This study demonstrates that a 1.48 wt% Ni addition to the welding wire effectively counteracts these detrimental effects in X65MH steel welds. The Ni-alloying strategy engineers a synergistic toughening microstructure characterized by a 12.21 % reduction in average grain size due to the promotion of fine acicular ferrite, and a 55.6 % increase in retained austenite, which serves as a beneficial hydrogen trap. Furthermore, Ni refines the grain boundary network, increasing the density of low-angle grain boundaries to create a more tortuous diffusion path for hydrogen. It also significantly reduces dislocation density (average Kernel Average Misorientation value decreased by 22.14 %) and induces a shift in martensite morphology within Martensitic-Austenitic(M-A) constituents from lath to twinned type. Crucially, transmission electron microscopy confirms that these enhancements stem from solid solution effects and modulated phase transformation kinetics, not precipitation strengthening. Consequently, the Ni-alloyed weld exhibits superior performance: the hydrogen embrittlement susceptibility index is reduced by 10.8 %, and the impact toughness loss rate after 48 h hydrogen charging decreases from 12.6 % to 10.1 %.

This study introduces a validated thermo-hydraulic simulation framework that incorporates In-Line Inspection (ILI) data to assess TLC risks and support monitoring-based mitigation strategies. Numerical modeling of three operational 32-inch pipelines demonstrates that temperature exerts a greater influence on sour TLC than water condensation. Pipelines A and B, with inlet temperatures of 60–70 °C, exhibited no corrosion near the inlets despite high condensation rates, which is attributed to the stability of protective FeS films. Severe TLC occurred downstream, with up to 20 % wall loss after 4.5 years, where wall temperatures decreased to 30–55 °C. Pipeline C, operating at a 56 °C inlet temperature, experienced immediate TLC, confirmed by ILI data, up to 12 % wall loss. The study identifies a critical threshold of 0.4 mg/L water content for corrosion initiation. The model facilitates monitoring by creating corrosion susceptibility maps, risk-based inspection schedules, and highlighting areas prone to TLC. Recommended mitigation methods include maintaining isolations, deploying vapor-phase inhibitors when isolations are not feasible, and prioritizing inspections in segments where conditions exceed critical thresholds. This integrated modeling and inspection approach provides a quantitative basis for predictive TLC management and improved pipeline integrity programs.</div></div>","PeriodicalId":290,"journal":{"name":"Corrosion Science","volume":"258 ","pages":"Article 113371"},"PeriodicalIF":7.4,"publicationDate":"2025-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145219456","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
