HDPE is a good pipeline, not only should have a good economy, but also should have the interface stable and reliable, material impact resistance, crack resistance, anti-aging, corrosion resistance and a series of advantages, compared with the traditional pipe, HDPE piping System has the following series of advantages:
⑴ connection is reliable: The polyethylene piping system is connected by Electrothermal mode, the strength of the joint is higher than that of the pipe body.
⑵ Low temperature impact resistance: Polyethylene low-temperature embrittlement temperature is very low, can be used safely in the 60-60 ℃ temperature range. Winter construction, because the material impact resistance is good, will not happen tube brittle crack.
⑶ resistance to stress cracking good: HDPE has a low notch sensitivity, high shear strength and excellent scratch resistance, environmental stress cracking performance is also very prominent.
⑷ resistance to chemical corrosion good: HDPE pipe can withstand a variety of chemical media corrosion, the presence of chemical substances in the soil will not cause any degradation of the pipeline. Polyethylene is an electrical insulator, so it does not decay, rust or electrochemical corrosion, nor does it promote the growth of algae, bacteria or fungi.
⑸ Anti-Aging, Long service life: containing 2-2.5% of uniform distribution of carbon black polyethylene pipe can be stored outdoors or used for 50 years, will not suffer from ultraviolet radiation damage.
⑹ Good abrasion resistance: HDPE pipe and steel pipe wear resistance test shows that the wear resistance of HDPE pipe is 4 times times of steel pipe. In the field of slurry transportation, compared with steel pipe, HDPE pipe has better wear resistance, which means that HDPE pipe has longer service life and better economy.
