Following years of detail improvements on sensor technology and magnetic circuitry as well as significant progress in data analysis software, 3P Services has launched a new general MFL tool specification in January 2010. The new “Detection and Sizing Performance Specification”, as usual in the format as recommended by POF, is valid for all of 3P Services’ MFL inspection modules, whether configured as pure MFL or as combined tools. This also includes bi-directional MFL applications.
The POD (Probability of Detection) and sizing accuracy values, taken from numerous pull tests, have significantly improved. In particular, capabilities to detect and size “pinhole” type features, part of the domain of MFL superiority over UT technology, have again increased. Details on request.
