FRP jacking pipe FRP jacking pipe is an advanced composite material pipe with three-dimensional enhanced structure which is made by 3D printing technology and continuous winding process. Pipe Expansion Joint The pipe has axial reinforced short cut glass fiber which improves the axial compression strength. The products are widely used in fluid transportation fields such as municipal water supply and drainage, marine engineering, and petrochemical. Performance feature FRP jacking pipe not only has the basic advantages of light, high strength, corrosion resistance and excellent hydraulic properties like glass reinforced plastic pipe, but also has the following characteristics. 1. High axial compression strength, high allowable jacking force The index value of axial compression strength ≥85MPa, The typical value is about 95 Mpa, the allowable jacking force is greater than that of the traditional pipe, the distance between the two operational wells can be l…
