Product Description

We have marked a successful niche in the market as a reputed organization engaged in offering Magnetic Particle Test. It is a nondestructive method for locating surface and near surface discontinuities in ferromagnetic materials. When the material is magnetized, discontinuities that lie in a cause leakage field to the direction of the magnetic field will cause a leakage field to be formed at and above the surface of the part. Magnetic Particle Test is provided to construction, aerospace, automobile and metallurgical industry. We offer this service at cost effective rates. 


  • Detection of discontinuities
  • Successfully detects surface and near surface defects
  • Timely execution

Magnetic particle Inspection/Test (MPI) is a non-destructive testing (NDT) process for detecting surface and subsurface discontinuities in ferrous materials. The process puts a magnetic field into the part. The piece can be magnetized by direct or indirect magnetization. Direct magnetization occurs when the electrical current is passed through the test object and a magnetic field is formed in the material. Indirect magnetization occurs when no electrical 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 electrical 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. Ferrous iron particles are applied to the part. The particles may be dry or in a wet suspension. If an area of flux leakage is present the particles will be attracted to this area. The particles will build up at the area of leakage and form what is known as an indication. The indication can then be evaluated to determine what it is, what may have caused it, and what action should be taken if any.
