摘要： An annular guide rail is detachably mounted in enclosing relation around a tubular member of piping to be probed for any flaws that might be present therein, and a flaw detecting unit, a circumferentially driving unit and an axially driving unit are movably arranged on the annular guide rail and interconnected by connecting means. The flaw detecting means includes an arm movable axially of the tubular member and supporting ultrasonic flaw detecting means. The circumferentially driving unit includes first driving means for moving the flaw detecting unit, circumferentially driving unit and axially driving unit circumferentially along the guide rail. The axially driving unit includes second driving means for moving the arm axially of the tubular member. A transmission mechanism is provided for transmitting the operation of the second driving means to the arm.
