| Abstract: | It briefly introduced defects type of drill pipe failure,the commonly used ultrasonic inspection method for drill pipe at home and abroad and the current inspection status on-site.Based on the magnetic flux leakage inspection system working principle,it can effectively find out the defects of drill pipe body to reduce the accidents.In order to further validate the magnetic flux leakage inspection system,using portable magnetic flux leakage inspection device,which is produced by some America company,to detect drill pipe sample with OD 127 mm(5 in)and WT 9.19 mm.The result showed that this system can quickly and reliably find some defects,such as φ1.6 mm hole,N5 transverse inside and outside notch,5% loss of wall thickness etc.. |
