The Design And Performance Of Pressure Pipe Liners Under Static And Cyclic Loading, Shanhai Guan

Doctoral Dissertations

Cured-in-place pipe (CIPP), is a widely used trenchless technology. Based on the current liner design method, American Society for Testing and Materials (ASTM) F2207-02, several aspects are studied for the effect on estimating the long-term performance of the liners.

While estimating the liner burst pressure, the effect from host pipe material properties, liner material properties, defect geometry, liner creep properties and loading condition should be considered. The burst pressure calculated based on the existing method is overestimated and this allows an increased risk of structural failure before the expected design life is reached.

Compared with cast-iron, a PVC host pipe …
