Penetrant Testing Inspection systems
Delta Flux designs and builds systems and plants for Non-Destructive Surface Penetrant Testing Inspection for all test and verification applications in industry. With the Penetrant Testing Inspection system emerging discontinuities, where the contrast fluid can penetrate by capillarity, can be easily detected.

How the systems for Non-Destructive Surface checks with penetrating liquids work
The penetrating liquid control of surface defects (procedure indicated with the initials PT) is developed to allow the verification of components or structures made of any material, not requiring it to be ferromagnetic as in the case of Magnetic Particle Inspection, paying particular attention to high porosity
Liquid Penetrant is applied to the piece to be examined (after a thorough washing) by spraying, by brush, or by immersion. This process requires an adequate waiting time, necessary for the liquid to penetrate any surface defects by capillarity. The surface is then washed from excess Liquid Penetrant. Finally, a special developer or detector is sprinkled on the surface of the piece under examination which, after an adequate time of action, allows the fluid previously applied to resurface in correspondence with cracks and discontinuities. This will allow the operator to detect the presence of surface defects in the piece by careful visual inspection, with the naked eye or by lighting with an ultraviolet Wood lamp.
The advantages of surface checks with penetrating liquids
The fundamental advantage of the Liquid Penetrant surface examination method consists in the possibility of using it on components of any material, even non-ferromagnetic ones, and on pieces of any geometry. A further highly appreciated factor is the reduced equipment required to carry out the checks, especially on the move. It is in fact sufficient for the operator to carry the Liquid Penetrants, without the need for any additional devices.
