本文给出了超声波智能清管器在PrudhoeBay油田对三条管线在线检测的结果。超声波（简称UT）清管器所指示的管道腐蚀程度导管道实际腐蚀程度（由手动X射线技术和手动超声波技术测量）进行了比较，发现超声波智能清管器检测的结果与管道实际腐蚀情况严重不符，在所选择的100个检测点中，UT清管器均很大程度地夸大了管道的内腐蚀程度。
This paper presents the results of on-line ultrasonic inspection of three pipelines in the Prudhoe Bay oil field. The degree of corrosion of the pipe indicated by the ultrasonic catheter (UT) pig was compared with the actual corrosion of the pipe (measured by manual X-ray technique and manual ultrasonic technique) and found that the result of the ultrasonic intelligent pig inspection was seriously corrosive to the actual corrosion of the pipe Does not match, in the selected 100 test points, UT pigs have greatly exaggerated the degree of internal corrosion of the pipeline.
