RISEffect of Material Strength on Ductile Failure of Steel in Pressure Vessel Design
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Pressure vessels and their components are commonly designed with the ASME Boiler and Pressure Vessel Codes. One of the requirements when pursuing the design by analysis route is to design these equipment against ductile ...
Evaluation of a Pipe–Flange Connection Method Based on Cold Work
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The conventional joining method of a pipe and a flange uses welding. However, welded pipe–flange joints have the drawback with the inherent distortions and residual stresses resulting from the welding process, which can ...
Load Carrying Capacities of Butt Welded Joints in High Strength Steels
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The aim of this study is to investigate the influence of yield strength of the filler material and weld metal penetration on the load carrying capacity of butt welded joints in highstrength steels (HSS) (i.e., grade S700 ...
The Sensitivity to the Lode Parameter in Ductile Failure of Tubular Steel Grades
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Ductile failure in steels is highly controlled by the stress state, characterized by the stress triaxiality (T) and the Lode parameter (L). The ASME Boiler and Pressure Vessel Code requires pressure vessels to be designed ...
New Ring Specimen Geometries for Determining the Failure Locus of Tubulars
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Pressure vessels designed in accordance with the ASME BPVC code are protected against local ductile failure. Recent work has shown that local ductile failure highly depends on the stress state characterized by both stress ...
Thermomechanical Evaluation of the Performance and Integrity of a HDPE Stub-End Bolted Flange Connection
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: In this study, the integrity of a manhole structure made of a 78 in. high density polyethylene (HDPE) stub-end, steel ring, and blind flange, sealed with a compressed nonasbestos fiber (CNAF) gasket is investigated by means ...
Burst Pressure Prediction of Pipes With Internal Corrosion Defects
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Corrosion in pipeline walls can lead to severe loss of material to a point which will cause complete loss of pipeline integrity. The contemporary approach of corrosion prevention is to use internal lining system to isolate ...
Finite-Element Analysis of the Installation Process of a Novel Corrosion Protective Kevlar-Reinforced Flexible Composite Liner
Publisher: American Society of Civil Engineers
Abstract: Internal corrosion in pipelines is a persistent problem in the oil and gas industry. Available conventional rehabilitation techniques to stop corrosion losses and prolong the life of the pipeline use an internal lining ...
Integrity Assessment of Internally Corroded Pipelines Rehabilitated With a Kevlar-Reinforced Flexible Liner
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Contemporary approach of corrosion prevention is to use internal lining system to isolate the corrosive medium from the host pipe's inner surface. The liners serve to offer a longer lifecycle of pipelines, as well as a ...
