Abstract:The submarine pipe stopper is prone to failure at large pressure and high temperature conditions. This work focuses on the submarine pipe stopper’s sealing failure caused by excessive shear stress and high temperature. First, the working principle of the sealing device in the stopper was analyzed and its performance was verified through land and sea trials. Then a comprehensive evaluation model fit for the large working pressure was established by analyzing the rubber cylinder’s sealing performance and strengt… Show more
