Penetrant testing

Introduction of a testing method utilizing capillary action when the infiltrating liquid seeps out of the wound.

The "penetrant testing" is a suitable method for detecting surface-opening defects in test specimens. It utilizes the capillary phenomenon to allow liquid to penetrate, and when the penetrant is applied, it seeps into surface cracks and other opening defects. After that, the excess penetrant is removed by wiping with a removal solution or rinsing with water, and a developer (white fine powder) is applied to draw out the penetrant remaining in the opening defects, thereby forming an indication pattern (penetrant indication pattern). It is widely used for both metals and non-metals and excels in detecting surface-opening defects, which are considered the most harmful. 【Features】 - Detects surface-opening defects in test specimens - Utilizes the capillary phenomenon for liquid penetration - Forms indication patterns (penetrant indication patterns) - Widely used for metals (both magnetic and non-magnetic) and non-metals (such as ceramics) - Excellent in detecting surface-opening defects *For more details, please refer to the PDF document or feel free to contact us.
