【摘要】："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。
[Abstract]:"Non-stop electromagnetic Nondestructive testing Technology and its Application for large pressure equipment" is a worldwide problem which is badly needed for the long period operation of large equipment. With the support of a series of national scientific research projects and the joint efforts of more than 60 scientific and technical personnel from more than 10 units, the research has revealed the response law of corrosion and stress damage of common materials used in large pressure equipment under different electromagnetic excitations. Three kinds of electromagnetic testing instruments and systems with independent intellectual property rights are developed, and four electromagnetic detection and result evaluation methods suitable for corrosion and stress damage of different materials are put forward, and the corresponding detection technical standard system is established. Large pressure equipment with paint layer, no removal or partial removal of insulation layer, etc., is tested without stopping, and the bottleneck technical problem that has plagued the government and enterprises for a long time has been solved. This paper summarizes the background, achievement and application of the project based on the National Science and Technology Award recommendation of the National Science and Technology Progress Award of 2015.
