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:
