On the development of national standards for magnetic and eddy-current nondestructive inspection of steel pipes

Comparative analysis of the technical level of different nondestructive-testing methods (ultrasonic, magnetic, and eddy-current) used in the production of seamless and HFC welded pipes is performed. To increase the quality of pipes produced for operation under elevated pressure and to unify nondestructive-testing methods and facilities used, standards for magnetic and eddy-current inspection are developed in accordance with the stated foreign acceptance levels.
