摘要： The systems and methods of the invention pertain to analyzing steam generator tube data for the detection of wear. Further, the invention is capable of performing a comparison of current tube signal data to baseline or historic tube signal data, e.g., from previous and/or the first, in-service inspection of the steam generator. The systems and methods are automated and can generate results to show potential tube-to-tube contact wear areas as well as the progression of tube-to-tube gap reduction within a steam generator tube bundle. In certain embodiments, the invention is capable of comparing current and historical eddy current data to determine the difference that may be related to degradation or other interested phenomena, and of processing and trending historical comparison results to establish normal variance and detect abnormal variances.

摘要： The apparatus employs the remote field eddy-current (RFEC) inspection technique to electromagnetically measure physical parameters of a metallic pipe. RFEC devices inserted into and displaced along a cylindrical pipes may be used to measure the ratio of pipe thickness to electromagnetic skin-depth and thus allow for the non-invasive detection of flaws or metal loss. Typically these RFEC thickness measurements exhibit a so-called double-indication of flaws, an undesired artifact due to a double-peaked geometrical sensitivity function of the device.The method describes a means by which this double indication artifact may be removed by an appropriate processing of RFEC measurements performed by an apparatus specifically designed for this purpose. The invention is particularly well designed for applications in the oilfield industry.

摘要： An apparatus and method for detecting defects in a metal surface is disclosed. The apparatus is configured to move an eddy coil relative to an underlying metallic surface along a plurality of generally parallel and adjacent scan paths, and to receive from the eddy coil an oscillating signal induced at said coil as it is moved along each path. A representation of the received oscillating signal in relation to each one of a plurality of adjacent scan areas within each path is recorded, and a two-dimensional grid-like map showing the signal representations relative to each scan area is displayed. Defect location is facilitated by a further function of the apparatus and method, by which user input to an interface causes a light source to illuminate a selected part of the metallic surface.
