ASME B16.5 - B16.47 - MSS SP-44 ???
ASME B16.5 - B16.47 - MSS SP-44 ???
(OP)
For large flanges (>24"Ø), I've always used B16.47. A question has arisen around here about dimensions for "ANSI" vs MSS dimensions. Seems a 30"Ø valve was ordered with 600# "ANSI" flanges. I'm thinking this means B16.47 since "ANSI" is now spelled "ASME".
So the question for the group here becomes: Is there any difference between "ANSI" and MSS SP-44 / ASME B16.47?

ANSI B16.5 - American standard flanges
B16.47 a - serie is former MSS SP-44
B16.47 b - serie is former API 605
see the notes to the right.

Hope they ordered 2 of them.
We will design everything from now on using only S.I. units ... except for the pipe diameter. Unk. British engineer

Now I have to find out just exactly what the client is getting after he ordered it as simply "ANSI" 600# RF Flange. :p
