The April 2017 meeting of NWA ASCE will begin at noon, Wednesday, April 5, 2017 at Whole Hog Cafe in Bentonville. Following the review of old business and introduction of new Branch business in accordance with our bylaws, Allen Cox, PE, of the Ductile Iron Pipe Research Association (DIPRA) will present Corrosion and Its Control, Polyethylene Encasement (V-Bio), for Ductile Iron Pipelines. Professional development hours will be available for ASCE members.

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 ModelTM (DDMTM) is introduced to the audience along with its associated statistical analysis. Finally, the up-to-date information on the newest type of polyethylene, V-BioTM, will be detailed and how its biocide and inhibitor laced inner layer grants an even greater level of protection.

Mr. Cox is a graduate of the University of Tennessee at Knoxville in Civil Engineering.  Allen’s previous professional experience includes employment with Texaco, Inc., the US Army Corps of Engineers (Memphis Branch), a Tennessee-based construction company and Memphis Light, Gas and Water Division.
Mr. Cox joined DIPRA in 1981.  He is a registered Professional Civil Engineer in the State of Tennessee, a NACE International Certified Corrosion Specialist and is Envision SP credentialed. He is a member of the American Water Works Association (AWWA), National Association of Corrosion Engineers (NACE) International, American Society of Civil Engineers (ASCE) and the Water Environment Federation (WEF).

From its inception more than 100 years ago, the Ductile Iron Pipe Research Association (DIPRA) has provided accurate, reliable, and essential engineering information about cast iron—and now Ductile Iron—pipe to a wide variety of utilities and consulting engineers.

Founded in 1915, initially the organization’s role was to promote the superior qualities of iron pipe through advertising programs, but it evolved into a technically based, research-oriented organization providing a variety of technical brochures and publications, representation on standards-making committees, technical research on a variety of applications-based topics such as corrosion control and design of Ductile Iron Pipe, and personal technical service through our regional engineer program. While DIPRA member companies have different names and locations, they share a common commitment to produce and deliver the finest quality water and wastewater pipe material in the world, Ductile Iron Pipe, at the greatest possible value to its purchasers.
