摘　　要：大型锅炉系统内高温管道易产生疲劳、蠕变等损伤模式,找到合适的无损检测方法对高温管道损伤进行检测,是目前在役检测技术发展的难点。文中从大型锅炉系统内高温管道损伤出发,介绍声学、电磁学等方法中具有可行性的检测方法及其研究进展。研究发现,这些新型检测技术对于锅炉高温管道的损伤检测都有各自的优势,但由于其各自的局限性,可以考虑多种检测技术组合的检测方案,以保证在检验周期内管道的长周期安全运行。High-temperature pipeline in large-scale boiler system is easily affected by fatigue,creep and other damage modes.Finding suitable non-destructive testing methods to detect high-temperature pipeline damage is the current difficulty in the development of in-service detection technology.This paper started from the damage of high-temperature pipeline in large-scale boiler system,the feasible detection methods and their research progress in acoustics and electromagnetics were introduced.The study finds that these new detection technologies have their own advantages for boiler high-temperature pipeline damage detection.However,due to their respective limitations,a combination of detection technologies can be considered to ensure the safe operation of the pipeline in the long period of inspection cycle.
