Product Details

Glass fiber reinforced plastic pipe

1.1. Product Introduction

The glass fiber reinforced plastic pipe is made of alkali-free glass fiber and its products as a reinforcing material and a thermosetting resin as a matrix material, and contains (or does not contain) a granular material core layer such as quartz sand. Construction of pipes. In addition to the advantages of ordinary glass fiber reinforced plastic pipes, glass fiber reinforced plastic pipe jacking has the characteristics of small jacking force, easy correction, no sinking head, and fast speed in the pipe jacking construction. Glass fiber reinforced plastic pipe jacking has universal applicability and significant advantages, and is the first choice for various pipe jacking constructions.

Note: 1. The initial deflection resistance of GRP jacking pipe with other ring stiffness in the range of 15000 N / ㎡ ~ 100 000 N / ㎡ with ring stiffness is determined by linear interpolation method.
2. When the ring stiffness is greater than 100 000 N / ㎡,
A deflection level = 0.6 × B deflection level (%)
In the formula:
D——The calculated diameter of the pipeline, the unit is millimeter (mm);
t——the wall thickness of the pipeline, the unit is millimeter (mm).
