国际化工项目中压力管道支管补强计算的探讨

Discussion on Reinforcement Calculation of Pressure Pipeline Branches in International Chemical Engineering Project

根据ASME B31. 3-2016标准中关于压力管道支管补强计算的规定,论述了标准中支管补强计算的依据、适用范围,通过一个工程实例来分析说明如何确定支管表中需要计算的部分、详细的计算方法及如何判定补强计算。通过工程实例分析设计过程中容易犯错误的地方,达到深刻理解标准要求,为管道设计提供合理的、满足标准规范要求的支管连接。

According to the provision of ASME B31.3-2016 standard on the reinforcement calculation of pressure pipeline branch pipe, this article discussed the basis and scope of application of the reinforcement calculation of branch pipe in the standard. Through an engineering example, it analyzed and explained how to determine the part of the branch pipe list that need to be calculated, the detailed calculation method and how to determine the reinforcement calculation pass. Through the analysis of Engineering examples, the error-prone areas in the design process can reach a deep understanding of the standard requirement, and provide a reasonable branch pipe connection to meet the requirement of the standard specifications for pipeline design.
