Effects of Alloy Content on Impact Toughness in X80 Pipeline Steel [PDF]
Proceedings of the 2015 2nd International Forum on Electrical Engineering and Automation (IFEEA 2015), 2016 The X80 pipeline steel for the west to east gas transmission project was successful produced, based on the hot strip mills equipment advantage. However, the impact toughness was unstable during the production. In this research, optical microscope, scanning electron microscopy (SEM) and energy dispersive analysis (EDS) test were used to study the ...

Design of a (mini) wide plate specimen for strain-based weld integrity assessment [PDF]
, 2011 Wide plate tension tests are commonly executed to investigate the integrity of defective welds under a uniaxial load. The specimen can be flat or curved, depending on the geometry from which it has been extracted (plate or pipe).

Innovative analysis of Luders band behaviour in X80 pipeline steel
Materials Science and Engineering: A, 2017 Abstract In this study, the influence of Luders bands, which are frequently observed after the pipe coating process, is investigated. Stratified tensile test specimens, machined from different locations across the thickness of an X80 line pipe, were tested.
