管道支管连接补强及计算

Reinforcing Calculation for Branch Connection

管道设计中,支管连接方式的确定为管道设计重要内容。主要探讨在不能选用标准管件、需要通过焊接支管连接时,焊接支管补强形式的确定及补强面积计算。同时综合ASME、GB、SH标准对管道补强的相关规定,对焊接支管连接及补强计算中需要考虑的其他因素做了阐述。

In design of pipeline, the selection of branch and host pipe connection structure is an important content. In this article, selection of welded reinforcing structure for branch and calculation of reinforcement area were discussed for the condition where standardized fitting cannot be applied. At the same times, summarizing the relevant requirements in ASME, GB and SH standards, the factors which are needed to take into account in welded branch connection and reinforcement were expounded.
