RESULTS

ndamaged CPVC pipes serve as the ultimate pressure in this study's subsequent steps, and damage models will be developed based on burst pressure determined during the initial testing. While burst pressures of studied pipes with notches represent the ultimate residual pressure. During the experiment, the internal pressure rises continuously until the specimens rupture. As a function of time, we recorded the maximum pressure and its evolution using a digital system. Because of burst test, the CPVC specimens had two rupture form and nature as shown in Fig.6. U
