Classic flat plate bending model for gate plate with free-edge support.
Free-periphery steel plate coefficient per Valve Design Manual.
Built-in corrosion margin C added to calculated thickness.
Actual plate thickness vs. calculated minimum S'B.
Allowable bending stress [sigma_W] = sigma_s / 2.3.
Even with 1.5Pn check, result stays well below actual thickness.
Input rated pressure, seal face dimensions, plate coefficient K, and actual thickness.
R = (DMN + bM) / 2.
S'B = R * sqrt(K*Pn/[sigma_W]) + C.
Compare actual tB to S'B; pass/fail displayed.
