Liquid Penetrant


Liquid Penetrant Inspection is utilized for both ferrous and non-ferrous materials to detect the defects that outcrop at the surface of a component. Penetrant inspection is typically used when magnetic particle inspection can not be performed. The process of this inspection includes spraying a component with penetrant, then developing it with either a red dye, that is visible in natural light, or a fluorescent dye that can only be seen in black light. Like MPI, penetrant can be used in the field or laboratory and it t is a cost effective way to test large quantities of small parts efficiently and effectively. 


Canyon State Inspection Inc. performs all types of penetrant inspections including Types 1, 2, & 3, Methods A, B, C, & D. We maintain stationary fluorescent penetrant inspection lines in both of our labs and are equipped with all necessary tools to perform this method on all types of job sites. Penetrant is an incredibly effective inspection tool for many industries including aviation, aerospace, mining, missile, pipeline, and welding.
