Liquid penetrant testing

The liquid penetrant testing also called dye penetrant testing (PT) is one of the oldest non-destructive surface crack-testing methods. This test benefits from the capillary effect of material cracks open towards the part surface.

The NDT-technician applies dye on the part surface which penetrates into the cracks where it remains inside the material cracks even after the part surface has been cleaned. A developer, being applied after the cleaning of the part surface, extracts the dye from the material cracks. Due to this kind of "bleeding" the cracks become visible on the surface.

The liquid penetrant testing (PT) is suitable for the surface crack testing of almost all materials. It is broadly used in the industry so that we may desist from listing the great variety of applications.

If you have any questions about our PT testing service, contact us now. We will be pleased to advise you!
