Dye Penetrant Testing (PT)
Dye Penetrant testing (PT) is used to reveal emerging surface defects such as cracks on the surface of all non-porous materials. PT detects cracks, chips, porosity, pitting, etc. on parts at different stages of manufacturing, during preparation for welding and during welding. PT detects metal fatigue (fatigue cracks), pitting & etc. on installations in service.
