| Popis: | The comparatively new technology of computed radiography (CR) for NDT imaging has a number of advantages over traditional film-based radiography, including reduced exposure times and greater dynamic range. In addition, it does not require facilities for the developmentof radiographic film, which can be difficult to install and maintain given the often restricted deck facilities space in an offshore environment. However, the technology associated with CR is substantially more complex than film and, in the absence of any internationally recognised standards for in-service radiographic inspection, the quality of the resulting CR images can be variable. To improve the quality control of this form of inspection, the HOIS JIP has developed a recommended practice covering CR for the in-service inspection of pipes for wall loss type flaws (corrosion, erosion). This project involved a series of experimental trials to first develop and then validate the recommendations, and also quantitatively compare the characteristics of different commercially available CR systems. The results of the CR trials undertaken during this project and the main recommendations of the recommended practice are described. |
