DR数字平板检测技术在直缝埋弧焊管生产中的应用

为了更加快速、有效地检测油气输送焊管的焊缝缺陷,提出了DR数字平板检测技术,并介绍了该检测系统的组成和检测标准,将该系统的成像效果与传统的图像增强器成像系统进行了对比,并进行了实际应用。结果表明,DR数字平板成像检测技术的静、动态灵敏度均高于图像增强器成像系统,并且超出国内外相关标准的要求,动态检测图像清晰,有利于焊缝中细小缺陷的检出,是快速、高效地进行直缝埋弧焊管焊缝检测的有效手段。

Application of DR Digital Plate Detection Technology in SAWL Pipe Production

In order to more quickly and effectively detect oil and gas transportation pipe weld defect, it put forward the DR digital plate detection technology, and introduced the composition of this detection system and test standard. The imaging effect of this system and the traditional image intensifier imaging system were compared, and the two kinds of detection technologies were conducted practical application. The results indicated that the dynamic and static sensitivity of DR digital plate detection technology both are higher than that of image intensifier imaging system, and exceed the requirements of related standards at home and abroad. The image of dynamic detection is clear, it is conducive to the detection of small defects in weld, which is an effective way to quickly and efficiently detect SAWL pipe weld.
