EBSD Study on Transverse Tensile X80 Grade Pipeline Steel
2010 8th International Pipeline Conference, Volume 2, 2010Transverse tension testing was carried out on an X80 grade linepipe to investigate the deformation behavior and the evolution of microstructure by means of SEM-EBSD (Electron Backscattered Diffraction) technique. Test results show that uniform elongation could achieve up to 7% in transverse tension for an X80 linepipe.

Recommendations on X80 steel for the design of hydrogen gas transmission pipelines
International Journal of Hydrogen Energy, 2012Abstract By limiting the pipes thickness necessary to sustain high pressure, high-strength steels could prove economically relevant for transmitting large gas quantities in pipelines on long distance. Up to now, the existing hydrogen pipelines have used lower-strength steels to avoid any hydrogen embrittlement.

Simulation of hydrogen diffusion in welded joint of X80 pipeline steel
Journal of Central South University, 2014Hydrogen diffusion coefficients of different regions in the welded joint of X80 pipeline steel were measured using the electro-chemical permeation technique. Using ABAQUS software, hydrogen diffusion in X80 pipeline steel welded joint was studied in consideration of the inhomogeneity of the welding zone, and temperature-dependent thermo-physical and ...

New Development of High Grade X80 to X120 Pipeline Steels
Materials and Manufacturing Processes, 2011An overview of the manufacturing technology for high-strength pipeline steels was introduced. The microstructure and mechanical properties of X80, X100, and X120 grade steel plates and pipes were analyzed and discussed. Through the UOE simulator, the changes of mechanical properties after pipe-forming from plate to pipe were evaluated.

Effect of a New Quinoline Inhibitor on Corrosion of X80 Pipeline Steel
Applied Mechanics and Materials, 2014The corrosion behavior of X80 pipeline steel with quinoline inhibitor in NACE solution (CO2 environment) at different temperature/different pH/different inhibitor volume fraction was researched using electrochemical test methods. The results show that as the temperature increases from 30°C to 50°C, CO2 corrosion of X80 pipeline steel becomes much ...
