Dye Penetrant Inspection (DPI), also known as Liquid Penetrant Testing (LPT), is a widely used Non-Destructive Testing (NDT) method for detecting surface-breaking defects in non-porous materials without causing any damage to the component. The process uses visible or fluorescent penetrant liquids to identify cracks, porosity, leaks, and other surface discontinuities with high sensitivity and accuracy.
This inspection method is suitable for a wide range of materials and components, including welded joints, castings, forgings, machined parts, pipes, and fabricated structures. Dye Penetrant Inspection helps ensure product quality, structural integrity, and operational safety across various industrial applications.
