If you're dealing with other materials or other end connections, let us know - it'll be a different ASME standard.

Are you sure you want to do this ?
At the intrados, you may end up with two welds very nearly overlapping.
If you are using thin walled stainless material (10S or 5S) the HAZ would definitely overlap.
Tell us more about the design and your need to use a short radius component.

I do not believe that there is an ASME standard that covers butt welded 45 degree short radius elbows.
If anyone is aware of a standard that covers butt welded 45 degree short radius elbows please let me know.

If you must have Short Radius, take a 90 degree Short radius elbow, cut it in half and re-bevel the end.

B16.9 does, in fact, address 45° SR elbows. As pennpiper pointed out, they can be cut from 90's and made/certified in the factory as B16.9 products.

I think curlyjackme is looking for a 45 degree short radius butt welded elbow to some spec.

Thanks for the follow-up. Can you tell us which way your project wound up going - field cut or factory made?

We finally decided to buy SR 90 degree elbows and cut them in half and re-bevel them, and used them.
