Dye Penetrant Testing (DPT), 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. This inspection technique is highly effective in identifying cracks, porosity, laps, seams, and other surface discontinuities in metals and non-metals.
DPT is extensively used across industries such as oil & gas, power plants, fabrication, automotive, aerospace, and heavy engineering to ensure product quality and structural integrity.
