Magnetic Particle Testing (MPT)

A non-destructive method for detecting cracks and other discontinuities at or near the surface in ferromagnetic materials.  

By applying finely divided magnetic particles to a suitably magnetised surface the particles are attracted to regions of magnetic non-uniformity associated with defects and discontinuities. MPT is a sensitive form of non-destructive testing and can be used to detect minute cracks and discontinuities.

SST-NDT provides a variety of Magnetic Particle Inspection (MPT) services including dry powder, wet visible, wet fluorescent and examination using a yoke.

Working to applicable codes and specifications, SST-NDT can apply MPT on:

  • Offshore platform
  • Construction and maintenance of structures
  • Pressure vessels
  • Bridges
  • Cranes, tanks and tankers
  • Aerospace vehicles
  • Power generation equipment
  • Research facilities
