Stress and Strength Analysis of Concentric Reducers Consisting of Plates
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a new kind of piping component—a concentric reducer consisting of plates. Authors performed experimental and elastic, elastic-plastic analyses on five test models having different ...
Effect of Geometry of Grooves on Connection Strength of Hydraulically Expanded Tube-to-Tubesheet Joints
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The object of this paper is to investigate the effect of the geometry of circumferential grooves on the connection strength of hydraulically expanded tube-to-tubesheet joints of heat exchangers. ...
Study of Elastic Strength for Cylinders With Hillside Nozzle
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The objective of this paper is to investigate the elastic strength of cylindrical vessels with hillside nozzle under out-of-plane moment on the nozzle. A total of 5 model vessels with different ...
Plastic Analysis for Cylindrical Vessels Under In-Plane Moment on the Nozzle
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The objective of this paper is to determine the plastic limit moment for cylindrical vessels with a nozzle under in-plane moment loading. Three full scale test models with different d/D ratios ...
Study of Plastic Limit Load on Pressurized Cylinders With Lateral Nozzle
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The objective of this work is to study the plastic limit load of cylindrical vessels with different lateral angles θ under increasing internal loadings. Three full size test vessels with ...
Influence of Pad Reinforcement on the Limit and Burst Pressures of a Cylinder-Cylinder Intersection
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The purpose of the paper is to provide experimental results for the limit pressure of a vessel-nozzle intersection under internal pressure with and without an intermediate pad-reinforced opening ...
The Effect of the Welding on the Residual Contact Stress in the Expanded Zone of Expanded-Welded Tube-to-Tubesheet Joints
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The fabrication of stainless steel tube-to-tubesheet joints of heat exchangers consists of welding after hydraulic expansion. Here, this process is simulated by use of the finite element method, ...
On the Design of Horizontal Pressure Vessels
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The objective of this paper is to provide analysis results of displacements and localized stresses in horizontal pressure vessels which were determined by using the three-dimensional finite element ...
Fatigue Behavior of Tube-to-Tubesheet Expanded Joints
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In order to study the fatigue behavior of expanded tube-to-tubesheet joints for steam generators and tubular heat exchangers under cyclical loading, both static and fatigue tests were performed. ...
Reliability Factors and Tightness of Tube-to-Tubesheet Joints
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The main purpose of this paper is to provide an applicable method to establish reliability factors for expanded tube-to-tubesheet joints. The paper also reports on the results of a preliminary ...
