RISEffect of Strength Matching and Strain Hardening Capacity on Fracture Performance of X80 Line Pipe Girth Welded Joint Subjected to Uniaxial Tensile Loading
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: By conducting curved wide plate tensile tests for girth welded joints of X80 line pipe containing a surface notch in the weld metal, the effects of strength matching on fracture performance ...
Effects of Prestrain on Fracture Toughness and Fatigue-Crack Growth of Line Pipe Steels
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Crack-tip-opening displacement (CTOD) and fatigue-crack growth tests were conducted for several line pipe steels with uniaxial tensile or compressive prestrain, εpr. Critical CTOD decreased with ...
Effect of Prestrain on Tensile and Fracture Toughness Properties of Line Pipes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: To investigate the mechanical properties of pipeline subjected to plastic deformation, tensile tests and crack-tip-opening displacement (CTOD) tests were conducted on X60, X65, and X80 line pipe ...
Modified Equation To Predict Leak/Rupture Criteria For Axially Through-Wall Notched X80 and X100 Linepipes Having a Higher Charpy Energy
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A method of predicting the leak/rupture criteria for API 5L X80 and X100 line pipes was evaluated based on the results of hydrostatic full-scale tests for X60, X65, X80, and X100 line pipes ...
Effects of Local Metal Loss on Deformability of Line Pipes Subjected to Compressive Load
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, the deformability of line pipe with local metal loss was examined. A full-scale experiment and a finite element (FE) analysis were carried out for line pipe with local metal ...
Determination of Conditional Probability of Dynamic Ductile Axial Crack Arrest for Conventionally-Rolled, Lower-Toughness Linepipe Materials
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents an analytical procedure to predict the conditional probability of dynamic ductile axial crack arrest within one pipe joint length for pipeline materials operating at temperature ...
Evaluation of Leak-Before-Break (LBB) Behavior For Axially Notched X65 and X80 Line Pipes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Leak-before-break (LBB) behavior was evaluated for two series of API 5L X65 line pipes and three series of X80 line pipes with various levels of Charpy V-notch (CVN) absorbed energy. Full-scale ...
