Ductile iron pipe, a product of advanced metallurgy, offers unique properties for conveying water under pressure and for other piping uses. It combines the physical strength of mild steel with the long life of gray cast iron.

 

Ductile iron offers the greatest possible margin of safety against service failures due to ground movement and beam stresses. Virtually unbreakable in ordinary service, it also provides increased resistance to breakage caused by rough handling in shipping and installation. The corrosion resistance of ductile iron pipe has been proven in a wide variety of accelerated tests to be at least the equal of gray cast iron.

 

In addition to the benefits of long life, corrosion resistance, high structural strength, and tight joints, ductile iron is also readily machinable, an important requirement in any pipe that must be drilled, tapped, or cut.
