Abstract
Non-contact Magnetic Tomography Method(MTM) carries out in semiautomatic mode the non-destructive testing of pipeline metal technical condition and its insulating coating condition in 100% volume. The danger of faulty sections is evaluated depending on the degree of stress concentration in anomaly area according to RD 102-008-2009 “Directions for diagnostics of pipeline technical condition by non-contact magneto metric method”. Combining the Xinjiang oilfield, pipeline company field application, there is a detail analysis about the standard contents involving defect location, defect recognition, safe working pressure, dangerous degree, repair advice, test process, data analysis, results evaluation, and on-site check program and so on. And the MTM technical advantages and characteristics are clarified, for further promotion application provides conditions.
