摘　　要：为了使管道工程师在国内国际项目中更好的选用法兰,对于国标、化工行业、石化行业、美标和欧标主要压力管道法兰标准,结合实际项目中的使用经验,介绍了每种法兰标准的尺寸范围、压力范围、法兰类型及密封面型式,指出了压力管道法兰的选择依据及注意事项以及各标准之间的差异,通过对比发现,目前世界上主要使用的两大管法兰标准是美国的ASME法兰标准和欧盟的EN法兰标准,我国的法兰标准都是以这两个法兰标准为基础做出的。In order to help piping engineers to select flanges more properly, in this article, for several piping flange standards,including GB, HG, SH, ASME and EN, the applicable scopes of size and pressure, structure types, and sealing faces were introduced based on the practical engineering experiences. The principles and notes for flange selection, and the differences among these standards were indicated. Currently, there are two main flange standards used worldwide, that is ASME standard from USA and EN standard from Europe, and Chinese flange standards are based on these two kinds of standards.
