Bolt area verification for bonnet flange connections per ASME B16.34 pressure class rating. Based on ASME B16.34 standards.
Open Calculator →
Industry-standard bolt area requirement for valve flange connections.
Bolt requirement directly linked to pressure class rating (Class 150-2500).
Standard B16.34 formula coefficient for bolt area calculation.
Both total area and single-bolt minimum area verified.
Instant pass/fail: actual bolt area vs. required minimum.
Flexible gasket outer diameter input for various flange designs.
Input gasket OD, pressure class, bolt specs (count, area, allowable stress).
Ag = pi/4 * dg^2 from gasket outer diameter.
Ab_required = Ag * Class / (65.26 * Sb).
Compare actual total area to required; pass/fail displayed.
Enter your design parameters and get instant verification results.
