Exposed Piping
(OP)
I have a floating dock, several - actually 1400' long with 400' spurs, am doing a dry standpipe. question is rather than use galvanized pipe couldn't I just have it painted and meet the corrosion requirements, all grooved items are factory painted, metra-flex fire loop at all "expansion/contraction" joints

RE: Exposed Piping
6.1.2.4 "Where corrosive conditions exist or piping is exposed to the weather, corrosion-resistant types of pipe, tube, fittings and hangers or protective corrosion-resistant coatings shall be used."
"Corrosion-resistant pipe" would be galvanized, for example.
"Corrosion-resistant COATINGS, in my humble opinion, do NOT include "paint". Examples of "corrosion-resistant coatings" (epoxy, powder metal, etc.) are in the link to a manufacturer see below .....
RE: Exposed Piping
Well after reading the relevant code passage above, I would personnally interpret corrosion resistant coating definition includes paint, even enamel paint.
Are you bidding this? Could you provide two bids, a base bid with painted CS and cost adder for int/ext galv?
Painted may meet the letter of the code, but probably won't last.. bird poop, sun exposure, owners hosing down their boats with bleach solution, etc.
