HomeServices Magnetic Particle Inspection (MPI)

We provide MPI of ferromagnetic pipe and pipe welds to the highest standards of quality and excellence

Magnetic particle inspection (MPI) is one of the most widely used non-destructive testing methods for identifying both surface and near sub-subsurface defects on ferromagnetic pipe and pipe welds. After a magnetic field is introduced into the object, iron fillings are dusted onto the surface to be tested. The fillings will cluster along edges of a flaw to reveal cracks or other defects.

With our vast branch network, we can mobilize a magnetic particle inspection team to virtually any project location. Because extensive training is vital to ensure proper magnetic particle testing, Shaw Pipeline Services provides all technicians with thorough instruction on the implementation of pre-approved MPI techniques and the resulting interpretation.

DIVERSIFIED METHODS

Maximizing MPI in conjunction with other non-destructive methods:

  • Dry Powder
  • Contrast Technique
  • Wet Fluorescent Magnetic

HIGHLY TRAINED TECHNICIANS

Armed with many hours of training and adhering to all MPI best practices and standards, Shaw Pipeline Services technicians ensure:

  • Proper alignment between magnetic flux and the defect
  • Post-inspection demagnetization as necessary
  • A thorough evaluation and interpretation of anomalies
