Dye Penetrant Inspection

Dye Penetrant Inspection

Dye Penetrant Inspection (DPI) is a NDT method used for detecting surface breaking defects such as cracks, porosity, corrosion, laps and bursts. The big advantage of DPI is that it can be carried out on a wide variety of materials, where as other surface inspection methods are limited to ferritic material only.

Dye Penetrant inspections continue to be an effective and reliable inspection method for components such as; castings, forgings, machined parts and welds.

The two main Dye Penetrant Inspection methods we carry out are;

Colour Contrast Penetrant Inspection - Used for site work. Portable equipment. Very versatile. Good value. Great results.

Fluorescent Penetrant Inspection - Workshop based. Fixed equipment. Very high sensitivity. Great for large components.

All of our experienced inspectors are level 2 certified by the British Institute of Non-Destructive Testing.

Inspection Standard - BS EN ISO 3452-1:2013
