Generally, the widely used flange gaskets are sheet gaskets, corrugated metal gaskets, ring gaskets and spiral wound gaskets, which have many different sizes according to the inner and the outer diameters. Among them, the ring gaskets, known as the RTJ [3, 4], are mostly used in offshore oil and gas pipelines and are designed to work under extremely high pressure. They are solid rings of metal in different cross sections like oval, round, octagonal etc. Since the performance of flange joint is determined by the strength and sealing capability, it is necessary to conduct the research for the behavior characteristics and the contact pressure between the flange and the gasket, in order to investigate whether the joint is able to play a role under the given conditions.

Manage. 101, 658–665 (2015) 7. kr Abstract. Flange joint to provide a seal is constructed by inserting a gasket between the two flanges and fastening them with bolts.

The stress of the gasket when subjected to the design pressure is reduced by approximately 17% for the octagonal gasket and by about 16% for the oval gasket. 3. The contact area of the octagonal gasket is wider than that of the oval gasket, while the contact pressure occurring in the oval gasket is higher than in the octagonal gasket. 4. The mean contact pressure on the oval gasket is high by 27% in comparison with the octagonal gasket with the same size. 5. Since the contact pressure of the gasket subjected to the design pressure is reduced by 19% for the octagonal gasket and by about 9% for the oval gasket, it is supposed that the oval gasket is more advantageous from the sealing capability point of view.
