I do lots of plumbing drawings, I'm sure I could draw one.
My "plumbing" is most often plastics and/or lined steel.
Chemical industry "stuff."
Attached *.dwg file is 6" pipe 'n fittings. The six inch 'tee' has a 2" threaded bottom outlet (could be up to 6" or more). Something like this? All fittings are ANSI dimensioned.
Playing a bit this AM, thought, "Two inch plug? Too small!"
There are numerous ways to accomplish this mission.
