GRP Jacking Pipe

GRP Jacking Pipes are designed to meet the exacting demands of pipeline construction and rehabilitation using micro-tunnelling and pipe-relining methods.

Advantage of GRP Jacking Pipe

1. Corrosion resistance, maintenance free, long service life (more than 50 years)

2. Large conveying flow (GRP pipe N= 0.009-0.01; concrete pipe N= 0.013-0.014)

3. High strength and large longitudinal jacking force (GRP pipe ≥ 90Mpa)

4. The friction resistance between pipe wall and soil is small, and the construction jacking force is small

5. Light weight and convenient transportation and hoisting. For example, DN2000 concrete pipe jacking is 3499kg/m, while DN2000 GRP pipe jacking is 850kg/m.

6. Construction Earthwork can be reduced by 30% compared with concrete pipe

7. The construction speed is fast, which is three times that of concrete pipe

8. Strong differential settlement resistance

9. Pipeline that can be used for pressure transmission medium

10. It can transport highly corrosive media
