Threaded Pipe

What is the proper way to label a pipe?

I've got a leader pointing to the pipe and stating:

LOW CARBON STEEL PIPE 2.875" O.D.

Forget i said anything. I'm an idiot.

I just realized that you call out pipe by the inside diameter. lmao

2 1/2" sch 40 pipe ... or what ever is approriate for the pipe your using

oh and I usualy don't label carbon steel pipe , I usually only call out the material if it is something other than carbon steel, for example, 2 1/2" SCH 40 pipe 304L SS

Forget i said anything. I'm an idiot.

I never show that much detail in my plan views, but in fabrication details I would if it calls for it. Most of the time, in the spec its noted exactly what piping systems get the necessary material (pipe type, schedule size, etc).

Yeah, this fab plan is for one of our sub contractors.

Pipe fitters know from the nominal pipe size what the ID and OD pipe dimensions are. They don't need ID or OD, but nominal dimensions. If you start dimensioning the ID or OD, you'll just confuse the crap out of them, not to mention tick them off.

Anytime I did things for the fab guys, they knew from what material the pipe was simply from how I tagged the piping system.

Word......

if you do need to pull off some dimensions just remember that as an industry typically pipe is dimensioned by I.D. and duct is O.D.
