Non-Destructive Testing


Ultrasonic testing (UT) is a non-destructive testing technique that utilizes high-frequency sound waves to detect imperfections in metal materials, as well as changes in properties within the materials that could cause problems or failure of the component being tested.

Radiography testing (RT) is a non-destructive testing technique that utilizes x-rays or radioactive isotopes to test metal materials -- much the same way that doctors analyze “x-ray images” taken of their patients.

Magnetic particle testing (MT) is a non-destructive testing technique utilized to detect defects (such as cracks) at or near the surface in metals. This technique utilizes a magnetic field, combined with the application of fine magnetic particles (similar to iron shavings) to reveal defects.

Liquid penetrant testing (LT) is a non-destructive testing technique where the material being tested is coated with a liquid dye solution (sometimes fluorescent dye is used). The dye is then removed and a developer is applied – which acts to “draw” the dye out of any defects present, allowing the defect to be seen easily.

Non-destructive testing techniques are particularly useful in the industrial sector as a cost-effective way to evaluate the integrity of metal materials and equipment. In many instances, older materials and bonding methods are still in active use – particularly in the oil & gas industry. With non-destructive testing, companies are able to help ensure that these materials can continue to be utilized safely – reducing the likelihood of structural failure and potential accidents. As such, non-destructive testing often plays a critical role in both quality control and safety for many industrial businesses.
