RELIABLE, SIMPLE, AND EFFICIENT

We use MFL for detection and sizing of general corrosion and other metal loss anomalies, especially circumferentially oriented. MFL tools have limited capability of detection and sizing of girth weld anomalies. Over the years several generations of the MFL systems have been subsequently developed involving significant improvement of their performance specifications.
