Abstract

PURPOSE:To make it possible to easily execute high-accuracy supersonic flaw-detecting inspection for a wide range of piping system, by recording a supersonic signal from a supersonic flaw detector and a probe position signal from a flaw-detecting mechanism at the same time and conducting their analytical evaluation. CONSTITUTION:After a supersonic flaw detecting mechanism was installed in a given position on a pipeline 15, the installation initial value and the flaw-detecting condition are memorized by a data analyzing device 23. When a probe holder 9 is lifted and a probe 10 is continuously shifted while being pressed against surface of the pipeline, position of the probe 10 is detected by position detectors 11-14, and thus obtained data are put into a data collecting device 22 through an interface 25. Similarly, a supersonic signal from the probe 10 is put into the device 22 through a supersonic flaw detector 21. And the data analyzing device 23 calculates an absolute position of the probe 10, and at the same time, it also calculates a distance from the probe position to a flaw on the basis of a supersonic signal of a flaw. It is possible, by doing so, to easily measure exact position and size of flaw on pipes of various sizes.
