Techniques Of Non Destructive Testing

By | March 10, 2017

Non-destructive testing (NDT) is the process of analysing assets in a manner which doesn't degrade or destroy them in any way. Principles such as ultrasonics, electromagnetics and acoustics (among others) are used in order to gain information about the asset, without damage. 

The assets inspected and nature of the inspection can fluctuate greatly, with unique applications arising commonly. Typically assets, however, include items such as pipelines, storage tanks, boiler tubes, condensers, heat exchangers, distillation columns, all the way through to small aircraft parts, and structural welds.

Ultrasonics Testing – Ultrasonics is a simple technique employed, providing certain information, with great precision and accuracy. Ultrasonics can be used to control the thickness of an asset with ease, and giving remaining wall thickness. This is a very popular technique, often utilised because of its ability to determine corrosion rates, provide accurate data and the speed of inspection.

Magnetic Particle Inspection (MPI) – This is a great technique for use on welds, or other areas answering may be of concern. MPI uses high contrast paint, in conjunction with magnetic particles in order to look for very fine cracking and other defects. MPI provides a more hi-tech, modern alternative to more outdated techniques such as vacuum box inspection.
