Corrosion of Metallic and Nonmetallic Piping for Bleach Plan D Stage Filtrate (14013)
By David C. Crowe and Arthur H. Tuthill, reprinted from Proceedings of the TAPPI Engineering Conference, Seattle, Sep 25, 1990. The condition of six-inch diameter by two-foot long spools of PVDF- and PTFE-lined steel, welded titanium, Alloy G, and AISI type 31 7L steel after approximately 10 years' exposure in a D stage filtrate line is reported. Weld- and heat-affected zone performances are described. This report is part of TAPPI Metals Subcommittee CA4924 Bleach Plant Pipe Test Program.
