ASME规范的设计安全系数及调整因素

Safety Factor and Its Adjustment Factorsin Design of ASME Code

本文介绍美国机械工程师学会(ASME)《ASME锅炉及压力容器规范》设计安全系数的变化历史,设计安全系数包含的因素,重点介绍了ASME第III卷安全一级设备设计系数取值的主要考虑因素,以及1999年第III卷安全二、三级设备安全系数由4调整为3.5的主要考虑因素。

This paper introduces the history of the change of ASME code design safety factor, the considerations of design safety factor, and focuses on the main considerations of ASME Volume HI safety class 1 equipment design factor value, andthe main consideration of class 2 and 3 equipment safety factor which is adjusted from 4 to 3. 5 involume in in 1999.
