Liquid Penetrant Testing (PT)

Liquid Penetrant Testing in India

Industrial and environmental inspection, vendor inspection, technical assistance, non-destructive testing NDT and technical staffing for all type of industries. Multidisciplinary laboratories. Testing and engineering for product development. Conformity testing and product certification. Liquid penetrant testing LPT is one of the most widely used non-destructive testing methods. LPT is based on capillarity or capillary attraction, where a liquid is able to flow into narrow spaces without the assistance of — or even in opposition to — external forces such as gravity. The materials processes and procedures used in liquid penetrant testing are designed to make the results of this capillary action visible and capable of interpretation.

Liquid Penetrant Testing

With a wide variety of penetrant materials and a custom made fluorescent penetrant inspection system, RNDT personnel can provide both field and lab, high volume processing of many different parts with both fluorescent and visible penetrants. The test object or material is first cleaned and then coated with a visible or fluorescent dye solution. After a pre-selected time interval dwell time , the excess dye is removed from the surface, and then a developer is applied. The developer acts like a blotter and draws penetrant out of imperfections which are open to the surface.
