Chart Analysis on Flaws of Steel Tubes Tested by ROT250 Ultrasonic Flaw Detector

CHEN E,XIE Xiao-hui (Seamless Tube Plant of Steel Union Co.Ltd.of Baotou Steel(Group) Corp.,Baotou 014010,Nei Monggol, China)  
In the paper,it is introduced that the operating principles of ROT250 ultrasonic flaw detector made by NU-TRONIK Company of Germany.Especially,the ultrasonic characteristic curves of different flaws for steel tubes tested by ultrasonic are enumerated,which has had a good effect and provided some valuable experiences for ultrasonic examination of steel tubes in future.
