Hey McCrowley, is galvanized pipe the same as black iron pipe but with a galvanized coating?

I'm not 100% sure but I think so. You could google to see what standards the pipes are made to and their pressure ratings. Personally, I wouldn't exceed a 10x mix in 2" malleable iron pipe. You could go up to 15x fairly safely if you remote fire it but I wouldn't want to be within 30' of it.

Okay, good to know. Thanks. I figured they would withstand more than 150 psi, I just didn't know how much more. I may try and do it with 300 psi fittings just to be sure, if I can find enough at a decent price. I definitely have no plans on exceeding 10x just based on what I've seen from yours and SB15s hybrids.
