blind flanges 1

[ramjectb2]

I was wondering if anybody can give me information on where in the code book I can find the chart for the largest hole (pipe) that can be drilled into a blind flange? I have used before but can't recall where it is located now.

Table 7 of ASME B16.5. Or at least it is Table 7 in the 1996 edition I have.
