| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | We have been developing a novel non-contacting magnetostriction-based ultrasonic guided wave testing technique, utilizing magnetic properties of STPG370 pipes in thermal insulation. In this study, computational analysis using JMAG electromagnetic field simulator was investigated to give uniform and strong remnant field in a STPG370 tube with thickness of 1 mm, diameter of 34 mm, using a pair of electromagnets with C-shaped permalloy cores. Based on the simulation results, magnetization using a pair of electromagnets with C-shaped permalloy cores was demonstrated on a STPG370 tube with the same dimensions as the simulation model, and with length of 1000 mm. The magnetized parts of the tube were used as a transmitter and a receiver, in order to transceiver T(0, 1) mode guided waves. Above the receiver, a HTS-SQUID gradiometer was set to measure magnetic signals induced by the generated guided waves. As a result of all-round measurement on the tube, we successfully demonstrated that roughly uniform magnetic signal distribution due to the T(0, 1) mode guided waves was measured around the circumference of the tube. A tricky magnetization method was examined, resulting in that a bit stronger and more uniform magnetic signal distribution due to the guided waves were obtained using the method. | |
