BEST DETECTION & PERFORMANCE ON CRACK-LIKE ANOMALIES

Longitudinal weld anomalies and narrow axial internal and external corrosion can pose a severe integrity threat to Petrotech. Conventional MFL tools that apply the magnetic field in the axial direction do not provide reliable detection and sizing of such anomalies.
Petrotech Transverse Field Inspection technology is also magnetic flux leakage based. However, magnetizer sections installed in the inspection tool induce a flux field in the circumferential direction. The proven design and high magnetization of the TFI tools coupled with an extra-high circumferential resolution provide reliable detection and sizing of narrow longitudinally-oriented metal loss anomalies.

This magnetizer system design ensures detection and sizing of general type metal loss anomalies, the same as conventional MFL tools. However, it is also specially developed for the measurement of longitudinally oriented anomalies such as tunnel corrosion, longitudinal weld anomalies.

We run our Petrotech TFI tools as stand-alone tools. We can combine it with other inspection technologies, such as MFL, UT, geometry, and mapping.
