Hello
I would like to know if there are dimension tables for reducers (concentric and excentric) for ASME B16.5, or I have to use the reduction relations for flanges.
Also I would like to know about if there are any reduction fittings on B16.11, because the Standard talks about the method of designating outlets of reducing tees and crosses but inside the Standard i can't find a table about them. So my question is about which relations of reduction are there for these elements and which are the ones that the Standard contemplates (reducing cross on both outlets? all outlets are different?).
Thank you already for the help.

I don't understand the need for your question.

A link like this:

and this
"http://www.weldbend.com/Fittings/fittingsindex.htm"
should give you all you need

Please Refer ASME B 16.9 ( standard for Seamless fitting) i am sure you will get the information what you want.
