摘要

Indicates increased load carrying capacity for several flanges based on separate stress limiting criteria. These stress limiting charts were not provided separately in the original work in API Bulletin 6AF, which combined them with leakage criteria. The three-dimensional model analyses of this study provide verification that exisymmetric finite elements results of flanges, as used in Bulletin 6AF, are conservative. Additionally, this study determined a few flanges to have less loading capacity than originally defined in API Spec 6A for makeup loading, and thus have been reduced to meet design requirements. 表示根据单独的应力限制标准，多个法兰的承载能力增加。API公告6AF的原始工作中没有单独提供这些应力限制图，该文件将它们与泄漏标准结合起来。本研究的三维模型分析验证了公告6AF中使用的法兰对称有限元结果是保守的。此外，本研究确定，一些法兰的承载能力低于API Spec 6A中最初定义的补给荷载，因此已降低，以满足设计要求。展开▼
