Comparative Risks of Hydrostatic and Pneumatic Pipeline Testing
(The American Society of Mechanical Engineers (ASME), 2020)An important step in a pipeline-construction project is confirming that the piping and facilities are adequate for the expected operating pressures via static strength tests. All fluids have mass and internal energy. Fluids ... -
Local Constitutive Behavior of Undermatched Welded Joints in Pipeline Steel Using Digital Image Correlation Technology
(The American Society of Mechanical Engineers (ASME), 2020)Although the identification of local constitutive behaviors is possible based on digital image correlation (DIC), few studies have been reported that characterize the properties of the girth-welded joints of pipeline steel. ... -
On the Interrupted Creep Test Under Low Stress Levels for the Power Law Parameter Extraction
(The American Society of Mechanical Engineers (ASME), 2020)Low stress interrupted creep test, as an interim compromise, can provide essential data for creep deformation design. However, there are no clear guidelines on the characterization of the terminating time for interrupted ... -
Characterization of Limit State for Seismic Fragility Assessment of T-Joints in Piping System
(The American Society of Mechanical Engineers (ASME), 2020)Fragility assessment requires characterization of a component or system's performance through a performance function/limit-state equation. The exceedance of limit-state is representative of failure or damage state. For the ... -
