Synthetically Modified Tara and Oak Gall Nut Tannin‐Based Corrosion Inhibitors for Combating the Corrosive Influence of Acidithiobacillus thiooxidans on Mild Steel

International Journal of Corrosion, Volume 2024, Issue 1, 2024.
Natural tara and oak gall nut tannins, which lack corrosion inhibitive properties, were modified using gum arabic and tested against microbial corrosion induced by Acidithiobacillus thiooxidans under isothermal condition (28°C). Mild steel coated with the modified tannins was exposed to the causative under aerobic and anaerobic conditions. Based on the

Carbon Dioxide Corrosion Mechanisms: Historical Development and Key Parameters of CO2‐H2O Systems

International Journal of Corrosion, Volume 2024, Issue 1, 2024.
The recent failures in flexible pipes have motivated the exhaustive research of corrosion mechanisms on high‐strength carbon steel armor wires that are the main structural compounds of those structures that mostly operate in seawater environments in the presence of carbon dioxide (CO2) and confined spaces.

Characteristic investigation of stress-hydrogen coupling hydrogen diffusion of X80 steel based on finite element simulation [PDF]

MATEC Web of Conferences
Since hydrogen atoms are enriched in the corrosion defect regions of steel pipelines under stress-induced effects when transporting gaseous hydrogen, this leads to the hydrogen embrittlement (HE) phenomenon.

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 ...
