This presentation includes the discussion of ways to identify corrosive conditions and the means to protect ductile iron pipe in these environments. It also outlines the development and performance of polyethylene encasement as the most commonly recommended corrosion protection system for Ductile Iron pipe. Also presented in this lecture is a review of the type of research that led to the adoption of the American National Standard for Polyethylene Encasement for Ductile Iron Pipe Systems (ANSI/AWWA C105/A21.5) and numerous case histories that establish the efficacy of polyethylene encasement. Throughout the presentation 75-years of corrosion research and development are highlighted. As the talk begins to close, the development of the Design Decision Model® (DDM®) is introduced to the audience along with its associated statistical analysis. Finally, the up-to-date information on the newest type of polyethylene, V-Bio®, will be detailed and how its anti-microbial and active corrosion inhibitor laced inner layer grants an even greater level of protection.
