formula of cheak for flange​

Answer 1

Explanation:

$\huge\underline\mathfrak\color{red} Answer$

In this method, the axial force (F) and bending moment (M) on the flange are converted into equivalent pressure (Pe) using the following equations. Here G=diameter at location of gasket load reaction =(Gasket OD+ID)/2 when bo<=6 mm =(Gasket OD-2b) when bo>6 mm.

For calculating flange stresses, one needs to calculate the flange moment which is dependent on bolt load. Bolt load has to be calculated for two design conditions; operating & gasket seating and the most severe will govern. For more details of the equations and calculation methodology, the above-mentioned code can be referred.
