摘　　要：针对由于渗透检测工艺问题造成的漏检事故,根据ASME等系列标准,结合机组燃油、检验对象露天布置、环境温度高、检测材料特性与国内不一致等实际情况,改进了渗透检验工艺,发现了大量的设备缺陷。Aimed at the leakage accidents caused by the penetrant testing（PT）, an improved PT procedure was made and performed based on ASME and related codes, combined with the actural site such as oil, open-air testing erviroment, high erviromental temperature, and special material and so on the features of the units. A great deal of defects were detected.
