The application of electromagnetic ultrasonic guided wave detection technology in cylindrical pipe detection was studied and analyzed.The basic theoretical relations of axial guided wave are analyzed and deduced. The dispersion characteristics of axial guided wave are analyzed emphatically. The non-dispersion characteristics of torsional guided wave are of great significance in detection.The basic principle and design method of axial guided wave excited by electromagnetic ultrasonic sensor in recent years are discussed emphatically.The existing problems and development direction of pipeline shaft guided wave nondestructive testing technology are put forward.
