Design of flange under bending moment and equivalent pressur - 02/06/13 04:11 AM
Dear all
Problem is about design of a flange for pressure plus external loadings (Force and Bending Moment). The equipment is ASME SEC VIII DIV.1
We found the following in PV Elite output.
H = (3.14/4) *G^2 * Pequivalent---------(1)
But
Hp = 2b*3.14 G m P --------(2)and
Hydrostatic end force Hd= (3.14/4) B^2 P ------(3)
The query is why equivalent pressure is not used in equationw (2) and (3).
I understand that it is logical because the additional pressure due to F and M do not act on inside but only at gasket location. but I want to know the reference for the same from where PV Elite has taken this approach.
I will be thankfull if any user or PVElite reply for the same
