Radiographic testing (RT) is one of the most essential volumetric non-destructive testing (NDT) methods used in industry. It allows the detection of internal flaws using either X-rays or gamma radiation, generated from a tube or isotopes such as Iridium-192, Selenium-75, or Cobalt-60. RT techniques include film radiography, computed radiography (CR), direct radiography (DR), real-time radiography (RTR), and computed tomography (CT). These methods can penetrate materials of varying densities to assess weld quality, identify corrosion or erosion, evaluate castings for defects or foreign objects, and detect damage in composite materials—without compromising the component.
Applus+ is a world-leading authority in radiographic testing services, offering reliable inspection techniques to detect imperfections in materials across industrial operations. RT supports the evaluation of production assets and equipment in demanding sectors like oil and gas, where detecting issues early is vital for safety and efficiency.
Applus+ also leads in advanced technology, with dedicated R&D laboratories, global reach, and collaboration with industry experts. We have developed the proprietary Rayscan System, a real-time digital radiographic inspection tool capable of scanning a full production pipe in a single rotation. This technology also enables Rayscan Tankscan, which inspects LNG storage-tank welds in one scan, producing high-quality images while reducing inspection time.
Radiographic testing is widely applied in both new construction and in-service asset evaluation. Whether using film or digital techniques, RT verifies weld quality and helps profile piping systems to detect internal flaws, corrosion under insulation (CUI), flow-accelerated corrosion (FAC), or remaining wall thickness.
Applus+ provides radiographic inspection services across multiple sectors and applications, including:
