Ductile Iron Pipe Research Association

1322 Riverhaven Place
Birmingham, AL 35244
United States

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.
