Reductions on ASME B16.5 and B16.11

[JuanVega]

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?). Maybe there is a reference to another Standard that I haven't seen.
Thank you already for the help.

Juan-

B16.5 Table 9 has dimensions for concentric and eccentric flanged reducers for Class 150, other tables have the dimensions for other classes.

B16.11 paragraph 6.5 provides dimensional guidance for reducing fittings covered under that standard.

JuanVega,

See ASME B16.9 Table 11 for reducer buttweld fittings.

thank you jte and ApC2Kp for the help.
Although I still have some doubts about the reduction ratios.

If you see the B.16.9 Standard for reducers, reducing tees, etc. (for example table 8 for reducing tees and crosses) you'll see a series of reduction ratios for each component (reduction from radio A to radio B, from radio A to C, from radio A to D, then from radio B to C, from radio B to D, from radio B to E, and so)and their dimensions. I would like to know if that series of reduction ratios are the ones that i would use for my reducing components in the other standards (B16.5, B16.11) or maybe there is another reduction ratios from another standard that i should use. Thank you very much for the help, I'm new in this discipline of piping.
