Investigation of Sealing Performance with Bolted Flange Joints with Gasket using FEA Method
Main Article Content
Abstract
In pressure vessel and pipe systems, gasketed flange joints are quite frequent and are also used in oil and gas wellheads and trees as spool end connections. Flanges are most commonly employed when a joining or disassembling junction is required. The process industry has long been concerned about leakage in gasketed flanged junctions. The installation and stress factors of a gasketed flange joint directly affect its sealing effectiveness. API 6A type 6B flange with a maximum pressure rating of 20,000 psi is examined in this study using API design procedures. Due to the symmetricity of the 8 bolted flange, a 45 section is taken for analysis. The findings of a parametric analysis of flange behaviour and bolt stresses are investigated by altering the bolt preload and internal pressure while keeping other flange independent variables constant.
