Application of an electromagnetic technique to the determination of the degree of corrosion damage to products made of nonmagnetic metals
Abstract
The paper deals with the application of an electromagnetic nondestructive corrosion-inspection technique to the determination of the overall corrosion and local pitting damage in nonmagnetic pipes carrying aggressive media. In this technique, phase measurements of the output signal of an eddy-current transformer are used to determine the residual (noncorroded) wall thickness. A major advantage of this contactless technique is that no special treatment of the external surface, such as paint removal, is required.
