Dye penetration testing
Dye Penetrant Testing (PT) is a simple and effective non-destructive testing (NDT) method used to detect surface-breaking defects in non-porous materials such as metals, plastics, and ceramics. It is particularly suitable for identifying fine cracks, porosity, laps, and other surface irregularities that may not be visible to the naked eye.
Del NDT Services
At Del NDT Services, our qualified technicians use both visible and fluorescent penetrant systems to provide accurate and reliable inspection results. The process involves applying a specially formulated dye to the surface, allowing it to seep into any defects, and then using a developer to draw the dye out, making flaws clearly visible under natural or ultraviolet light.
