[leyton]

Dear colleagues,

Can someone supply me with detailed description of the following flanges:

1. Hub flanges butt welds, 24" - 900 - A350 LF2.
2. Hub flanges butt welds, 30" A105.

Thanks in advance!

leyton,

You should look in ASME B16.5 for 1/2"-24" and B16.47 for 26" and above under "Welding Neck".

As to the facing, you did not mention raised face (RF) or ring-joint type (RJT) so you will have to work it out. Both are described in detail in those standards.
