| Abstract: | Bolted flanged connections are liable to failure, which work for a long time under the operating conditions that pressure and temperature change frequently By means of the application of the constitutive equation of gaskets to the load deformation equation of bolted flanged connections, a method to calculate the cyclical stress of bolts is put forward when the pre tightening conditions are known |

| Keywords: | bolt elevated temperature flanged connection cyclical stress |
