Análise estrutural comparativa de junções flangeadas de válvula de esfera tipo Trunnion utilizada na indústria de óleo e gás conforme as normas ASME VIII e Norsok Standart L-005

Abstract

This research presents a comparative structural analysis of flanged joints of Trunnion valves toward ASME VIII and Norsok L-005 standards, aiming material economy in its development. The main tool for this approach will be a finite element analysis on two models, according to established conditions. This relation will be made based on total stress, deformations and elastic stress analysis, as regarded at ASME VIII Standard Div 2 Cap 5. In addition, this study grant a better understanding of which forces and loads that each component is submitted. After performing all necessary simulations, the results led to the reasonable choice of the flange Norsok due factors such as mass reduction, compact construction and operation reliability.
