摘　　要：ASME规范案例2605于2008年10月出版,其目的是为了满足炼化行业中加氢工艺设备蠕变疲劳寿命设计的需要。2010年1月第1次修订,即ASME规范案例2605-1,目前,最新的版本为2015年6月第2次修订的ASME规范案例2605-2,这一版修订中有如下重要修改:温度上限由454℃(850℉)提高到了482℃(900℉);对上版有误的公式和表格数据及温度单位进行了修正;在蠕变棘轮的校核中引入了弹性分析来代替非弹性分析。将对ASME规范案例2605-2的分析步骤、修订要点和算法实现进行解读和探讨,为国内工程应用和规范修订提供参考。ASME code case 2605, which was published in October 2008, was aimed to meet the need of the creep fatigue life design of hydrogenation process equipment in the refining industry. This code case was revised for the first time in January 2010, that is, ASME code case 2605 - 1. The latest version is ASME code case 2605 -2 which was revised in June 2015. Some important revisions in the latest version are as follows ： raising the highest applicable temperature from 454 ℃ （ 850 °F ） to 482 ℃ （900 °F）. Re- vising some incorrect parameters, the temperature units and their corresponding formulas. Providing the e- lastic analysis instead of inelastic analysis for the creep ratchet checking. The analysis steps of code case 2605 -2, the main revisions and the implementation of the algorithm are presented and discussed, which can provide helpful references for domestic engineering application and standard revision.
