Comparison and Analysis on NDT Standards of Gas Transmission Pipeline Project
In allusion to the different requirements proposed in NDT standards on butt welds in construction of pipeline project, regulations in relative NDT acceptance standard and qualified grade in GB50251 and GB50396 are introduced, and regulations in relative NDT standard and quality grade in GB/T 3323 and SY/T 4109 are compared. Reference commendations on revision of the standards and codes are given.
