摘要:

介绍了国内外核电厂用高密度聚乙烯(PE-HD)管材的标准规范及工程应用情况。虽然PE-HD材料在核3级管道应用的案例较少,但基于PE-HD管材优异的耐腐蚀性能,其应用前景广阔;在核电工程应用中标准规范有着重要作用,美国已建立了ASME规范,法国建立了RCC-M规范,我国目前参考ASME规范开展工作,同时也开始编写相关国家规范;为保证核电厂冷却用水的可靠性和机组的安全稳定运行,在工程应用中,应从设计、制造、熔接、无损检测、在役监督、老化管理等方面进行考虑。

Abstract:

This paper introduces the standard specification and engineering application of high-density polyethylene (PE-HD) tubes for nuclear power plants at home and abroad. Although there are few cases of PE-HD material being used in nuclear grade 3 pipeline, the application prospect of PE-HD material is broad due to its excellent corrosion resistance. Standards and specifications play an important role in the application of nuclear power engineering. The United States has established the ASME code and France has established the RCC-M code. At present, China carries out work with reference to the ASME code and also begins to write relevant national codes.In order to ensure the reliability of cooling water for nuclear power plants and the safe and stable operation of the units, the design, manufacturing, welding, nondestructive testing, in-service supervision, aging management and other aspects should be considered in engineering application

Key words: nuclear power plant, high-density polyethylene, nuclear class 3 piping, fusing, ASME code
