Progress in Gasket Testing—Milestone Results
Publisher: The American Society of Mechanical Engineers (ASME)
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 ...
Weight Loss Correlation for Sheet Gasket Materials
Publisher: The American Society of Mechanical Engineers (ASME)
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 ...
Tube-Tubesheet Joint: A Proposed Equation for the Equivalent Sleeve Diameter Used in the Single-Tube Model
Publisher: The American Society of Mechanical Engineers (ASME)
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 ...
Estimation of Residual Stresses in Hydraulically Expanded Tube-to-Tubesheet Joints
Publisher: The American Society of Mechanical Engineers (ASME)
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 ...
The Effect of Gasket Creep-Relaxation on the Leakage Tightness of Bolted Flanged Joints
Publisher: The American Society of Mechanical Engineers (ASME)
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 ...
Effect of Mean Stress and of Mean Strain in Low-Cycle Fatigue of A-517 and A-201 Steels
Publisher: The American Society of Mechanical Engineers (ASME)
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 ...
Cumulative Fatigue Damage Under Stress-Controlled Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
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 ...
Axial Strength of Tube-to-Tubesheet Joints: Finite Element and Experimental Evaluations
Publisher: The American Society of Mechanical Engineers (ASME)
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 ...
