Stephen Petit, on behalf of Zetec, details how the latest NDT technologies deliver more accurate pipeline inspections without requiring the removal of coatings. Inspecting pipelines for material thickness, defects, and weld integrity is one of the most challenging - and common - types of non-destructive testing(NDT) applications in the oil and gas industry. NDT techniques range from simple manual and visual tests to sophisticated technologies that detect and measure surface and sub-surface flaws, porosity, variations in metallurgical structure, corrosion, and a range of other discontinuities in exposed pipelines without having to damage or destroy materials. While NDT inspections can help pipeline owners 'see' what's going on with their assets, coatings can complicate the process.
