Abstract: The principle of Tmode magnetostrictive guided wave technique for the inspection of defect in pipe was introduced. The artificial defects including circumferential notches and drilled holes were inspected using a magnetostrictive guided wave inspection system MsSR3030. The processes of data acquirement and analysis were given as well as data report of inspection. The practice of the pipe inservice inspection was also introduced. Testing results validated the high accuracy and shortcut of Tmode magnetostrictive guided wave inspection for pipes.
