Before the production of Ductile Iron Pipe, Cast Iron Pipe is known as the most suitable pipe for the industries. After the production of Ductile Iron Pipe, it’s well known and retains all the attractive qualities from Cast Iron such as machinability, corrosion-resistance, additional strength, toughness, and ductility. The chemical properties for Ductile Iron Pipe and Cast Iron Pipe are different too.

Ductile Iron Pipe is largely used in the industry since 1955. Most probably Ductile Iron Pipe is used for modern water, wastewater systems and etc. There are more than for decades of field experience have proven Ductile Iron Pipe’s strength, durability, and reliability for transporting raw, potable water, sewage, slurries, and process chemicals. Ductile Iron pipe is good in it’s function of corrosion-resistance, it has been proven that its’ corrosion-resistance is equal or greater than the Cast Iron Pipe. With that said, Ductile Iron Pipe can be stand for more longer than Cast Iron Pipe without reparing, in a long term basis, the cost used for ductile iron pipe will be lesser than cast iron pipe.
Ductile Iron Pipe is usually manufactured by the piping supplier in 6 metre nominal laying lengths and range of 80mm – 2600mm diameters of standard pressure classes and nominal wall thicknesses. There is several methods for Ductile Iron Pipe jointing, assembling, cutting, installing, and ovality correction too. Of course, the cost for ductile iron pipe will be higher if comparing with cast iron pipe and other pipes, but it’s more economical in long run basis.
