Liquid Penetrant Testing

SERVICE DESCRIPTION

Liquid penetrant testing is a Non –Destructive method for finding discontinuities that are open to the surface of solid and essentially non-porous materials. Indications of flaws can be found regardless of the size, configuration, internal structure, or chemical composition of work piece being tested and regardless of flaw orientation. Liquid penetrant can seep into (and be drawn into) various types of minute surface openings (reportedly, as fine as 4micro inch in width) by capillary action. Because of this, the process is well suited for the detection of all types of surface cracks, laps, porosity, shrinkage areas, lamination and similar discontinuities in welds, casting, forgings and other product forms. Dye penetrant inspection is used extensively for the testing of wrought and cast products of ferrous and non-ferrous metals and powder metallurgy parts..

In practice, the liquid penetrant inspection process is relatively simple. Equipment generally is simpler and less costly than that for most other NDT methods .When used on ferromagnetic steels, in some instances, the sensitivity of liquid penetrant test is better than that of magnetic particle testing.
