英文摘要：

Addressing the increasingly huge demand for hi-speed flux leakage steel pipe detecting equipment, the coauthors, based on the working principle and method for such equipment, point out and analyze the critical techniques related to the hi-speed flux leakage detection process. With the critical techniques as identified, the first hi-speed flux leakage steel pipe detection system in the country has been developed, which is operating with the pipe rotating spirally, and at a detecting speed up to 2.8 m/s, having resulted in inspection target values conforming to the most stringent NDT requirements as specified under applicable API specification, and brought about satisfactory operation effectiveness.
