Bolting standard / strength class ASTM A193 MB8 Notes

Thread type 1) The design driver in this design case is the gasket seating condition

Number of bolts Min no. bolts = 31 n 2) Operational flange stresses (detailed above) are calculated to be up to 34.7% of strength utilisation.

Bolt spacing (max allowable 194 mm) Pb 3) Gasket seating flange stresses (detailed above) are calculated to be up to 83.7% of strength utilisation.

Bolt size (Dbeff=23.9mm, Ab=447mm²) Db 4) Required flange bolt torque = 224 Nm

Thickness of nut (15.5 mm) Check 5) Pre-load compensating for bolt relaxation = 224 Nm, which takes stress capacity to: Bolts = 58.3%, Flanges = 83.7 %

Thickness of washer (2.5 mm) Check 6) Maximum operating pressure for the flange at 550 °C is calculated to be = 1.64 MPa

Effective length of bolt (189.0 mm) Check 7) Estimated minimum flange thickness for pressure 0.57 MPa at 550 °C is calculated to be = 38.5 mm

Large diameter flanges may rotate more than small flanges designed to this code and as such may leak, particularly those sealed with non-energising gaskets under cyclic loading.

Flanges & bolting complying with AS 2129 used at maximum conditions permitted by that standard may result in high stresses and risk of leakage, particularly under hydrostatic test. These flanges should not be used with lethal content or where risk of leakage cannot be tolerated. AS 2129 flanges with full-face joints may only be used within the limits of Clause 3.21.2(b)

This programe covers the design of bolted flanged connections in pressure vessels, including inspection covers, blind flanges, bolted flat ends, sections of shells and branch connections.

This programe covers hydrostatic end-force and gasket seating. Where the component is subject to moments or other forces from external sources, these shall also be taken into consideration.
