X-ray inspection is an established non-destructive testing (NDT) method for the inspection of pipelines, valves and pressure vessels using film-based methods. DT’s digital X-ray imaging solutions provide immediate high quality imaging without the use of chemicals thus reducing the time and cost.
In addition to 2D X-ray, DT is a leading supplier of advanced X-ray imaging solutions for precision 3D computed tomography (CT) applications. 3D computed tomography enables the internal structure of objects to be examined rapidly and non-destructively. CT may be used to inspect castings to identify defects including fractures, porosities and inclusions. Specialized CT systems may be used to inspect pipelines providing detailed cross-sectional images for verification of integrity and flow assurance.
Take as an example weld inspection, identification of cracks, measurement of pipeline wall thickness and flow assurance, diagnosis of flow abnormalities and location of blockages.
