摘　　要：文章比较分析了压力管道腐蚀缺陷剩余强度的评价方法,其中包括ASME B31G-1984、ASME B31G-1991、DNV-RP-F101、PCORRC以及有限元方法等5种计算方法。这些标准或方法形成于不同时期,并且针对的管道强度等级也不尽相同。旨在便于评定人员选取合适的评价方法,进而提升管道安全运营管理水平。The Remaining strength assessment methods for corroded pipelines such as ASME B31G-1984, ASME B31G-1991, DNV-RP-F101, PCORRC and finite element method were reviewed. These method or standards formed at difl＇erent times, and the intensity level for the pipeline were not the same. Its aims is to facilitate the assessment of personnel to select the appropriate evaluation methods, and thus enhance the operation and management of pipeline safety standards.
