brass pop off? What is that?
"Wrong." All outside pipe sizes are not thee same. Think I`d run a few feet of 3/4 to the first opening or two, then 1/2" for the rest, depending on how many openings, then ur 1/4" hook ups. Of course, I don`t know much, I only did that crap for over 45 yrs.Pipe O.D. is all the same, its the inside diameter that changes. Referred to as schedule. I believe standard wall thickness is schedule 40. Pipe schedule used is determined by pressure and temperature for any particular application.
Bob i could be wrong as pipe over a certain size may be different OD. However are you thinking of tube? When we ran out of Schedule 80 or extra heavy i at times used tube which was used for Boiler water wall or superheaters. Say i needed a piece of two inch and i didn't have it, i took tube and turned down the end, usually only a small bit to get it to fit a socket or line up with a butt weld. Again OD is the same on pipe with the ID that changes as far as my experience.............BTW in my pipe fitters manual all pipe OD is listed the same, just my experience"Wrong."
