Whoops, you are right. I should look in the code before shooting from the hip. "Corrosion Resistant" (3.8.1.2) versus "Corrosion Retardant"(3.8.1.3). With the ABF coating obviously being the latter. So... technically galvanized pipe falls under the definition of "Corrosion Retardant"???... but it is included in the options of the quoted code section so it applies.
So it looks like the cost effective options are limited. Interesting topic though. I might have interpreted it the same...that a Nitrogen filled system would place it in the corrosion resistant category.
