ASME Flange Fabrication
ASME Flange Fabrication
(OP)
Good morning,
I need to fabricate some ASME Flanges B 16.5 and i can't find where in the ASME code it says if i can build from a whole plate (one single disc) or if i can fabricate with crankshaft method.
The diameter i must build is something near Ø600mm
Can anyone help me point the area where it specifies?
(i annexed an image to help the understanding)
Thanks in Advance!

What is "crankshaft method"? What does "near 600mm" mean?
And why make a B16.5 flange in the first place? They are widely available.

The problem with sloppy work is that the supply FAR EXCEEDS the demand

SnTMan this is the image, english is not my mother tongue, so i do not know how to spell the word to fabricate a flange in the methode as stated in the image above,
The near 600mm was supposed to mean a 24" flange for a manway,
And by building it from plate, was because of lack of time to buy from vendors and we have plates to spare in stock.
Sorry if i was a little bit confusing,
Thanks in advance!

You could weld from sections as shown, but I personally would prefer single piece. Usually less expensive without the welding and NDE.
You cannot just make it from plate and call it a B16.5 flange.
