About Ductile Iron Pipe

The Value of Ductile Iron Pipe

With an anticipated service life of 100+ years, Ductile iron pipe is the most cost-effective material over a pipeline’s service life vs. other materials.

When assessing the full value of your pipe selection, you should consider:


Material Production Costs

The production phase involves costs for raw material extraction, pipe production and pipe transportation.

Installation Costs

The installation phase involves the operational costs of the necessary equipment as well as the cost of any bedding material required for installation of each pipe material.

Operation and Maintenance Costs

The operation and maintenance phase involves the costs associated with pumping as well as performing repairs and regular maintenance activities over the 100+ year design life.

End of Life

Once a pipe reaches the end of its service life, it can either be exhumed for future uses, such as recycling or disposal, or it can be abandoned in place.



The projected service life for modern Ductile iron pipe is 100+ years.
