Effect of Glutaraldehyde on Corrosion of X80 Pipeline Steel [PDF]
Coatings, 2021 Glutaraldehyde (GA) is widely employed as a biocide to control microbiologically influenced corrosion in oil fields and industrial water treatment. It might be corrosive to metal. In this study, the effect of glutaraldehyde on the corrosion behavior of X80 pipeline steel was investigated using electrochemical measurement, weight-loss tests and scanning

Quantification of Splitting in X80 Pipeline Steel
Volume 3: Operations, Monitoring, and Maintenance; Materials and Joining, 2018The results of in-depth analysis of microstructure and crystallographic texture of several industrial batches of line pipes with known full-scale burst test results are presented. Several microstructural features promoting splitting are highlighted and quantified using electron back-scattered diffraction (EBSD) data.

Hydrogen induced cracking of X80 pipeline steel
International Journal of Minerals, Metallurgy, and Materials, 2010The hydrogen-induced cracking (HIC) behavior of X80 pipeline steel was studied by means of electrochemical charging, hydrogen permeation tests, tension test, and scanning electron microscopy (SEM). The experimental results indicate that the increase of charging time and charging current density or the decrease of the solution pH value leads to an ...
