Fracture analysis of defect Chlorinated Poly Vinyl Chloride pipes based on burst pressure and prediction their fraction of life

Most Chlorinated Poly Vinyl Chloride (CPVC) resins contain 63-69 % chlorine, in particular those used for the extrusion of plumbing tubes, due to this chlorination basic PVC, CPVC offers a mixture corrosion resistance and low installation costs its main applications requiring service non-ambient conditions. replaces copper owing economic gain by virtue pressure characteristics. In article, we have been interested fracture analysis damage modeling tubes subject samples burst tests. We performed set tests on virgin artificially damaged pipe at different notch lengths, then submitted specimens tests, addition recording time during these use conducting study. The results were exploited estimate reliability material, two parameters allow us follow degradation pipes used; subsequently, determined new relationship between through fraction life. This makes it possible predict moment acceleration intervene right engaging predictive maintenance.
