Overview

Since its introduction into the marketplace in 1955, Ductile Iron pipe has been recognized as the industry standard for modern water and wastewater systems. More than six decades of field experience have proven its strength, durability, and reliability for transporting raw and potable water, sewage, slurries, and process chemicals. Ductile’s high degree of dependability is primarily due to its high strength, durability, impact and corrosion resistance. Designed and manufactured to the industry’s most stringent standards, Ductile Iron pipe resists damage during shipping and handling, and, once installed, withstands the most demanding operating conditions, including water hammer, frozen ground, |

deep trenches, areas of high water table and heavy traffic, river crossings, pipe on supports, rocky trenches, and areas of shifting, expansive, and unstable soils. Installation is simple. Unlike some pipe materials, Ductile Iron pipe requires no complex line-and-grade drawings or laying schedules. It can be installed in a wide variety of trench and bedding conditions and can be easily cut in the field. Direct tapping, even in straight lines, doesn’t affect its integrity. And, once installed, Ductile Iron pipe is virtually maintenance free. The pipe is manufactured in 6m nominal laying lengths and 100 – 1000 mm diameters in a range of standard pressure classes and nominal wall thicknesses. Ductile Iron is furnished with several different types of joints, and a wide variety of standard fittings are available without special order. Although Ductile Iron pipe is usually furnished with cement mortar lining, optional internal linings are also available for a wide range of special applications. And Ductile Iron’s generally larger-than-nominal inside diameters, combined with its high flow coefficient, offer substantial savings on pumping and power costs over the life of the pipeline
