Abstract
Among the various industrial sectors, the Oil & Gas industry is one of the main consumers of valves. These devices are used in the management of fluids in liquid, gas, or mixed states, playing a fundamental role in the production and safety of installations. Industrial valves are designed according to requirements of international standards and technical specifications that require analytical structural calculations to provide adequate levels of reliability and safety for the installations, according to the pipeline pressure class. Among the parts of this equipment, the flange system of the body and its bolted union have extreme importance in ensuring the ability to contain the fluid pressure internally within the equipment casing. In this context, the present study presents a calculation methodology based on the ASME code for sizing the flanged union of an onshore application ball valve. A case study will be addressed, related to the sizing of the flanged union of the body of an industrial trunnion ball valve, nominal passage diameter of 6”, pressure class 600, and ASME 16.34 and API 6D construction standards. The analytical calculation methodology will be complemented by finite element method analyses, including linear elastic and elasto-plastic analysis, using ANSYS software following ASME VIII, Division II guidelines. The aim of this study is to propose a valve with constructive characteristics that meet the required safety criteria and to present a reference work for assistance in the sizing of these important equipment to the academic and industrial community.
