Preliminary Evaluation of the Influence of Hydrogen on the Fracture Toughness of an X65 Gas‐Transmission Pipeline Steel [PDF]
Advanced Engineering MaterialsPrevious research has indicated that hydrogen decreases the fracture toughness of gas‐transmission pipeline steels. This study produced two values of fracture toughness for the X65 steel in the Dampier Bunbury natural gas‐transmission pipeline in air (JQ of 590 and 778 kJ m−2; equivalent to KQ of 369 and 487 MPa) and two essentially American Society ...

Materials and CorrosionABSTRACTThis study investigated the effect of subcritical heat treatment and cold work on the hydrogen embrittlement (HE) susceptibility of the X65 D pipeline steel, representative of the Dampier‐Bunbury Natural Gas Pipeline (DBNGP). Specimens were subjected to sub‐critical annealing at 200°C, 400°C, or 600°C for 2 h or cold drawn to 5% reduction in ...

Investigating electrochemical charging conditions equivalent to hydrogen gas exposure of X65 pipeline steel [PDF]
Materials and Corrosion, Volume 75, Issue 3, Page 315-321, March 2024., 2023 Relating gaseous and electrochemical hydrogen charging can ease the evaluation of repurposing pipelines for hydrogen gas transport. In this study, the equivalent hydrogen pressure was investigated using gaseous and electrochemical hydrogen permeation. The hydrogen recombination poison concentration and the applied potential are systematically changed ...

Preferential weld corrosion of X65 pipeline steel in flowing brines containing carbon dioxide [PDF]
Corrosion Engineering, Science and Technology, 2011 The aim of this research was to investigate the cause of the severe localised corrosion that sometimes occurs at welds in carbon steel pipelines carrying hydrocarbons and inhibited brines saturated with carbon dioxide. A rotating cylinder electrode apparatus was designed so that electrodes machined from the weld metal, heat affected zone and parent ...

Damage and Failure in an X65 Steel Pipeline Caused by Trawl Gear Impact [PDF]
Volume 2B: Structures, Safety and Reliability, 2013 Offshore pipelines subjected to accidental impact loads from trawl gear or anchors may experience large global deformations and large local strains, creating a complex stress and strain history. In this study experiments and numerical simulations have been carried out to investigate the impact of a pipeline which is subsequently hooked and released ...
