Resumo

The oil and gas sector is one of the main consumers of industrial valves, which are essential devices for
managing liquid, gas, or mixed fluids, ensuring safety and production in this industry. Designed according to
international standards, valves undergo structural analyses with calculations to ensure reliability and safety,
considering the pipeline's pressure class. In this study, a NPS 6 trunnion-mounted split-body ball valve was
analyzed, with flanged connections between the body and the cover designed according to NORSOK L005 [5]
standard. Using the finite element method and ANSYS software, three analyses were applied: linear-elastic with
stress linearization, elastoplastic, and elastoplastic for localized deformations, following the guidelines of ASME
VIII, Division II code [7]. The study resulted in an optimized valve geometry concerning mass concentration in
the body-to-cover connection, meeting the strength criteria defined in the design by analysis methodology of
ASME VIII, Division II [7].
