Strain-Based Design Methodology of Large Diameter Grade X80 Linepipe [PDF]
, 2014 Continuous growth in energy demand is driving oil and natural gas production to areas that are often located far from major markets where the terrain is prone to earthquakes, landslides, and other types of ground motion. Transmission pipelines that cross

The International Journal of Multiphysics, 2013 Cet article présente une étude de la sensibilité à la fragilisation par l'hydrogène des joints soudés en acier API 5L X80 par les procédés SMAW et GTAW. En faisant varier les consommables utilisés et l'utilisation de la même température d'interpass, trois joints soudés différents ont été obtenus.

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.

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

Strain based design considerations for spiral welded pipelines [PDF]
, 2012 Pipelines are constructed in hostile environments where the occurrence of imposed plastic deformations can necessitate a strain based design approach. Under such conditions not only the strength and toughness properties have to be considered; also the ...

Study of the thermomechanical behavior of API 5L X80 steel micro-alloyed with Nb-Ti through hot torsion tests [PDF]
Rem: Revista Escola de Minas, 2015 The controlled rolling of high strength low alloy steel has been widely used in the production of large diameter pipes for the oil and gas industry. The thermo-mechanical control process (TMCP) is used to maximize grain refinement and achieve both higher strength and toughness in the steels.

, 2020 Aqueous extract of Thevetia peruviana leaves were investigated as corrosion inhibitor for API 5L X80 pipeline steel in 1M H2SO4 solution using electrochemical and gravimetric techniques. The results reveal that T. peruviana inhibited the X80 pipeline steel corrosion in the acid medium in a concentration dependent manner.
