ASME B31.3压力管道应力分析相关条文的演进探讨

Discussion on Evolution of ASME B31.3 Pressure Piping Stress Analysis Provisions

本文从ASME B31.3-2016版工艺管道设计规范管道应力分析相关条文入手,结合相关资料,分析了规范中管道静力分析中的一次应力分析、二次应力分析的理论基础及其演进思路,并结合国内对应规范GB50316-2000(2008版)、GB/T 20801-2006的现实情况,给出了未来的升版建议。

This paper starts from the relevant provisions of ASME B31.3-2016 edition of the Process Pipeline Design Code for Pipeline Stress Analysis,and combined with relevant data,analyzes the theoretical basis and evolution of the primary stress analysis and secondary stress analysis in the piping static analysis of the code.Combined with the actual situation of the corresponding domestic standard GB 50316-2000(2008 edition)and GB/T 20801-2006,this paper proposes the suggestions for future version upgrading.
