摘要:
简要介绍了小直径薄壁焊管的特点及检测存在难点。对小直径薄壁焊管的超声和射线检测进行了重点分析,总结了超声和射线检测时各重点参数的选择原则。最后对两种检测方法进行了比较。结果表明,射线检测对体积型缺陷的检出率较高,而超声检测对面积性缺陷的检出率较高;射线检测很难精确确定缺陷在工件厚度方向的位置和尺寸,而超声检测不存在此问题;射线检测比超声检测更适宜薄壁工件的检测。
Abstract:
In this article, it briefly introduced the characteristics and the testing difficulties of the small diameter thin wall thickness welded pipe, then analyzed two detection methods, the ultrasonic and radiographic detection, and summarized the choice of the key parameters for ultrasonic and radiographic detection. Finally, two kinds of detection methods are compared; the results indicated that the detection rate of radiographic test is higher for volume type defect, and the detection rate of ultrasonic test is higher for area defects; it is very difficult to accurately determine the position and size of defects in workpiece thickness direction for radiographic detection, this problem did not exist in ultrasonic test. Radiographic detection is more suitable for thin wall thickness workpiece.
