摘　　要：在大港—济南—枣庄成品油管道施工中,残存于管道内壁焊道上的焊接飞溅严重影响X射线胶片的质量和缺陷的评定。为此,自制了简易清管器。实践证明,在管口组对焊接前将这种简易清管器放在焊口处,能大大减少飞溅在管道底部的沉积,提高X射线胶片的质量。In the construction of the Dagang—Jinan—Zaozhuang products pipeline, welding spatter remaining on the internal wall of the pipeline affects severely the recording quality of X-ray film and the defects assessment. Therefore, a simple self-made pig was applied to clean the spatter. Practice proved that putting this device at the position of weld before pipe butt welding would remarkably decrease spatter accumulation at the bottom of the pipe and thus increase the recording quality of X-ray film.
