Who We Are
From our 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, the organization’s initial role was to promote the superior qualities of iron pipe through advertising programs. Over time, we have evolved to become a technically based and research-oriented organization. DIPRA provides a variety of resources such as publications and videos, representation on standards-making committees, technical research on applications-based topics (such as corrosion control and design of Ductile iron pipe), and personal technical services through our Regional Engineer Program.
