Nonmetallics. Their Performance in the Desalination Environment,

摘要

This report describes the testing of nonmetallic materials of construction and their performance in a desalting environment at the OSW Materials Test Center at Freeport,Texas. Of seventy-three paint and coating systems tested in treated sea water,sixty were considered satisfactory for desalination plant service at 110F;only eighteen systems were rated as adequate at 250F. Baked phenolic or fluidized bed-polyphenylene sulfide types should be considered for high temperature operations. Nineteen fiber reinforced plastic (FRP) laminate systems,thirteen thermoplastic types and fifteen commercial FRP piping systems were evaluated at regular intervals over a total exposure period of fifteen months. Polysulfone was an outstanding thermoplastic in 250F sea water. Prekrete (Trade Name) G-8was the only corrosion resistant cement found suitable for use in 250F sea water.
