About Ductile Iron Pipe
The strength, durability, and long service life of Ductile Iron Pipe's predecessor, gray Cast Iron pipe, are widely recognized. The first official record of Cast Iron pipe installation was in 1455 in Siegerland, Germany. In 1664, French King Louis XIV ordered the construction of a Cast Iron pipe main extending 15 miles from a pumping station at Marly-on-Seine to Versailles to supply water to the fountains and town. This pipe served the palace gardens for more than 330 years.
Cast Iron pipe was introduced to the United States as early as 1817, when it was installed in the Philadelphia water system. Today, more than 600 utilities (in the United States and Canada) have had Cast Iron mains in continuous service for more than 100 years. Additionally, at least 21 utilities have had Cast Iron mains in continuous service for more than 150 years.
