| Abstract: | The remote field eddy current (RFEC) testing for high conductive tubes, both ferrous and nonferrous, has the characteristic of through-transmission, so it is sensitive for the defect in the tube wall. The problem of rib tube(cooling rib or tube support plate) testing in industry was discussed. The effect of rib on characteristic of RFEC and defect response when inspecting the tube with rib by RFEC was analyzed, the relationship and pick-up method between signals of rib and defect response were obtained. |
