Steel tubes are used in the heat exchanger in the petrochemical plant or the steam generator in the fast breeder reactor. Since these steel tubes in the heat exchanger or steam generator are stored as a bundle by the support steel plate (baffle), it is necessary to inspect the existence of defects from the inside of each tube. In these steel tubes, the defects are generated between the steel tube...
Steel tubes are used in the heat exchanger in the petrochemical plant etc. Since these steel tubes are stored as a bundle by the support steel plate (baffle), it is necessary to inspect the existence of defects from the inside of each tube. In these steel tubes, the defect is generated between the steel tube and the baffle at the outer side of steel tube. In this paper, problems in applying the alternating...
The steel tube is used for heat exchanger in petrochemical plant. Since these steel tubes are stored as a bundle, it is necessary to inspect outer side defects on steel tubes from the inside of the tube. In this paper, the alternating flux leakage testing method using inner coil for detecting outer side defects is examined using 3-D FEM. It is shown that the inspection of outer side defect on steel...
