VIBRATION PROOF STRUCTURE OF FLAW DETECTION PROBE

摘要

PURPOSE:To prevent the lowering of the flaw detection performance due to vibrations of a cable and pressure receiving bodies by providing openings inside the pressure receiving bodies adjacent to a flaw detection probe before and after it. CONSTITUTION:Openings 30 are provided inside several pressure receiving bodies adjacent to a flaw detection probe 25 inserted into a heat exchanger tube 3. Here, the flow 27a of a fluid 27 runs into the openings 30. This can reduce a vortex area generated by the flow 27a along the outer surface of the pressure receiving bodies 24 thereby preventing vibrations of a cable 26 and the pressure receiving bodies 24 due to a vortex generated in the after flow of the pressure receiving bodies 24.
