Full‐scale testing of near‐neutral pH stress corrosion cracking growth behavior of a vintage X52 oil pipe

Fatigue &Fracture of Engineering Materials &Structures, Volume 47, Issue 5, Page 1638-1655, May 2024.
Abstract This study presents an experimental investigation conducted on a 40‐year‐old vintage X52 oil pipe segment to assess the growth behavior of near‐neutral pH stress corrosion cracking (SCC). Six cracks were introduced on the pipe specimen, each of which was associated with a unique combination of metallurgical and environmental condition.

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.
