Magnetic Flux Leakage
(MFL) Inspection

PIPECARE Magnetic Flux Leakage inspection supports reliable detection and sizing of general corrosion, pitting, axial grooving, slotting, and other metal-loss anomalies in ferromagnetic pipelines. MFL is a proven in-line inspection technology used across a wide range of pipeline diameters, media, and operating conditions.

Magnetic Flux Leakage MFL pipeline inspection technology

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.
To clients who operate pipelines that are difficult to inspect, we offer our customized solutions for the following pipeline conditions:
  • Low pressure
  • Low flow
  • High temperature
  • Heavy wall thickness
  • Sour product
  • No pig traps or single-point entry
