“…API 5L X65 API 5L X65 is an economical material and is considered safe for transporting oil and gas. This material combines hardness and strength to support high internal pressures in constructing high-pressure transport pipelines [14]. Highstrength low-alloy steel (HSLA) is used as a material for the petroleum industry and has favorable material characteristics [15].…”

The world's oil and gas sectors are diverse. They utilize offshore pipes to generate millions of barrels of oil and gas to meet global energy demands. In this study we identified the critical buckling load that occurred on a cylinder shell (also known as radial buckling). Offshore pipe design must meet several criteria, one of which is the requirement for pipes to withstand the external hydrostatic pressure of seawater. The overall buckling load is calculated using the axial compression loading and the pressure on the entire surface of the cylinder shell (radial compression). The finite element analysis (FEA) method is used in our simulation. FEA is run using ABAQUS/CAE software with the Riks algorithm. Different types of cylinder shells are used in the simulation: unstiffened, stringer-stiffened, and ring-stiffened. The cylinder shell is loaded based on the depth of the installation. The material composition of the shell is varied with API 5L X65, copper-nickel alloy, and HY100 steel. The diameter sizes used are 28" (711.2 mm), 30" (762 mm), and 32" (812.8 mm). The simulation results show a critical buckling load for each variation. The critical buckling load is determined by the Young's modulus, geometric length, and moment of inertia. Based on the critical buckling loads generated, we also identify which cylinder shell composition is the strongest.

“…The authors emphasize the importance of selecting the substituent group in the C 2 position of the imidazolines. In order to extend the understanding of the effect of the substituent groups on CIs with heterocyclic compounds, the same authors analyzed four oxazolidines for API X60 steel in 1 M HCl: 44 1-oxa-4-azaspiro [4,4]nonane (OXA1), 1-oxa-4-azaspiro [4,5]decane (OXA2), 6-methyl-1-oxa-4-azaspiro [4,5]decane (OXA3), and 1-oxa-4azaspiro [4,7]dodecane (OXA4). In the results of the electrochemical tests, the following IE trend was observed: OXA2 (53%) < OXA3 (67%) < OXA1 (75%) < OXA4 (82%).…”

“…Other types of heterocyclic compounds, such as quinazoline and benzopyranones/indole, have been considered as CIs by different authors. Aldana-Gonzaĺez et al 48 performed the analysis of the inhibiting properties of 2-bromo-6(2′,6′dichlorophenyl)dihydrobenzo [4,5]imidazo [1,2c]quinazoline for API 5L X52 steel in 0.5 M HCl by EIS, finding IE max of 94% from 15 ppm and suggested that the CI adsorption prevented the Faradaic processes that take place on the metal surface. Afterward, the study was extended independently with respect to the temperature and flow, where the temperature increase favored the molecule desorption process.…”

“…Ground grid is one of the critical protective equipment for the safe operation of transformer substation. Ground grids experience soil corrosion and many factors, such as soil resistivity, pH, temperature, moisture content and chemical composition of soil, play important roles in their corrosion process (Fu et al, 2013;Liu and Cheng, 2017;Oliveira et al, 2018;Zhu et al, 2020), which weakens their service performance and causes serious economic losses (Feng et al, 2010;Fu et al, 2013). For example, a large power outage happened in the USA and Mexico in September 2011, resulting to $118m of economic losses for the San Diego (Mao et al, 2012).…”

Purpose High-silicon chromium iron (HSCI) has been used in ground grids in southern China, while there was a lack of study on its corrosion behavior in this soil environment. The purpose of this paper is to discover the corrosion of HSCI in acidic and alkaline soil solutions. Design/methodology/approach The original defects on the HSCI surface were observed using optical microscopy, and the corrosion behavior of the HSCI in the acidic and alkaline soil solutions were jointly detected using electrochemical measurements and scanning electron microscopy/energy dispersive spectrometer. Findings The results showed the corrosion rates of the HSCI in the acidic and alkaline soil solutions were limited, and the high contents of Cr and Si in matrix was responsible for its high corrosion resistance. The HSCI showed a similar corrosion tendency in the two solutions, while its corrosion rate in the acid soil solution was higher than that in the alkaline soil solution. The corrosion pits on the specimen surface were originated from the original defects in matrix, and the edges of the corrosion pits were more rounded than the original defects after 720 h immersion in the two solutions. The original defects in the HSCI matrix played a significant role in the corrosion process. Originality/value The paper discovered the corrosion evolution of HSCI in the acidic and alkaline soil solutions. What is more, the acceleration role of the original defects on the corrosion of the HSCI in the acidic and alkaline soil solutions was discovered in the paper. The results are beneficial for the material selection of ground grid equipment in engineering.
