​Non-Destructive Testing: Liquid Penetrant Testing Services

Liquid penetrant testing (PT) is used by Geo-Per International as a non-destructive testing technique designed to detect surface defects and issues in plastics, metals, ceramic and other solid, non-porous industrial objects.
​
Our CWI are very familiar with the process of liquid penetrant testing, having conducted it for a wide range of industries and customers.
How does liquid penetrant testing work?

The object in question must first be completely cleaned (often this is done through a process called phase cleaning). All contaminants such as oil, grease, dirt must be removed from the item before testing can begin. Once the item is cleaned, a penetrant or dye is applied to the surface of the object and left to soak for around 15 minutes, after which a dry chalk is applied. This chalk will react with any penetrant to reveal abnormalities and flaws, making them visible.

Geo-Per International offers liquid penetrant testing as a viable non-destructive testing type that is great for revealing surface level discontinuities that need to be found during a welding inspection.

Liquid penetrant testing is an inexpensive NDT technique that will help you to save money and keep your quality control standards high at the same time.

As a welding inspection company in Houston, Geo-Per International has performed liquid penetrant testing for numerous oil and gas companies, shipping companies and other industrial interests.
