RE: ansi b16.9 1978 edition
Don't you mean ASME B16.9 ?
RE: ansi b16.9 1978 edition
Yes I did mean Asme instead of Ansi.
Do you know where I can get a copy of that year showing that
dimension 1 1/8"
RE: ansi b16.9 1978 edition
I beleive the 38mm in 2003 edition is a typo.All of the tables I have call the dimension as 1.125" (28mm).
RE: ansi b16.9 1978 edition
NOTE:
(1) Ä and B dimensions of 29 mm and 11 mm, respectively,
may be furnished for NPS 9 4 (DN20) atthe manufacturer's
option.
