| Abstract: | The scope of the application of ultrasound guided wave detection had a close relationship with guided wave＇ s excited principle. According to the characteristics of high - temperature pipelines, magnetostrictive effect was adopted to the detection of ultrasonic wave of high temperature pipe. The application of MsS3030 was introduced, 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 demand of inspection of in - service high - temperature pipe, besides find the defects effectively, and had wide prospect. |
