The ERW pipe flaw detection method mainly includes magnetic testing, ultrasonic testing, and visual inspection. Among them, magnetic testing is the most commonly used method, which can detect internal and external flaws of the pipe through magnetic induction and magnetic flux measurement. Ultrasonic testing uses high-frequency ultrasonic waves to penetrate the pipe to detect internal defects. Visual inspection refers to using traditional inspection methods to detect defects by visually observing the pipe surface. However, the accuracy and sensitivity of these methods are different, and different methods are used for different types of flaws. Generally, the combination of various methods can achieve better detection results.
