工业金属管道压力试验压力计算及盲板选用

工业金属管道是压力管道的一种，在石油化工、电力等行业应用广泛。通过对工业金属管道设计参数的物理意义、计算公式以及现行规范中有关管道压力试验条款的介绍和分析，结合实例解释了试验压力计算的方法与比较原则。对试压用盲板厚度的选用进行了探讨，介绍了几种盲板计算方法以及利用电子文档建立函数的快捷计算方法，可为解决管道系统试压中盲板选用问题提供理论依据和方法。

Calculation of Test Pressure for Industrial Pipeline and Selection of Blank Flange

Pressure pipeline is one of the industry metal ones and widely used in petroleum and chemical, and electricity power industry. The introduction and analysis were made for physics importance, calculation formula, and the test requirement listed in current codes. The test pres sure calculation and the comparison were interpreted as well. Discussion of blank flange thickness was performed for pressure test. Several calculations for blank flange and shortcut for E-file es tablishment were introduced, which can be used as the reference for the selection of blank flange.
