Factor Analysis,Supervision and Control for Ultrasonic Flaw Test

SHI Feng,XIE Jian-ping,LIANG Ya-dong(Safety Environment & Technology Supervision Research Institute, China Petro Sichuan & Chongqing Quality Supervising Station,Chongqing 400021,P.R.China)  
Since oil pipeline works under the bad environment and is possible to generate leakage and explosion,the non-destructive testing of oil pipeline weld is an important topic for oil pipeline.The principle of ultrasonic flaw testing technology not only is described,but also the cause of the quality of field ultrasonic flaw testing is analyzed in detail.Compared to other non-destructive testing technologies,the ultrasonic flaw testing reduces the cost and the detection time,and duly detects the inner flaw of the weld.Finally,one example is analyzed,and the corresponding measures are presented to supervise the ultrasonic flaw testing.
