Flange pressure conating OF API standared FEA
Flange pressure conating OF API standared FEA
(OP)
How can i made FEA to the flange which is pressurized and bolted
ok i tried to make the following
Load constraint : Pressure
Boundary constraint : Fixed at the bolt hole
but i think its not right
so can any one help me

i miss understand what do you mean (pre stressed)
but i can say that the flange after we fabricate it we do a pressure test using water on it and bolt the two outlet with a blind flange
so the only load inside is the pressure of water which can reach 10000 psi
when i calculated the result is reasonable , its not reach 0.8 yield strength of the material

How about using a quarter model and having two symmetry boundary conditions. Then you only need an axial constraint.
