Abstract
Digital radiography (DR) is a powerful technique that can be used in non-destructive testing for identification of internal or external defects and corrosion mapping. New generation of digital flat panel detectors become more and more competitive to film detectors, however the transition from film to digital radiography is not always the best choice for every NDT organization especially from the point of view of investments. The paper introduces the application of digital corrosive radiography mapping on gas pipelines using a portable flat panel detector. The experimental part is focused on determining the residual thickness of the pipelines in service.
Highlights
During the past two decades, digital radiography has supplanted screen-film radiography in many industrial applications
Digital radiography flat-panel systems with integrated readout mechanisms were introduced in the market by the end of the 1990s
Residual thickness was measured by mechanical gauge and digital radiography
Summary
During the past two decades, digital radiography has supplanted screen-film radiography in many industrial applications. Manufacturers provide a variety of digital imaging solutions based on various detector and readout technologies. Digital detectors allow implementation of a fully digital picture archiving and communication system, in which images are stored digitally and are available anytime. One of them is portable digital radiography system. Portable digital radiography provides many benefits to users. DR systems enable reduction of working time and costs while enlarging the profits of NDT service providers. This modern DR system can be used to identify defects and weld materials and to corrosion mapping on gas pipelines in services [1]
