ActiveNon-destructive testing—Ultrasonic guided-wave testing—Part 2:Test method based on magnetostrictive transduction
无损检测 超声导波检测 第2部分：磁致伸缩法
Application Summary AI generated
This standard specifies the test method for ultrasonic guided-wave testing using magnetostrictive transduction, detailing procedures for detecting corrosion, cracks, and wall thinning in ferromagnetic pipes and tubes. It is applied in industries such as petrochemical, power generation, and pipeline transportation for in-service inspection of above-ground and buried pipelines. The method is particularly useful for rapid, long-range screening of pipe integrity without removing insulation or coatings.
