Few investigations have been carried out on the characteristics of bolted joints with a gasket subjected to external bending moments. In this paper, the characteristics of the pipe flange with a full face metallic gasket subjected to external bending moments are examined. In the analysis, the pipe flanges and the gasket are replaced with hollow cylinders. The contact stress distribution, the force ratio for the external bending moment (the relationship between an increment or decrement of the bolt axial force and the external bending moment) and the maximum stress produced in the bolts are analyzed as axi-asymmetrical problems using a three-dimensional theory of elasticity. For verification, experiments are performed with respect to the force ratio for the external bending moment and the maximum stress in the bolt. Analytical results are in fairly good agreement with experimental ones.
