I think (emphasis on think only) that Idod will last longer because of the manufacturing process. It's more a steel/zinc alloy than coated steel. That said I don't know for sure. Rust/corrosion does not occur in environments without oxygen, consider Lake Michigan where nothing lives below 100 feet and all those sunken ships have uncorrupted cargo waiting for salvage, so a nitrogen environment in place of an oxygen/nitrogen (air) environment (inside the pipe) should be devoid of any deterioration at all.
