1. Reliable connection: The polyethylene piping system is connected by electrofusion, the strength of the joint is higher than that of the pipe body: The flange connection between polyethylene pipe and other pipes is convenient and quick.
2. Low temperature impact resistance, polyethylene low-temperature embrittlement temperature is very low, can be safely used in -60-40℃. In winter construction, because the material impact resistance is good, will not occur tube brittle crack.
3. Good cracking resistance: PE has low notch sensitivity, high shear strength and excellent scratch resistance, and the environmental stress cracking performance is very prominent.
4. Good chemical corrosion Resistance: PE pipeline can withstand a variety of chemical media corrosion. Chemicals present in the soil do not cause any degradation of piping materials. Polyethylene is an insulator of electricity, so it does not decay, rust or electrochemical corrosion, and it does not grow in algae, bacteria or fungi.
5. Long service life: the uniform distribution of carbon black polyethylene pipe containing $number can be stored outdoors or used for 50 years, and will not suffer from ultraviolet radiation damage.
6. Good wear Resistance: PE pipe and steel pipe wear resistance comparison test shows that PE pipe wear resistance of 4 times times. such as in the field of slurry transport, compared with the steel pipe, PE pipeline has better wear resistance, which means that the PE pipe has a longer service life and better economic performance.
7. Good flexibility: The flexible use of PE pipe it is easy to bend, engineering can be changed by bending the pipeline way around obstacles, in many cases, the flexibility of the pipeline can reduce the amount of pipe fittings and reduce installation costs.
8. Small flow resistance: PE pipe with a smooth inner surface, the manning coefficient of 0.009 smooth surface and non adhesion characteristics to ensure that the PE pipeline has more than the traditional pipe conveying capacity, but also reduce the pipeline pressure loss and water consumption.
9. Easy to handle: PE pipe lighter than concrete pipe, galvanized pipe and steel pipe, it is easy to carry and install, lower manpower and equipment requirement means lower engineering installation cost.
10. A variety of construction methods: PE pipe with a variety of construction technology, in addition to the traditional excavation methods can be used in the construction, can be used in a variety of trenchless technology such as directional drilling, liner, crack, pipe jacking, etc., which is not allowed to dig the site, is the only choice, so PE pipeline application field is more extensive.
11. Good economy: PE pipe and ball ink tube price, considering the long life of PE pipe, good hydraulic performance and convenient construction, the comprehensive cost is lower
