Required thickness for Integral Flange (special Design)

[Jazz79]

hi Friends,

I'm designing a special integral flange, I need to know how to calculate the required thickness of the flange,

Should I use the same formula for calculating blind flange as specified on UG-34 ASME on page 35?

Regards,

YOu should use appendix II of ASME BPV Sect Viii div 1.

Chunlin,

yes I'm using App. II but it does not say as to how they calculate the flange thickness on a weld neck type flange,

but for the special blind flange they refer you to UG-34 for the formula used for flange thickness
