本报告包含了计算管道中喷嘴局部应力规则的建议和支持数据 由于外部荷载和压力而形成的壳体和封头。本报告的目的是计算D/T范围为7到2500的喷嘴和壳体中的局部应力， d/d范围从0到0.7，t/t范围从0.1到10。根据ASME BPVC第八节第2部分-压力容器制造规则评估局部应力的规则- 还提供了替代规则，以及与其他相关性、有限元结果和测试数据的验证比较。考虑了衬垫加固喷嘴，但几乎没有可用的验证。应谨慎使用衬垫加强型喷嘴指南。

This report contains recommendations and supporting data for rules to compute local stresses in nozzles in shells and formed heads due to external loads and pressure.The purpose of this report is to compute local stresses in nozzles and shells in the D/T range from 7 to 2500, the d/D range from 0 to 0.7 and the t/T range from 0.1 to 10. Rules for the evaluation of the local stresses in accordance with ASME BPVC Section VIII - Division 2 - Rules for Construction of Pressure Vessels - Alternative Rules are also provided along with validation comparisons against other correlations, finite element results and test data. Pad reinforced nozzles are considered but little validation is available. Pad reinforced nozzle guidelines should be used with caution.
