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.

用有限元法研究带垫片的螺栓法兰连接的密封性能

在压力容器和管道系统中，垫圈法兰连接非常常见，也用于石油和天然气井口和采油树的阀芯端连接。当需要连接或拆卸连接处时，最常使用法兰。过程工业长期以来一直关注密封法兰连接处的泄漏问题。垫片法兰连接的安装和应力因素直接影响其密封效果。本研究使用API设计程序对最大额定压力为20,000 psi的API 6A型6B法兰进行了检查。由于8螺栓法兰的对称性，采用45度的截面进行分析。通过改变螺栓预紧力和内压力，同时保持其他法兰独立变量不变，对法兰行为和螺栓应力的参数化分析结果进行了研究。
