标准中关于拔制三通开孔补强计算方法的对比

摘要

国内关于油气输送用拔制三通的设计计算所采用的标准主要有GB/T50251-2003《输气管道工程设计规范》,GB/T50253-2003《输油管道工程设计规范》,SY/T 0510-2010《钢制对焊管件》以及ASME B 31.3-2010《Process Piping》等,但各标准关于三通的设计计算方法稍有差异.对4种标准中关于拔制三通开孔补强计算方法进行了对照,指出各标准的异同,并通过实例计算对其结果进行了对比,可为工程设计计算及校核计算提供参考.%The standards for designing extruded tee used for transporting oil and gas in China domestic main include; GB/T 50251-2003 Code for Design of Gas Transmission Pipeline Engineering, GB/T 50253-2003 Code for Design for Oil Transportation Pipeline Engineering, SY/T 0510-2010 Steel Butt-welding Pipe Fitting, and ASME B 31.3-2010 Process Piping,but the methods of design calculation in each standard have slight difference. In this article, it contrasted the calculation method in the above 4 mentioned standards, pointed out the similarities and differences. And the calculation results were compared through practice example, it can provide reference for engineering design and check calculation.
