The principle of Tmode magnetostrictive guided wave technique for the inspection of defects in pipes is intro duced in this paper. Studied here are the magnetostrietive guided wave technology detection sensitivity and accuracy of the pipe line defect. The experimental results show that the testing technology is of high sensitivity and accuracy. On this basis, the testing technology for pipelines in service is applied for online detection, the data analysis results and the reliable sensitivity of defects of the pipes are given by means of the magnetostrictive guided wave technology in different environments. Testing results validate the high reliability and shortcut of Tmode magnetostrictive guided wave inspection for pipes.
