Magnetic Flux Leakage – MFL

Vision Integrity provides Magnetic Flux Leakage (MFL) throughout Western Canada and has several dispatch locations operating 24/7.

Magnetic Flux Leakage is nondestructive testing method that can detect metal loss, such as corrosion, in steel structures. MFL is primarily used to examine pipelines and storage tanks to assess the integrity. MFL can detect corrosion on pipe walls, tank floors and tank walls.

MFL testing uses advanced computerized technology to find corrosion areas. The equipment uses electromagnets to induce a magnetic field and the results are then analyzed and recorded. By magnetizing a ferrous material, technicians can determine if the material is corroded based on if the magnetic flux material is disturbed or undisturbed.

Advantages of Magnetic Flux Leakage Testing

  1. This method of nondestructive testing is quicker compared to conventional UT.
  2. It is a cost-effective method.
  3. Capable of scanning through most coatings.
