摘要： PROBLEM TO BE SOLVED: To provide an ultrasonic thickness-measuring device that can recognize the wall thickness value of a pipe measured for each ultrasonic probe and can accurately measure the thickness, without being affected by the outside diameter of the pipe.
SOLUTION: The ultrasonic thickness measuring device comprises a master truck 13 traveling on the outer peripheral surface 12 of the pipe 11; a range finder 14 for measuring the travel distance of the master truck 13, a plurality of slave trucks 15A-15L moving with the master truck 13, while covering a constant-width region in a direction orthogonal to the circumferential direction of the outer peripheral surface 12; ultrasonic probes 16A-16L arranged in respective slave trucks 15A-15L, ultrasonic flaw detectors 17A-17L for transmitting an operation signal to the ultrasound probes 16A-16L, receiving the output signal, and outputting it as a waveform signal; and a data processing machine 18 that calculates the minimum wall thickness of the pipe 11, by converting each waveform signal into a digital signal, determines the wall thickness distribution of the measured position of the pipe 11 for each of the ultrasound probes 16A-16L, based on the output signal of the range finder 14 and the minimum wall thickness, classifies them according to hierarchy, and displays them color by color.
