Mechanical deformation of the pipeline can occur in a number of ways, during initial construction, following modification, and through third-party excavation work.
Undetected, the resulting flaws can lead to serious damage, to pipeline coatings and to cracks and corrosion. Conventional inline geometry measurement is based on the use of mechanical calipers which has a number of potential issues associated with lift-off, tool damage and speed effects.
Using ultrasonic technology ensures precise direct measurement of dents with depth resolution down to 0.1 mm (0.004 in). Multiple datasets are gathered in a single inspection without time-consuming calibration.
Combined inspections enhance the identification of combined defects as the data is fully aligned. Data analysis now utilizes this combined data with improved identification of corrosion associated with dents.
Our Ultrasonic Tools
Evo Series 1.0 delivers the most accurate and reliable ultrasonic inline inspection available today. Combining a corrosion or crack assessment with ultrasonic based geometry measurement enables a comprehensive inspection in a single run.
Accurate pipe geometry measurement and detection of dents is essential for pipeline integrity management. Using ultrasonic technology ensures precise direct measurement of dents with depth resolution down to 0.1 mm (0.004 in).Read More About It

Thanks to the NDT Global Engineering 'A Team', and work by the Sunbury Flowlines team, a plan was conceived to put the pig on a diet.
NDT showed a profound expertise and reliability. NDT impressed with their quality of service provided through their personnel as well as the outstanding performance of the inspection tool providing excellent data. The final reports were delivered in due time and with excellent quality. Based on this experience and the good business relationship, we are happy to recommend NDT Global for the inline inspection services.
All work was performed in accordance with Statoil's specifications and to complete satisfaction. The data results were precise and reliable and perfectly reflected the pipeline conditions. During the last years NDT has been an excellent cooperation partner for us in every respect. Precision and reliability are the cornerstones of their work.
