Automatic ultrasonic inspection of steel catenary riser welds
摘 要
在对钢悬链线立管(SCR)焊缝进行自动超声检测(AUT)的过程中,要求AUT具有可靠的检测能力和较高的检测精度。通过修正AUT缺陷评定方法,验证了AUT焊缝缺陷评定结果与金相检验结果的可靠性。结果表明,修正后的AUT评定结果与缺陷实际尺寸具有良好的一致性,为基于工程临界分析(ECA)验收标准的SCR管线的安装工程应用提供了借鉴。
Abstract
During automatic ultrasonic testing (AUT) of steel catenary riser (SCR) welds, it is required that the AUT technology should have reliable detection ability and high detection accuracy. The reliability of the AUT weld defect evaluation results and the metallographic examination results was verified by the modified AUT defect evaluation method. The results show that the modified AUT evaluation results are in good agreement with the actual size of the defect, which provides a reference for the installation engineering application of SCR pipeline based on the engineering critical analysis (ECA) acceptance standard.
