The present invention refers to magnetic foreign number deficiency flaw detection device against easy wetting ability, more specifically small diameter pole inside testing device or partial saturation type eddy current type testing for nondestructive inspection of a heat pipe of magnetic foreign material can be a stand-alone number pertaining to deficiency flaw detection device having a construction are disclosed. Thin metal wall tube with the object of transferring thermal energy by hot and cold as a boundary to flow medium are used. The high temperature, high pressure, foreign, medium flow and by the chemical reaction heat transfer tube metal wall crack, corrosion is controlled or deficiency can be. The heat transfer tube of a heat pipe of a small diameter generally composed of bunches of deficiency flaw detection device accessible since while illuminated difficult. The, inspecting a deficiency flaw detection device from the interior of the heat transfer tube insertion is generally disclosed. On the other hand, since a predetermined thickness of the heat transfer tube of a heat pipe of corrosion and wear resistant remains until the next inspection period can allow when hereinafter. However, in the case of interchangeable performing maintenance such as fatigue crack of a heat pipe of accomplishing. The, of a heat pipe of corrosion, wear and fatigue crack accurately to determine the need to quantitatively evaluating flow tides. For a conventional infrared techniques, bobbin type coil or annular or cylindrical magnetic sensor arranged magnetic sensor arranged non-destructive testing has been developed using heat transfer tube. On the other hand, when the heat transfer tube of a heat pipe of said ferromagnetic material is measured waveform necessary for measuring region, generated around a deficiency by measuring and evaluation of the distribution of the penetrated deficiency generally detecting method are disclosed.
