The Duriron Company has been involved in the development of anodes and standards for deep groundbeds for many years. Many of you know W. T. Bryan, who has since retired from the Duriron Company, but is still acting as a consultant, who chaired the NACE Technical Practices Committee, T10A7, which developed the recommended practice for the design, installation, operation and maintenance of impressed current deep groundbeds. His own paper, "Use of High Silicon Chromium Iron Anodes for Deep Groundbeds", given at the 26th Annual NACE Conference in Philadelphia, Pennsylvania, on March 2, 1970, summarized the Durco effort to that time frame, while at the same time, other papers on the state of the art were given on steel pipe anodes and other materials of construction. This well-known history is emphasized merely to stress the point that the Duriron Company has, over the years, conducted an intense research and development program in the search for a better anode design for both deep groundbeds, as well as other types of installations. Naturally, in any design, we would want to take advantage of all the excellent qualities of the high silicon chromium iron material, and in doing so, many design criteria were investigated.
