So maybe a Nitrogen filled system with "Corrosion Retardant" pipe = "Corrosion Resistant"? That covers several forms of corrosion and would probably meet the intent. The Nitrogen guys are probably already testing ;) Maybe the long term durability of the coating would have to be addressed by reapplication of a product like Potter's solution.
