The Evolution of Ductile Iron Pipe | DIPRA

According to historical accounts, the very first iron pipe was installed in Siegerland, Germany, aimed at supplying water to Dillenberg Castle. Notably, King Louis XIV of France also utilized iron pipes to link the Seine River with his extravagant palace of Versailles. Remarkably, this original installation remains functional, contributing to the operation of the palace's stunning fountains and gardens.

The creation of ductile iron, the material used to fabricate ductile iron pipe, can be traced back to the innovations of American metallurgical engineer Keith Mills. In collaboration with Albert Paul Gagebin and Norman Boden, Mills was awarded U.S. patent 2,485,760 for a Cast Ferrous Alloy. A critical distinction between cast iron and ductile iron lies in the form of carbon: while cast iron has flaky carbon, ductile iron features nodular carbon. This fundamental difference enables ductile iron pipes to bend rather than break, allowing for decades of reliable service.

Ductile iron pipe debuted in the commercial sector and has since become the benchmark for contemporary water and wastewater infrastructure, recognized for its exceptional strength and longevity. Over the years, ductile iron pipe has consistently proven its reliability in transporting raw and potable water, reclaimed water, and sewage.

While its historical significance is noteworthy, the real value of ductile iron lies in its prospective future. Modern iterations of ductile iron pipe boast a lifespan exceeding one hundred years. In comparison to gray iron, ductile iron exhibits twice the strength. This robustness is particularly beneficial in disasters like earthquakes, ensuring communities have uninterrupted access to clean water.

The Ductile Iron Pipe Research Association (DIPRA), originally formed as the Cast Iron Pipe Publicity Bureau, was established to advocate for the advantages of iron piping. It continues its mission by providing vital information to utilities and engineering consultants regarding ductile iron piping. DIPRA also collaborates with various organizations to spread awareness about the benefits ductile iron offers.

In recognition of its history, the Cast Iron Pipe Century Club, which comprises over 500 water utilities, was founded to honor cast iron water mains that have functioned for over a century. Additionally, the Cast Iron Pipe Sesquicentennial Club was established to celebrate cast iron water utilities operational for at least 150 years. Despite ductile iron's replacement of cast iron, these clubs still receive unwavering support from DIPRA.
