1. Long service life
Polyethylene pipe molecules have good stability and anti-aging properties. Under normal working temperature and pressure conditions, the service life of polyethylene pipes can be guaranteed for more than 50 years.
2. Corrosion resistance
Polyethylene molecular structure stability is very high, resistant to natural gas, liquefied gas, artificial gas and other chemical corrosion, no need for secondary anti-corrosion equipment. The chemical substances in the soil will not degrade the pipe.
3. Good flexibility polyethylene pipe is a kind of high toughness pipe, its elongation at break is more than 500%. The flexibility of polyethylene pipe makes it easy to bend. In engineering, it can bypass obstacles by changing the direction of the pipe. In many cases, the flexibility of the pipe can reduce the amount of pipe fittings and installation costs.
4. It has excellent shock resistance and earthquake resistance
The low temperature embrittlement temperature of polyethylene is very low, and it can be used safely in the temperature range of - 60 ℃ ~ 60 ℃. It has strong adaptability to the uneven settlement of pipe foundation. In winter construction, because of the good impact resistance of the material, there will be no brittle cracking of the pipe.
5. Good wear resistance
The test shows that the wear resistance of PE pipe is 4 times of that of steel pipe, especially in the field of mud transportation, PE pipe has better wear resistance than steel pipe.
6. The flow resistance is small, and the polyethylene pipe has smooth inner surface, and its Manning coefficient is 0.009. The smooth inner surface and non adhesion characteristics ensure that the polyethylene pipe has a higher conveying capacity than the traditional pipe, while reducing the pressure loss and water transmission energy consumption of the pipeline.
7. Good environmental performance
Polyethylene pipe is a kind of green and environment-friendly pipeline material without adding heavy metal stabilizer in the process of processing, and the polyethylene material itself can be recycled and will not pollute the environment.
8. Good flame retardant, antistatic performance, our company specially developed flame retardant, antistatic polyethylene pipe, suitable for flammable and explosive and other specific places.
9. Safe and reliable connection method
Polyethylene pipes are mainly connected by hot-melt or electrofusion, which essentially keeps the identity of interface material, structure and pipe body, realizes the integration of joint and pipe, effectively resists circumferential stress and axial tension stress caused by internal pressure, and has no worry of water leakage and air leakage.
10. Light weight, easy to handle and easy to construct
The specific gravity of polyethylene pipe is only 1 / 8 of that of steel pipe. It is easy to handle and bend. The welding process is simple and rapid, and the comprehensive engineering cost is low. It has remarkable economic benefits
