Features of the HDPE Hollow Wall Spiral Pipe:

1. Chemical resistance: Cannot be eroded by sewage, waste water and chemicals, cannot be eroded by the putrefaction in soil.

2. Impact resistance:Because the use of I type wall structure, the pipe has high compression resistance and impact resistance, which will not be broken by the settlement of the groundwork, and it can easily resume original shape after deformation. The pipe has perfect applicability to any groundwork.

3. Aging resistance: The pipe is always in black color, it can endure the strong sunlight during storage and construction.

4. Frozen resistance: The pipe cannot be frozen to break or bulge to leakage even when the temperature is at -80℃.

5. Light weight: Easy in transportation and construction. Its only 1/8 in weight compare with cement pipe. Only rooter is needed to place the pipe. No need any heavy equipment.

6. Easy to connect: The pipe can be connected outside the channel and then move into channel with crane. When in municipal drainage project more time and costs can be saved.

7. Abrasion resistance: The pipe has higher abrasion resistance than steel pipe and cement pipe. It has perfect flow capacity for household sewage and waste residue. With smooth inner wall the pipe has perfect drainage capacity, low friction and fast drainage.

8. Economy efficiency: Low raw material costs, low construction, supervision and maintenance costs.

9. Influence to the environment: The HDPE is non toxic; no pollution to the soil. It is renewable and reusable.
