No other pipe material has a record of performance to equal that of iron pipe. The strength of modern Ductile iron pipe offers advantages in design, installation and operation over a minimum average service life of 100 years.
Discover its many advantages and find out why Ductile iron pipe is the pipe material of choice for today's water and wastewater pipeline infrastructures.
Ductile iron has greater strength and ductility than gray iron. Those properties allow it to be used effectively in a wide variety of industrial applications, including seismic considerations, pipe on supports, wastewater applications, subaqueous crossings, trenchless installations, thrust restraint, and more.
With more than six decades of outstanding field experience, Ductile iron pipe is widely recognized as the industry standard for modern water and wastewater systems.
The basis of the design standard for Ductile iron pipe is that when subjected to internal pressure and underground loading conditions, it behaves as a flexible conduit and rerounds under pressure. Therefore, the pipe is designed separately to withstand external loads and internal pressure.
Ductile iron pipe is resistant to corrosion in most soils. In more aggressive soils, V-Bio® enhanced polyethylene encasement wrapped around the pipe helps mitigate corrosive conditions. Cement-mortar lining on the inside increases the pipe’s resistance to corrosion, as well.
