Performance characteristics

1. Strong corrosion resistance and long service life. Pipe materials have strong corrosion resistance, with a service life 4-6 times that of steel pipes, and overcome the phenomenon of thin pipe walls and shortened service life caused by corrosion and wear of steel pipes.
2. High security performance. Both the inner and outer layers are made of anti-static and flame-retardant modified polyethylene, and their anti-static and flame-retardant properties can meet the AQ1071-2009MT181-88 standard and on-site requirements.
3. Good impact resistance and flexibility
4. Smooth pipe wall with low resistance.
5. The connection method is secure and reliable
6. Lightweight, easy to transport and construct.
7. Green and environmentally friendly. The raw material is PE resin. Clean, non-toxic, does not produce secondary pollution, and can be reused
