Three propylene spherical tanks which have both the same manufacturing parameters and conditions have been assessed based on risk assessment and non-destructive testing technology. One of the spherical tanks is stopped for comprehensive inspection, and the result of inspection verifies the reliability of risk assessment, which is applied to other two unopened propylene spherical tanks. Meanwhile, in order to make overall inspection level meet the requirements of the risk assessment and so reduce spherical tanks assessing risk, ultrasonic diffraction detection (TOFD) with high detection rate and fluorescent magnetic surface detection technology are adopted to ensure comprehensive test meeting the risk assessment requirements, which can also provide significant guidance for future complete equipment inspection.
