China HDPE parts factory introduces the performance characteristics of PE pipes:
1. Reliable connection
The polyethylene pipe system is connected by electric hot melting, and the strength of the joint is higher than the strength of the pipe itself. Polyethylene pipes and other pipes using flange connection are convenient and quick.
2. Excellent impact resistance at low temperature
The low temperature embrittlement temperature of polyethylene is extremely low, and it can be used safely within the temperature range of -60℃ to 60℃. During construction in winter, the pipe will not be brittle due to the excellent impact resistance of the material.
3. Excellent resistance to stress cracking
pe pipes have low notch sensitivity, superior shear strength and excellent scratch resistance, as well as outstanding environmental stress cracking resistance.
4. Excellent chemical resistance
PE pipe can resist corrosion of various chemical media, the chemical substances in the soil will not cause any degradation of the pipe.
5. Aging resistance, long service life
Polyethylene pipes containing 2-2.5% uniform carbon black can be stored or used outdoors for 50 years without exposure to UV radiation.
6. Good wear resistance
The comparison test of wear resistance between PE pipe and steel pipe shows that the wear resistance of PE pipe is 4 times that of steel pipe. In the field of mud transportation, compared with steel pipe, PE pipe has better wear resistance, which means that PE pipe has longer service life and better economy.
7. Great winding ability
The flexibility of PE pipe makes it easy to bend. In engineering, obstacles can be bypassed by changing the direction of the pipe. In numerous cases, the flexibility of the pipe can reduce the amount of pipe fittings and reduce the installation cost.
8. Low flow resistance
The PE pipeline has a smooth inner surface. Its Manning coefficient is 0.009. Smooth surface and non-adhesion characteristics ensure that the pipeline has a higher conveying capacity than traditional pipe, but also reduces the pipeline pressure loss and water transmission energy consumption.
9. Easy handling
PE pipe is lighter than concrete pipe, galvanized pipe and steel pipe. It is easy to handle and install, lower manpower and equipment requirements, means that the installation cost of the project is considerably reduced.
10. Construction methods of a variety of good
PE pipeline has a variety of construction technologies. In addition to the traditional excavation method, a variety of modern trenchless technologies such as pipe jacking, directional drilling, liner and split pipe can be used for construction. This is the only choice for some places where excavation is not allowed, therefore the PE pipeline has a wider application field.
Scope of application of PE water supply pipe:
PE water supply pipe is widely used in municipal water supply, building water supply, old pipeline repair, industry and water treatment and other fields.
