Passivation process of X80 pipeline steel in bicarbonate solutions
International Journal of Minerals, Metallurgy, and Materials, 2011The passivation process of X80 pipeline steel in bicarbonate solutions was investigated using potentiodynamic, dynamic electrochemical impedance spectroscopy (DEIS), and Mott-Schottky measurements. The results show that the shape of polarization curves changes with HCO 3 − concentration. The critical

Steel cleanness requirements for X65 to X80 electric resistance welded linepipe steels
Ironmaking & Steelmaking, 2003AbstractIn Australia, a large proportion of the gas pipelines traverse rural areas of low population density with considerable distances between population centres. As these pipelines transport non-sour gas, there have been considerable economic advantages to be gained from the use of thin walled, small diameter, high strength linepipe grades.

Effect of Pipe Body Alloy on Weldability of X80 Steel
2015Effect of Mo, Ni, and Cr on impact property of pipe seam and heat-affected zone (HAZ) of X80 steel was investigated by thermal simulation test and butt welding test. The results showed that, there was an obvious relationship between strip’s composition and the toughness of weld and HAZ, the more content of Mo, Ni and less of Cr in the strip matrix, the
