With a properly engineered coating system, there is no known failure mechanism for Ductile Iron Pipe.
Plastic pipe starts the countdown to failure.
Utilities who allow Electrosteel USA in their system are paying >20% less for DIP than those who don’t.
Pipe accounts for almost 40% of the cost for most water distribution system projects.
The average utility increased water rates 7.2% between 2016 and 2018 citing capital improvement (i.e. buying pipe) as their #1 reason.
Prior to Electrosteel USA, there had not been a new DIP supplier in the USA since 1960.
Zinc coated DIP was tested in Watsonville, CA and the Florida Everglades in the 1950s yet wasn’t commercially available in the USA until 2014?
PVC pipe can melt if involved in a wildfire. Iron pipe doesn’t.
