Ductile Iron pipe is a centrifugally cast product. A controlled amount of molten iron is introduced into the rotating mold, which generates a centrifugal force that holds the iron in place against the mold until it solidifies.
Detailed standards for Ductile Iron Pipe, fittings, and appurtenances are available from the American Water Works Association (AWWA). Standard ANSI/AWWA C600, “Installation of Ductile Iron Mains and Their Appurtenances,” includes much of the information outlined in this guide. AWWA Manual M41 on Ductile Iron Pipe
