DPT, or Dye Penetrant Testing, is a non-destructive testing (NDT) method used to detect surface-breaking defects in non-porous materials. It's also known as Liquid Penetrant Testing (LPT) or Dye Penetrant Inspection (DPI). The process involves applying a special dye to the surface, allowing it to seep into any flaws, and then using a developer to draw the dye out, making the defects visible. | VARCO Engineering Services Pakistan
