在役铁磁性钢管远场涡流检测常用标准的分析和比较

Evaluation and Comparison of Standards for Examination of In-service Ferromagnetic Steel Tubes Using Remote Field Testing

介绍了远场涡流检测技术的发展历程和基本原理,从适用范围、检测人员和检测机构资质的规定、检测系统、对比试样管、灵敏度调节和辅助检测要求等方面对在役铁磁性钢管远场涡流检测三个常用的现行标准进行了分析和比较,并对该技术的标准化工作提出建议。

The history and basic principles of remote field eddy current testing（RFT） were briefly introduced. Three Standards for examination of in-service ferromagnetic steel tubes using this technique were evaluated and compared in six aspects. Some suggestions for standardization of RFT were also given.
