A magnetic sensor was developed by Southwest Research Institute (SwRI) to measure stainless steel cladding thickness. Applications include:
According to ASME Section XI, evaluation of flaw acceptability requires that the depth of the flaw into the base metal be determined. Ultrasonic inspection measures only the total flaw depth from the examination surface; however, the needed base metal depth can be found by subtracting the thickness measured by the clad sensor.
The sensor can be used for manual measurements or can be incorporated into a mechanized scanning system with automated data acquisition system. The sensor was used successfully during an in-service inspection of a commercial nuclear reactor pressure vessel using the SwRI EDAS® system.
The system has also been used to inspect petrochemical vessels. Sensors can be configured in various sizes to accommodate accessibility requirements.
