摘要
结合实际工程运用经验,将HG/T 20613-2009《钢制管法兰用紧固件》(PN系列)以及HG/T20634-2009《钢制管法兰用紧固件》(Class系列)两种系列中钢制管法兰紧固件的选用方法进行了归纳总结,以供设计、制造、施工、安装单位合理地选用法兰紧固件,进而达到提高工作效率、降低工程成本的目的。
Based on actual engineering application experience,the article summarizes the selection methods of steel pipe flange fasteners in the two series of HG/T 20613-2009 Bolting for use with steel pipe flanges(PN designated)andHG/T 20634-2009 Bolting for use with steel pipe flanges(Classdesignated),so that design,manufacturing,construction,installation and trading units can reasonably select flange fasteners.Then achieve the purpose of improving work efficiency and reducing engineering costs.
