Products and brands

In the United States, the Ductile Iron Pipe Research Association represents manufacturers of ductile iron pipe. The association provides research on and promotes the use of ductile iron piping in utility projects (water and sewer), focusing on its strength, recyclability and life cycle cost compared with alternative products such as PVC. The US industry is also represented by the National Association of Pipe Fabricators. Outside of the US, the ductile iron pipe industry is supported by associations including the European Association for Ductile Iron Pipe Systems.

After the 2008 financial crisis, the pipe industry as a whole, experienced a decrease in sales in the US due to municipalities deferring replacement of water mains and reduction in new home construction. According to a report published by The Freedonia Group in 2011, economic recovery from the 2008 crisis is likely to expand ductile iron's market share in the large diameter pipe market.
