高密度聚乙烯管在核设备中应用的关键技术挑战
Key Technical Challenges of High Density Polyethylene (HDPE)Pipe in Nuclear Equipment
摘要
Abstract
China plans to build new nuclear power plants at a rate of six to eight per year after the year of 2016,and more than 110 nuclear power plants will be operated by the year of 2030.Since there are many water pipes in nuclear power plants,the selected pipe material plays a very important rule for the development of Chinese nuclear power plants.Compared with metallic pipes,high density polyethylene (HDPE)pipes have the advantages of abrasion resistance,earthquake resistance,easy installation,and low cost.This paper reviews the mechanical performance of welded joint and its influence factors,effects of defectson the structural integrity,defect detection techniques and life prediction methods,and the quality of Chinese HDPE resin.Finally,based on the ASME HDPE roadmap,the key problems that need to be solved and the corresponding solutions are listed to attract the attention from industry,government departments,and other scientific and technological persons,promote the development of standards and codes for HDPE pipes as soon as possible,and accelerate the development of HDPE pipe industry and its safe use in nuclear service.关键词
