Abstract

Digital radiographic imaging technology applied in metal wall thickness measurement mainly addresses the non-contact thickness measurement for online inspection of high-temperature operating equipment and devices. This technology utilizes the penetrating and attenuation principles of rays, combined with the precise capture of digital detectors and image software analysis and processing, to achieve estimation and measurement of changes in metal wall thickness. The study reveals the unique advantages of digital radiographic imaging in metal wall thickness measurement, facilitating the detection of thickness changes caused by corrosion and thinning, thus providing reliable data support for the safety assessment and maintenance decisions of metal structures.

Keywords
