Dye Penetrant Testing
Our laboratory performs Liquid Penetrant Inspection on a wide range of materials and applications, both in-house and on-the-field locations. Penetrant testing is used to test ferrous and non-ferrous materials such as aluminum and stainless steel. Liquid penetrant inspection has been an industrial testing standard and it is one of the most reliable, efficient, and cost-effective methods for detecting surface flaws in non-porous materials that may not be detected by standard visual inspection methods. As in the magnetic method, PT testing can be perform in visible or ultraviolet light. Different testing methods are available ranging from visible red/water washable penetrant systems to complex emulsifier penetrant systems. Various sensitivities are selected based on the product and customer requirements. The most important limits for using PT are a temperature below 5 °C and bad weather. Surfaces for testing should be very clean. We are experts in setting up specific testing programs for our clients.
