双壁单影透射法及辅助工装在管道探伤中的应用

Double-wall single-image method and its application in pipework crack detection

对双壁单影探伤法进行了简单介绍,并设计了一种用于双壁单影法对供热管道焊缝进行探伤时的新型辅助设备。实践证明,该设备操作简单,造价低廉,应用该设备可明显提高工作效率,确保工程质量和设备的安全性。

The detection method of double-wall single-image radiography was introduced. A kind of secondary device of crack detectionwas designed when the welding lines of pipelines were tested by method of doublewall single-image radiography. The results showed that this simple work device with low price could greatly improve the efficiency, quality and safety.
