Ductile Iron Pipe
Ductile iron pipe refers to the pipe made by high-speed centrifugal casting of centrifugal ductile iron machine after casting molten iron above No. 18 with the addition of nodularizer, referred to as ball pipe, ductile iron pipe and ductile cast pipe. Mainly used for the transportation of tap water, it is an ideal material for tap water pipelines.

Ductile iron pipe, made from ductile cast iron, is a graphite-rich cast iron in which the graphite has a spheroidal shaped molecular structure. This molecular structure makes the cast iron less brittle and more resistant to impact than the other varieties, which have a flaky structure. The ductile iron pipe is used in trenchless technology for water and sewer lines. Ductile iron pipes can have a life of more than 100 years if they are coated within and without with non-corrosive linings like cement, asphalt, paint, or polyethylene encasement.

Ductile iron pipe has been the pipe of choice when it comes to installing water and sewer pipelines because this material can withstand the toughest conditions. It can be used for installing new pipelines or for replacing existing pipelines. Two of the most important methods used in trenchless technology, namely horizontal directional drilling and pipe bursting, are increasingly making use of ductile iron pipe because of its versatility and toughness. It is possible to assemble these pipes quickly in cartridge style, making this type of pipe a great option for undertaking repair or installation work in places with heavy human and vehicular traffic. When space is an issue, it is also possible to pull or push these pipes through the ground using long strings.


Ductile iron is produced by adding a closely controlled amount of magnesium alloy to a molten iron of low phosphorous and low sulfur content. The magnesium alloy addition produces a remarkable change in the microstructure by causing the carbon in the iron to assume a spheroidal or nodular shape, (as contrasted to the flake form of graphite in gray cast iron), and at the same time producing a finer grained iron matrix in the surrounding ferrite structure. As a result of this remarkable change, a far stronger, tougher, and ductile material is obtained.


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.
