Dye Penetrant

Dye Penetrant Inspection (DPI) is an effective means of detecting surface-breaking flaws in ferrous or non-ferrous materials.

These may be cracks, inclusions, voids or porous zones. The dye, either water or solvent-based, is drawn into the fault by capillary action. Surplus dye is then removed from the surface and a developer is applied, which draws out the dye and provides a clear surface indication of the fault.

DPI is just one of the proven techniques we use in providing fast, reliable solutions for clients needing to optimise usage of vital plant and equipment in challenging commercial environments.
