TFI ensures detection and sizing on certain anomalies that conventional axial MFL technology face with difficulties.
Our TFI tools can optionally be equipped with IMUs to carry out pipeline mapping simultaneously.
TFI has the highest effective resolution, both axial and circumferential, ensuring the best sizing accuracy within the natural limitations of magnetic inspection technology.
