This paper presents the results of sealing performance test on the slip-on type pipe flange connections for 8 inch and 16 inch. The flange connections are subjected to internal pressure and bending moment. Internal pressure is applied by Helium gas and the bending moment is loaded through 4 points bending equipment. Gas leak rates are measured by pressure decay method. During the test, the variations in the axial bolt force are monitored for all the bolts by strain gages. The pipe stress at the junction of pipe and flange is also measured. Analyzing the measured data, the mechanical behaviors of the slip-on type flange connections under internal pressure and bending moment as well as the sealing performance are clarified.
