Liquid Penetrant Packs a Punch!

Dye penetrant testing is a non-destructive testing method used for detecting surface-breaking defects, such as cracks, pores, and seams. It involves applying a liquid dye (penetrant) to the surface, which penetrates any open surface defects. Excess dye is removed after a dwell time. Developer is applied to pull the dye out of defects and make them visible, and is commonly used on high-energy piping, drums, and pressure vessels. Helps identify defects that could affect integrity or safety. However, it requires clean, smooth surfaces for accurate results.
