Remote Field Eddy Current Non-Destructive Testing for Pipes and Tubes

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 summarized 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.
