Liquid Penetrant Inspection

Liquid penetrant inspection is a non-destructive test which can detect surface breaking discontinuities even when a material is not ferretic (not magnetic) or where access is restricted. We can provide you with a PCN Level 2 LPI Operator to perform liquid penetrant inspection and advise on the necessary steps to get the components passed and back into service.

This application can be carried out in many forms (fluorescent, water washable, colour contrast) - we can advise you on which method is best to use for your needs. The results derived are determined by the correct application being used. We can audit visual inspections using this technique however is is most popular for weld testing or casting testing.
