If anybody knows, please inform me of the following:

1. Edition of
ASME B16.5(dimension & pressure/temperature rating) :
SEC.II, Part D, Table 1A/1B(for ASME SEV VIII Div.1 Material) :

2. FLANGE FLEXIBILITY MODEL
: Which material can I refer to for this model or method.

3. Applied external Load
: A manufacturer insists that only sustained loads(excluding thermal loads) are considered in flange design & calculation. Is this right?

4. Code edition
Which edition of B31.1 and B31.3 is complied for each CII version (v5.1, v5.2 and the previous ones if possible)?
I suggest that COADE notify applied edition of each code when new version of CII is released,
