Hello all!

ASME B31 codes use pad thickness when calculating the SIF of reinforced fabricated tees, but not the diameter of such pads. Is there any minumum required diameter of the pads to comply with B31? (let's assume that such pad is only required for SIF reducing, not for branch reinforcement according to section 104.3.1 of ASME B31.1).

Thank you for your help.

Best regards
