“大型承压设备不停机电磁无损检测技术及应用”针对大型成套装置长周期运行急需的不停机检测技术这一世界性难题。在国家系列科研项目的支持下,在10多家单位、60多名科技人员的共同努力下,历时10多年,研究揭示了大型承压设备常用材料腐蚀和应力损伤在不同电磁激励下的响应规律,开发了具有自主知识产权的三种电磁检测仪器与系统,提出了适用于不同材料腐蚀与应力损伤的四种电磁检测和结果评价方法,研究建立了相应的检测技术标准体系,实现了带油漆层、不拆或局部拆除保温层等的大型承压设备不停机检测,解决了长期困扰政府和企业的瓶颈性技术难题。该成果获得2015年度国家科学技术进步二等奖,本文以该成果的“国家科学技术奖励推荐书”为基础,综述了项目背景、成果及其应用情况。
“Large-scale pressure equipment non-stop electromagnetic non-destructive testing technology and application ” for large-scale long-cycle operation of the device is needed for non-stop detection technology, a worldwide problem. With the support of a series of national scientific research projects, with the joint efforts of more than 10 units and over 60 scientific and technical personnel, it lasted more than 10 years and the research revealed the response rules of corrosion and stress damage of common materials for large pressure equipment under different electromagnetic excitation , Developed with three kinds of independent intellectual property rights of electromagnetic detection instruments and systems, proposed for different materials corrosion and stress damage of four kinds of electromagnetic detection and evaluation of results, the establishment of the appropriate testing standards system to achieve with the paint Layer, without demolition or partial removal of the insulation layer and other large pressure equipment does not stop testing, to solve the bottleneck of the long-standing government and business problems. The achievement was awarded the second prize of 2015 National Science and Technology Progress Award. Based on the “National Science and Technology Award Recommendation” of this achievement, this article reviews the background, achievements and application of the project.
