Stainless steel has been used extensively for potable water since the mid-1960s in desalination plants for handling product water; in potable water treatment plants for gravity filtration and piping; in Tokyo, Japan, for small-diameter household connection piping; and in New York City for large-diameter risers and other piping. The most familiar use of stainless steel is for drinking fountains. Background information and general data are given on types 304 (UNS S30400) and 316 (S31600) stainless steel, and their current use in potable water applications is reported. The behavior of stainless steel used with raw, chlorinated, and finished water as well as of piping buried in soil is reviewed. Postfabrication cleanup and maintenance of exterior appearance and cleanliness are also reviewed. Guidelines for procurement and successful use are suggested. Includes 11 references, tables, figures.
