Scope of this paper is to study the flange to Gasket joint under bolt tightening &amp; operating condition as per the guidelines specified in ASME-PCC 1 Appendix-O using FEA approach with ANSYS as FEA tool. Contact pressure for various transient loading conditions is obtained &amp; compared against the required minimum contact pressure for the leak proof joint.Flange joint assembly leakage in the pressure vessel industry is big issue for monetary losses. Main reason behind the leakage is rotation of flanges. Therefore, flange joint design must be optimized while keeping flange rotation in focus also and not just flange thickness only. One way to do that is using the guidelines of ASME PCC-1 Appendix-O. &nbsp;&nbsp;ASME-PCC 1 gives the guidelines for bolted flange assembly for pressure vessel and piping joints in a standardized manner but with the help of FEA tools simulation can be done and broad picture of the assembly can be look upon so that a designer engineer can have better insights for the stress and deformation during seating and operating conditions.Thorough investigation of the flange joint has been carried out with design by analysis in this paper and acceptance criteria as recommended in ASME PCC-1 Appendix-O has been used to establish the design in safer and optimized way. &nbsp;&nbsp;&nbsp;

ASME 2021 Pressure Vessels & Piping Conference (PVP2021)

Supporting the need among researchers worldwide for additional online and multimedia content, ASME now offers the ASME Conference Video Collection. This platform will collect and provide long-term access to conference presentation videos, encompassing all technology areas within ASME's technical conference and events program. About 30,000-40,000 engineers across all mechanical engineering and related disciplines participate in ASME conferences each year. This includes authors of approximately 6,000 to 8,000 technical papers published by ASME, the majority of whom also submit video presentations for our virtual conferences. The video collection will be available as an add-on to existing product packages or as a separate subscription.
