Ductile Iron Pipe

Definition - What does Ductile Iron Pipe mean?

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.

Trenchlesspedia explains Ductile Iron Pipe

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.
