1. Bendable randomly, able to avoid the obstacle, construction optimization.
2. It can shorten the construction time greatly because each pipe is longer and has fewer joints.
3. The raw material is polyethylene plastic, so it is light and easy for transportation and construction.
4. Because it is in spiral shape, the rigidity is enhanced and is difficult to be deformed after the embedment.
5. Strong tolerance to medicine, strong corrosion resistance.
6. Anti-vibration, anti-ground subsidence , good plasticity, strong pressure resistance.
7. Low friction coefficient, it has iron wire inside, so it is easy to put in the electric wire and the electric cable.
8. To use this tube does not only enhance the construction efficiency, but reduces the construction cost greatly, and after the embedment it also maintains permanent safety performance.
