Abstract: An extensive gasket test program, carried out under the auspices of the Pressure Vessel Research Committee and supported by over 30 sponsors from 6 countries, is nearing completion. The program ...

Abstract: Elevated temperature aged tests were performed on two fiber-reinforced sheet gasket materials with acrylonitrile-butadiene rubber (NBR) binder; a compressed asbestos and a compressed aramid. Weight ...

Abstract: The tube-to-tubesheet joint analysis can be greatly simplified by considering a single tube surrounded by an annular sleeve representing the tubesheet. One of the problems is how to choose the ...

Abstract: The knowledge of residual stresses introduced in the tubes of heat exchangers during their expansion in the tubesheet holes is important because of their effect on the structural integrity of ...

Abstract: The loss of tightness of bolted flanged joints is primarily due to the relaxation of the joint; in particular, the clamping load is affected by the amount of relaxation that a gasket exhibits ...

Abstract: A number of low-cycle fatigue tests has been carried out at room temperature on two materials commonly used in pressure vessel fabrication. For strain-controlled tests, the influence of different ...

Abstract: A theoretical analysis of uniaxial cumulative fatigue damage is presented together with a large number of experimental results on unnotched specimens of A-201 and A-517 steels. The theory developed ...

Abstract: Because of their importance for the integrity of heat exchangers, the strength of tube-to-tubesheet joints, and particularly their axial strength, is of special interest. A finite element model ...
