Abstract:
ABSTRACT The PVC-C pipes are increasingly used in industry, particularly in the supply and distribution pipes of hot and cold water, because of the quality of their mechanical properties at high temperatures and their corrosion resistance. Throughout the life cycle of these materials, they are potentially subject to various attacks directly impacting their original mechanical characteristics; therefore a re-estimation of their residual life would be required under the predictive maintenance strategies. This article is an experimental comparison between two failure modes of a PVC-C DN50 PN25 pipe under burst pressure due to a circumferential and a longitudinal defect. We chose to materialize the defects as a groove machinated on a lathe to control and increment the different depth of the failure. This will give to the maintenance services concrete results confirming that the longitudinal defect on a PVC-C pipe is more dangerous than a circumferential one. Keywords: PVC-C, circumferential groove, longitudinal groove, bursting pressure, crack propagation, critical depth.
