1, connection reliability: the use of electric heating welding method between the polyethylene pipe system, the strength of the joints is higher than the pipe body strength.
2, low temperature impact resistance good: low temperature embrittlement of polyethylene, can be used in the temperature range of -60-60. Winter construction, due to the impact of the material is good, will not occur the pipe brittle crack.
3, anti stress cracking good: HDPE has a low notch sensitivity, high shear strength and excellent anti scratch ability, resistance to environmental stress cracking performance is also very prominent.
4, resistance to chemical corrosion is good: HDPE pipe can withstand a variety of chemical medium corrosion, soil in the presence of chemicals are not likely to the pipeline caused by any degradation. Polyethylene is an electrical insulator, so it will not decay, rust or corrosion, and it will not promote the growth of algae, bacteria, or fungi.
5, aging resistance, long service life: the uniform distribution of carbon black in the 2-2.5% can be stored in the open air or used for 50 years, will not suffer from UV radiation damage.
6, good abrasion resistance: HDPE pipe and steel pipe wear resistance test shows that the wear resistance of HDPE pipeline is 4 times. In the mud conveying field, the HDPE pipe has better wear resistance than that of the steel pipe, which means that the HDPE pipeline has longer service life and better economic performance.
7, good flexibility: the HDPE pipe flexibility makes it easy to bend, engineering can by changing the pipeline to bypass obstacles, on many occasions, the pipeline flexible can reduce the amount of pipe fittings and reduce the cost of installation.
