Detailed Product Description

PVC-U pipe:
1.DN200mm-DN500mm
2.Project performance: Beijing Olympic Games (bird's nest / National Swimming Center)

PVC-U pipe:

Product features:
1. Annulus bellow structure, excellent mechanical performance with hardness and softness, high strength, press resistance, bend resisitance and impact-proof.
2. The pipe with smooth inner wall, large water flowing amount, small fluid friction resistance, large transprortation amount, no fouling is the ideal drainage pipe. It can be used for the cable jacket pipe materials. The pipe is of good electrical insulation performance, fire retardancy and long duration. In addition, the cable lien can operate safely and reliably.
3. Stable chemical performance, outstanding performance, including erosion resistance, innocuity,contamination free, and environment protection.
4. The hollow rib structure and light weight realize the convenient construction and greatly
lowered construction cost.
5. Working temperature scope:-60°C -- +45°C
6. The pipe is soft in a certain degree, adapts to the sedimentation of the uneven soil. With the
proper bending degree, the pipes can be directly paved in the channels with straight curves.
7. The service life is as long as more than 50 years.
8. 100% recycle for reuse can save the resources and protect the environment.

Primary purpose:
1. City planning engineering rain water and sewage discharge
2. Residential quarter’s sewage dischage
3. Industry and mining enterprises’s ewage dischage
4. Low-pressure water transportation of the water irrigation projects and running water
5. Ventilation system
6. Cable and wire jacket
