NONDESTRUCTIVE INSPECTION DEVICE, AND DESIGN METHOD FOR COIL OF NONDESTRUCTIVE INSPECTION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a nondestructive inspection device capable of measuring noncontactly a corroded part and a wall thickness of a pipe, even if the pipe is heat-insulated by an insulating material, or the like.;SOLUTION: This nondestructive inspection device 10 includes a sensor 11 mounted on the pipe 21 via the insulating material 22, in the pipe 21 covered with the insulating material 22, and a measuring instrument 19 for driving the sensor 11. The sensor 11 can measure a dimension of the corroded part of the pipe 21 located in a position separated by a prescribed distance, and the measuring instrument 19 includes a personal computer 18 for computing the thickness of the corroded part in the pipe 21 by inputting an output from the sensor 11.;COPYRIGHT: (C)2007,JPO&INPIT
