vkp1,
don't you mean asme b16.9 ?
thanks dsb123,
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"
vkp1,
i beleive the 38mm in 2003 edition is a typo.all of the tables i have call the dimension as 1.125" (28mm).
general note: all dimensions are in millimeters.
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.
