SHIPBOARD EVALUATION OF GRP SOIL DRAIN PIPING ON USS SAIPAN (LHA-2)
Glass-reinforced plastic (GRP) piping was evaluated in the soil drain system of USS SAIPAN (LHA-2) to determine its ability to reduce the incidence of scale buildup. Although scale buildup rates for seawater serviced GRP and copper-nickel soil drains were found to be high, scale formed at a rate of 2.5 times slower in GRP pipe than in comparably used copper-nickel soil drains. Review of past studies in conjunction with practices observed during this evaluation revealed that current mechanical scale removal techniques used for copper-nickel pipe cannot be successfully applied to GRP pipe; however, commercial descaling agents can be used for GRP if the total collection system volume is not excessively large.
