A numerical investigation of the sealing performance and the strength of a raised face metallic bolted flange joint

The development of leakage and strength a metallic bolted flange joint are investigated in this work. Finite element analyses 2D 3D have been developed using ANSYS to study steel bolt with an aluminium gasket. pressure-penetration criterion (PPNC) has used model fluid propagation between the Validation was performed benchmark test, published joint; agreement results is excellent. Results showed that finite method PPNC good behaviour compared other methods, which relatively time-consuming expensive. influence dimensions on maximum stresses study. Furthermore, axisymmetric FEA models very good, so latter can be save computational time. This undertaken as preliminary larger project about joints made composite materials.
