API 653 Tank Inspection Massachusetts

www.commtank.com/tank-articles...
This video shows the steps required to perform aboveground storage tank inspections utilizing both Magnetic Flux Leakage (MFL) scanner and Ultrasonic Test (UT) equipment. The MFL can scan large areas of steel quickly and provide and audio alarm when corrosion is encountered. The UT equipment measures the thickness of steel through coatings. When the MFL flags a questionable area the UT equipment is used to measure each corroded area to determine how much steel is still present.

This is misinformation. That is not how a MFE machine works. The people in the video are doing everything properly, but the captions are explaining the process incorrectly.
This machine only detects a volumetric change in flux leakage. Not actual thickness loss.
