note deciphering
i am posting here as i am not sure what other forum to place this in.  i have a drawing of a 1080 gallon tank, working pressure of 200psig, listed as a vertical air tank.  there are two flanged openings, and i have never worked with flanged openings before.  there is a note pointing to one of the openings that reads:
6"-150# r.f.s.o.
flg. w/sch. 80
pipe x 7 5/8"lg.
what do letters in greenfff"> mean?
"art without engineering is dreaming; engineering without art is calculating."
it means "i don't want anyone to be able to read these letters on a purple background..."
i believe it means raised-face slip on (a specific type of flange). anyone, please correct me if i'm wrong... i'm not a flange expert.
a vendor of rfso flanges:
yes, rfso raised-face slip on. i would leave the periods off.

i think there's a pressure vessel forum or similar, may have someone who knows for sure.
