ACT’s Non-Destructive Testing systems utilize fluorescent penetrant inspection (FPI) to help you locate surface-breaking defects in all non-porous materials, such as metals, plastics, or ceramics. Our advanced systems provide detection of casting and forging defects, cracks and leaks in new products, and fatigue cracks on in-service components. Combined with ACT’s pre-cleaning and post FPI processing stages, compact and automated systems or semi-automated non-destructive testing systems deliver a complete solution to your Non-Destructive Testing requirements.
ACT Utilizes Advanced Fluorescent Penetrant Inspection (FPI)
PURPOSE OF FPI SYSTEMS
Ensure Component Integrity with Fluorescent Penetrant Inspection
Our non-destructive testing systems be used across a broad array of industries, including aviation, automotive, construction, oil and gas, manufacturing, mining, military, pharmaceutical, and power. Contact an ACT sales engineer to discuss waste minimization and custom features such as powered turntables and transfer of loads to make your non-destructive testing system the most efficient and productive that it can be.
DYE PENETRANT INSPECTION
What does the FPI Process Involve?
1. Section of material with a surface-breaking crack that is not visible to the naked eye.
2. Penetrant is applied to the surface.
3. Excess penetrant is removed.
4. Developer is applied, rendering the crack visible.

Application of Penetrant
Powder Puff or Electrostatic
Non-Destructive Testing System Process
The test surface is cleaned to remove any dirt, paint, oil, grease or any loose scale.
The penetrant is then applied to the surface of the component being tested. The penetrant will soak into any surface flaws.
All penetrant on the surface of the component being tested is removed, but penetrant trapped in cracks or defects remains in place.
After excess penetrant has been removed, a white developer is applied to the sample. The developer draws from defects out onto the surface to form a visible indication.
The inspection uses visible light for visible dye penetrant. Ultraviolet (UV-A) radiation, along with low ambient light levels are used for FPI examinations.
