Abstract: An ultrasonic testing equipment includes an ultrasonic probe having a plurality of transducers arranged along a predetermined annular curved surface, a transmission/reception control unit that causes at least two transducers of the plurality of transducers to transmit the ultrasonic waves to and receive the same from a tubular test object and a ultrasonic testing waveform display unit which displays ultrasonic testing waveforms received by the selected transducers radially corresponding to the propagation directions of the ultrasonic waves transmitted from and received by the selected transducers. The waveform display unit displays the waveforms radially with a point of time corresponding to an echo on an incident point of the ultrasonic wave to the test object contained in the waveform as a beginning point and displays circles indicating points of time corresponding to the echo on the internal surface and/or the external surface of the test object around the beginning point.

Abstract: A ultrasound flaw probing device (100) is provided with a ultrasonic probe (1) with a plurality of vibrators (11) arranged along a predetermined circular curved surface, a transmission and reception control means (2) that selects at least two or more pieces of the vibrators to carry out the transmission and reception of a ultrasonic wave for inspecting a tubular subject member (P) to be probed, and a probing waveform display means (3) that radially displays a probing waveform received by the selected pieces of the vibrators arranged in accordance with propagation directions of the ultrasonic transmitted and received from the vibrators.
