摘要： Probe carrier drive assembly for moving a probe carrier without slip or creep in a steam generator tube so that a probe, which has an inspection device attached thereto and which is connected to the probe carrier, selectively rotates in place, follows a linear scanning path through the tube or follows a helical scanning path having a variable pitch. The probe carrier drive assembly comprises an elongated circular member and a drive mechanism engaging the elongated circular member for moving the elongated circular member axially and rotatably within the tube. The drive assembly further comprises motors coupled to the drive mechanism for operating the drive mechanism and includes a controller operatively coupled to the motors for operating the motors so that the elongated circular member selectively rotates in place, follows a linear path in the tube or follows a helical path having a variable pitch.

摘要： An apparatus is disclosed for inspection of tubing, and more particularly, the determination of the extent of erosion in the wall of a heat exchange tube of a nuclear reactor. An ultrasonic transducer assembly is movable axially and rotatably in a helical path for producing both thickness and position signals to provide a map of wall thickness.
