Magnetic Particle Inspection (MPI)

R.N DUCS INTERTIONAL LIMITED uses this process for detecting surface and slightly subsurface discontinuities in ferromagnetic materials such an iron, nickel, cobalt and some of their alloys.

Magnetic particle inspection is achieved by using either direct or indirect magnetization considering the direction of the electric current which may be either alternating current (AC) or direct current (DC) (rectified AC).

We perform MPI on a pipe line using “black or white” method to check the stress corrosion cracking.
