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.
