Ultrasound offers significant advantages over radiography

Advanced nondestructive technologies (NDT), such as time-of-flight diffraction (TOFD), phased-array (PA) and guided waves (GW), are utilized in many different ways to assure the integrity of pipelines at different stages of their lifecycle. In addition, these techniques have shown to be reliable replacements for radiographic testing (RT) in ensuring pipeline integrity.



In manufacturing plants, in-line automated ultrasonic phased array systems are used to perform full-body inspection of seamless and welded pipes with very high throughput. In the field, during pipeline construction, automated ultrasonic techniques are used to inspect girth welds with high accuracy, offering significant advantages over radiography.



During maintenance, when pipes are accessible, semi-automated and portable phased array ultrasonic testing is used to accurately map corrosion degradation. Phased array technology also features comprehensive imagery that facilitates results analysis and interpretation, as well as electronic data archiving for easy traceability. When pipes are not accessible, long-range guided wave ultrasonic testing is capable of inspecting long distances of pipe; this is considered a very useful and efficient screening tool for detecting anomalies.



You should attend whether you are a novice in NDT or an experienced NDT inspector and want to know more about the replacement of radiography with advanced UT for pipeline inspection. Pipeline owners, operators and contractors would also benefit from this webinar to improve their pipeline integrity program. Please register for this free, valuable, and informative webinar.
