| Abstract: | The scope of the application of Ultrasound guided wave detection has a close relationship with guided wave＇ s excited principle, according to the characteristics of high-temperature pipelines, maguetostrictive effect is chosen as excited principle. It is also introduced the application of MsS3030 , based on magnetostrictive effect, in in-service testing of high-temperature pipe, and testified the result reliability by detection of the thickness on site. According to the final result, this method, based on magnetostrictive effect, could meet the demands of inspection of in-service high-temperature pipe, besides the defects can be found effectively. It has wide prospect. |
