NDT - Dye Penetrant Examination
The Objective
When dealing with exploitation licenses and preventive maintenance of technical installations, Non Destructive Testing and Examination are indispensable techniques. Dye Penetrant Examination (PT) also known as Liquified Penetrant Examination is a Non-Destructive Testing method.
The Solution
Dye Penetrant Examination involves applying a liquid to the surface of a material and leaving it to rest for a pre-determined period of time. The liquid, the so called penetrant can be either a color that is easily visible under normal lighting conditions or a yellow/green fluorescent color that requires special lighting conditions to be effective.
A fluid, the penetrant, is applied to the material surface. The fluid penetrates the defects. After some time the penetrant fluid is washed off the surface. With a developer applied to the now clean surface, the defects where the fluid has penetrated are made visible. These spots are called indications. Acceptance criteria define whether or not the indication is non-acceptable (a defect) or not.
Application Range
SGS Industrial Services utilizes Dye Penetrant Examination to detect clad layers, welds and heat affected zones.
