Fitting Set back was created by Wayne Lloyd
I hope I am in the right forum. Any way, here goes. I am trying to find info on set back dimensions when welding slip-on flanges to fittings (Ells,Tees, Reducers, etc.). Thanks for any help.

Why use slip on flange?
This would normally mean having to go elbow-pipe-so flg.
I would suggest it is more appropriate top go with a weld neck flange, fitting to fitting with an elbow, reducer etc.
My 2c worth!

Replied by Anton on topic I have taken this extract
I have taken this extract from Section 1D - Flanges, Gaskets & Bolts (Just the basics) of the pipingdesgners.com taining section.
www.pipingdesigners.com/Training ... n%201d.htm
"The slip-on flange is positioned so the inserted end of the pipe or fitting is set back or short of the flange face by the thickness of the pipe wall plus 1/8 of an inch. This allows for a fillet weld inside the SO flange equal to the thickness of the pipe without doing any damage to the flange face. The back or outside of the flange is also welded with a fillet weld."
Hopefully this will help.

We are working on a project for a client and the client is supplying all material (which is sometimes a problem). All material has been purchased and received. Also, like you, I would prefer to use weld necks or even stub ends with back up flanges.
Thanks, Wayne

If I may, I'd like to post a chart here that deals with slip-on flanges. Working in the oilfields, I find them very useful. However I can see their problems for designers work in more stringent areas. My $0.02 ...Mark

Mark, this is exactly what I was looking for. Do you happen to have info on set back on tees? Also a lot of designers do not realize that the interference between the throat of the ell and the hub of the flange will not work with the formula (t+1/8").
Thanks, Wayne
