管道远场涡流无损检测技术综述

摘要

Remote Field Eddy Current ( RFEC) is an important branch cut of eddy current nondestructive testing ( NDT) technique, and draws more and more attention in the testing and repairing of pipes and tubes. The origin and development history of RFEC technique was described. The research status and hot-spot issues of RFFC technique both inland and overseas were sum-marized and analyzed. The future development direction of RFEC technique was discussed with detail, from the aspects such as axial crack detection ability improvement,mounting plate influence in use and so on.%远场涡流作为涡流无损检测技术的一个重要分支，目前在各个行业的管道日常维护和安全保障中发挥着重要的作用。文中首先详细叙述了远场涡流无损检测技术的发展历史；对目前国内外远场涡流应用的研究现状和研究热点问题进行了总结和论述；从进一步提高轴向裂纹检测能力，解决使用中支撑板影响问题等方面，探讨了远场涡流无损检测技术的应用发展方向。
