A Comparison of the Physical Properties of Various Kinds of Cast Iron Pipe by F. N. Menefee and A. E. White, provides an in-depth analysis of different types of cast iron pipes based on a series of tests conducted for the Water Board of the City of Detroit. This comprehensive study, aimed at comparing the service effectiveness of six-inch and eight-inch pipes, involved several types of cast iron pipes including Monocast, Universal, McWane, Delavaud, and French, each manufactured through various methods. The report details physical and chemical tests such as tensile resistance, radial compression, and impact resistance, and discusses the significance of uniformity in pipe wall thickness. Noteworthy conclusions include the advanced performance of the Delavaud pipe, which showed the highest overall characteristics, while American Sand Cast and French pipes were often rated lower. The results emphasize the importance of manufacturing methods and material uniformity in achieving optimal pipe performance.
