摘　　要：在介绍了几种海水淡化装置常用双相不锈钢的特性的基础上,分别针对双相不锈钢在低温多效海水淡化、反渗透海水淡化、多级闪蒸海水淡化装置以及相关储罐和管线上的应用现状和发展趋势进行了阐述,并强调了双相不锈钢在降低海水淡化成本、提高海水淡化装置寿命以及实现装置国产化等方面的巨大潜力。In this paper, on the basis of introducing the characteristics of some duplexstainless steel grades commonly used on seawater desalination equipment, the current applica原tion status and development trend of duplex stainless steel in low temperature multi-effectseawater desalination, reverse osmosis desalination, multi-stage flash water desalination plantand related storage tanks and pipelines are elaborated. The great potential of duplex stainlesssteel in reducing desalination cost, improving the service life of desalination plant and achiev原ing localization of core device are also stressed.
