low notch sensitivity, high shear strength and excellent scratch resistance, as well as outstanding environmental stress cracking resistance.
⑷Good chemical corrosion resistance: HDPE pipelines can withstand the corrosion of a variety of chemical media, and the chemical substances in the soil will not cause any degradation to the pipeline. Polyethylene is an electrical insulator, so it will not rot, rust or electrochemical corrosion; in addition, it will not promote the growth of algae, bacteria or fungi.
⑸Aging resistance and long service life: The polyethylene pipe containing 2-2.5% evenly distributed carbon black can be stored or used outdoors for 50 years without being damaged by ultraviolet radiation.
