| Abstract: | Pipeline corrosion accidents are becoming increasingly frequent in recent years,such as leakage,rupture and perforation.Therefore,online nondestructive testing is of great significance to maintain integrity of pipeline structure.At present,electromagnetic acoustic transducer and pulsed eddy current testing are the most widely used technologies.However,they still have weaknesses such as low test efficiency,low test coverage and limited application.In contrast,magnetostrictive ultrasonic guide wave detection has excellence performance in all these aspects.Its principle and main influencing factors were introduced.Online detections were carried out on outlet pipeline of absorption tower and inlet pipeline of high-pressure air cooler.The facts proved that the technology has good feasibility and practicability in pipeline corrosion detection. |
