Strength Assessment of High-Pressure Ball Valve for Topside Process Unit Oh, Jeong-Sik; Kim, Yooil; Jeong, Nakshin; Kim, Sangmyung;
A high-pressure ball valve was developed, and both the structural strength and sealing performance were assessed based on a nonlinear finite element analysis. Different parts were modeled with solid elements and assembled, taking into account both contact and sliding effects. Three different loading scenarios were analyzed, including a high-pressure closure test and fire and shell test conditions. The structural safety of each part was checked under each loading condition, and the sealing performance was also investigated to validate the performance of the valve.
