MAGNETIC PARTICLE TESTINGSERVICES HYDERABAD
Track Discontinuities in Ferrous Materials before it get delayed, …
Surface and subsurface flaws in ferrous materials can lead to component and production slow down but are often not simple to spot in time.
STARNDT services offers magnetic particle inspections (MPI) – a non-destructive testing (NDT) method for detecting discontinuities in ferrous materials. We can determine a part’s serviceability or similarity to required benchmarks, sparing you future costs and delays.
Our technicians are trained and certified as per standards and are capable of analyzing the best ndt method for your component

Magnetic particle Inspection (MPI) is a non-destructive testing (NDT) process for detecting surface and shallow subsurface discontinuities in ferromagnetic materials such as iron, nickel, cobalt, and some of their alloys. The process puts a magnetic field into the part.
The piece can be magnetized by direct or indirect magnetization. Direct magnetization occurs when the electric current is passed through the test object and a magnetic field is formed in the material. Indirect magnetization occurs when no electric current is passed through the test object, but a magnetic field is applied from an outside source.
The magnetic lines of force are perpendicular to the direction of the electric current, which may be either alternating current (AC) or some form of direct current (DC) (rectified AC). The presence of a surface or subsurface discontinuity in the material allows the magnetic flux to leak, since air cannot support as much magnetic field per unit volume as metals.
To identify a leak, ferrous particles, either dry or in a wet suspension, are applied to a part. These are attracted to an area of flux leakage and form what is known as an indication, which is evaluated to determine its nature, cause, and course of action, if any.
The method is applicable to all metals which can be strongly magnetized – ferritic steels and irons, but not generally austenitic steels.
