Abstract
It is known that the bolt loads of gasketed flanged joints decrease in some degree after the assembly due to the creep-relaxation characteristics of gasket. If the bolt loads are greatly reduced, the emission from flanged joints may increase and serious accidents shall occur if things come to the worst. The effect of the creep-relaxation characteristics on the bolt loads of gasketed flanged joints must be clarified. A gasketed bolted joint, in which two hollow cylinders and a gasket is tightened by a set of nut and bolt, is used to clarify the effects of the creep-relaxation characteristics of gaskets on the reduction of bolt loads in this paper. We tried to clarify the phenomena and necessary modeling and experiments were carried out. It is pointed out that the reduction of bolt load cannot be overlooked when stiffer bolts are used in gasketed joints.
