flange thickness - pressure test (circular plate)
(OP)
What is the minimum thickness a flange (circular shape) has to have on a equipment to be used on a pressure test?
The data is:
inside diameter = 408 mm
diameter of flange = 580 mm
Pneumatic pressure test = 13.5 Bar
Material of Flange = A106 GrB (Carbon steel)
Thanks

ASME Pressure Vessel Code Section VIII Div 1 Appendix 2 provides rules for design of flanges. You can find some links to freely-available design spreadsheets by searching Eng-Tips (try the ASME or Boiler/Pressure Vessel forums) or do a Google search.
The thickness of the flange is a function of the bending moments produced by the gasket reaction forces, bolting forces, pressure end forces, etc, so the layout and size of bolts also enters into this. It is not a trivial problem.

I'd would not recommend designing this from scratch. If you want to feel involved, check the manufacturer's design.
