As pipeline segments are safety-relevant parts with demanding international quality standards it is required to perform a comprehensive X-ray inspection of the welding lines after production. This paper will present leading quality standards like ISO-17636-2 and API 5L and will highlight their practical relevance.

A main focus will be the different quality metrics like spatial resolution (SRb), Signal-to-Noise Ratio (SNR), Contrast Sensitivity (CS) and long-term stability evaluation of Digital Detector Arrays (DDA). Furthermore, it will introduce different set-ups to inspect the welding lines created by different techniques (spiral, longitudinal and circumferential). An outlook will present automation techniques to increase throughput, while ensuring highest process safety. It will provide responsible NDT managers with comprehensive tools to calculate Return on Investment (ROI) of finances aspects in Digital Radiography (DR) and to ensure a smooth transition from traditional film techniques.
