Magnetic particle test is precise method for examination of metals and welded joints. It provides detection of the smallest surface and subsurface defects. It is employed at construction and operation stages to detect defects in ferromagnetic materials.

Specific aspects of magnetic particle testing by “Center of industrial diagnostics and control” LLC

Basis of magnetic particle test is registration of stray magnetic field using ferromagnetic powder or magnetic slurry as an indicator. Action principle lays in generation of magnetic flow in product. At that on defect-free areas the flow does not change its direction. If it encounters on its way areas with reduced magnetic permeability, for example discontinuities in metal (cracks, nonmetal inclusions etc.), then magnetic field occurs which tries to attract the maximum possible number of particles to damaged area.

“Center of industrial diagnostics and control” LLC performs magnetic particle test to detect surface and subsurface integrity damages of metal spread inside of the product: cracks, flakes, incomplete penetrations, pores. Works can be performed on thermal and nuclear power objects, as well as industrial objects of metallurgy, oil & gas, chemical and other industries.
