平板DR数字成像技术在焊管行业中的应用

Application of Flat Panel Digital Radiography Imaging Technology in Welded Pipe Industry

介绍了DR数字成像技术的工作原理及其在焊管行业检测中的应用。在灵敏度检测、图像分辨率、剩磁影响和辐射剂量等方面与传统的X射线工业电视的检测效果进行了比较分析。结果表明,DR数字成像技术具有检测灵敏度和检测效率较高、劳动强度小、辐射剂量小等优点,保证了焊缝质量,大大降低了管线的事故发生率,可以替代传统X射线工业电视检测技术在焊管行业的应用。

In this article, it introduced the working principle of digital radiography（DR） imaging technology and its application in welded pipe industry. Compared with the detection effect of traditional X-ray industrial TV from sensitivity detection, image resolution, residual magnetization, radiation dose etc. The result showed that the flat panel DR imaging technology is with some advantages, such as high sensitivity of detection, high efficiency, low labour tension, little doses of radiation and so on. It ensures the weld quality, greatly reduces the accident rate of pipeline, and can replace X-ray industrial TV detecting technology. At present, this technology is widely applied in welded pipe industry.
