Summary: This study investigated the stress corrosion cracking (SCC) behavior of X100 pipeline steels with different heat-treated microstructures in carbonate/bicarbonate solution. The results showed that SCC susceptibility increased as the cathodic potential shifted. At a weak cathodic potential, hydrogen sensitivity controlled SCC behavior, while at a more negative potential, both electrochemical effect and hydrogen sensitivity influenced SCC behavior. The propagation paths of SCC cracks varied with the adjustment of the applied potential.

Summary: In this study, the corrosion and stress corrosion cracking (SCC) behavior of X65 steel in H2O-saturated supercritical CO2 (s-CO2) containing SO2 and O-2 impurities were investigated. It was found that X65 steels experienced severe corrosion and formed a porous corrosion layer composed of iron sulfates, carbonates and oxy-hydroxides. The mass loss of X65 steel increased linearly with exposure time in the s-CO2 environment. Timely replenishing s-CO2 fluid is crucial for accurately determining the long-term corrosion kinetics. Factors such as SO2 content, H2O content, and addition of NO2 were found to affect the long-term corrosion rate, which was described by a power-function-based empirical model.

Summary: Characterising the corrosion behaviour of pipeline steels in impurity-containing dense phase CO2 is crucial for cost-effective carbon capture and storage projects. Experimental studies have been conducted to predict and control corrosion using various testing methods. However, the reliability and reproducibility of published literature on corrosion rates are lacking due to challenges in controlling test parameters, highlighting the urgent need for a standard test method.

Summary: The study found that a liquid film with a thickness greater than or equal to 1 mm has no effect on the mechanism of the corrosion process, but has a control effect on the corrosion rate and the time of each stage in corrosion. The corrosion process can be divided into two stages: in the early stage, the concentration of ions inside and outside ADP is the same, so the corrosion is uniform; in the later stage, due to the influence of CO2 dissolution and mass transfer distance, the cathodic reaction is mainly outside ADP and the anodic reaction is mainly inside ADP. In addition, corrosion acidification occurs in ADP, which enhances the corrosion process in ADP.

Summary: In this study, the corrosion rates of natural gas pipeline steel X80 in a H2S/CO2 coexistence environment were investigated under different H2S/CO2 partial pressures, temperatures, and applied stresses. The results showed that the corrosion of X80 steel was more severe under pure CO2 condition than in the presence of H2S. The formation of amorphous Cr (OH)3 improved the corrosion stability of X80 steel in the H2S/CO2 coexistence environment. The corrosion rates of X80 steel increased with the increase of H2S partial pressure and temperature, while the applied stress significantly accelerated the corrosion process.

Summary: The SCC behavior of X80 pipeline steel was studied under the conditions of D. desulfurican, AC interference, and cathodic protection. The results showed that both AC interference and negative CP potential aggravated pitting corrosion and enhanced the SCC susceptibility under constant load. In the saline soil environment containing D. desulfurican, AC greatly contributed to the cracking tendency of X80 pipeline steel, resulting in a narrow safe CP range for practical engineering application, requiring appropriate discharge methods.

Summary: This study found that the susceptibility to stress corrosion cracking of API 5L X65 steel in CO2 corrosion medium increases with higher temperature and lower NaCl concentration. Additionally, in conditions of highest SCC susceptibility, anodic dissolution and hydrogen involvement were identified as the main SCC mechanisms through potentiodynamic polarization technique.

Summary: The paper investigates the stress corrosion cracking (SCC) behaviors of X100 pipeline steel in a carbonate/bicarbonate solution with varying chloride (Cl-) concentrations. It is found that the susceptibility of the steel to SCC increases with higher Cl- concentrations. Cl- promotes the SCC process by providing a high driving force for crack propagation and accelerating anodic dissolution, while also reducing FeCO3 content on the steel surface, which facilitates SCC initiation.

Summary: Experiments exposing ground 304 stainless steel samples to sea salt particles at different relative humidity levels showed that corrosion behavior varied significantly depending on the relative humidity of exposure. The distribution of pit populations, pit shapes, and increase in corrosion damage were all different between 40% RH and 76% RH conditions. These findings suggest that the mechanisms determining long-term corrosion behavior are different for different levels of relative humidity exposure.

Summary: This study analyzed the causes of leakage near the weld of an outdoor pressure pipe in a petrochemical plant using systematic characterization methods. It was found that the crack originated from the outside and extended to the inside surface of the pipe wall, with massive corrosion products on the crack surface. Furthermore, the damaged parts of the external insulating layer were wet and accumulated chlorine, indicating corrosive environment to the pipe material. It was concluded that the pipe leakage was due to the interaction of pitting corrosion, transgranular corrosion, and stress corrosion cracking.

Summary: This study investigates the microstructural transformation in the ICCGHAZ of X100 pipeline steel after a secondary thermal cycle and its hydrogen sulfide stress corrosion cracking (SSCC) resistance. The microstructure of the steel remains similar after the primary and secondary thermal cycles, with no significant impact on the crystallographic characteristics of the ICCGHAZ. An increase in t(8/5) leads to a decrease in SSCC resistance and more noticeable cleavage fracture characteristics.

Summary: In this study, the failure of a stainless steel component used in a hydrometallurgy plant's leaching reactor agitator was examined. The sample underwent various tests, including characterization of alloy composition, analysis of the work environment, and microscopic observation of the sample's surface and cross-section. It was found that the alloy had higher carbon content and lower nickel content than specified, which negatively affected its corrosion resistance. The working environment analysis revealed high concentrations of chlorides and sulfates, rendering even the specified alloy insufficiently corrosion resistant, particularly at a temperature of 90 degrees C. Microscopic examination identified intergranular corrosion and stress corrosion cracking as the primary failure mechanisms, with the presence of multiple CaSO4 inclusions accelerating the latter and allowing corrosive agents to penetrate the material.

Summary: The investigation revealed that the failure of a heavily cracked geothermal water convection tube was caused by stress corrosion cracking induced by chloride in the service environment and sensitization of the matrix. Additionally, residual stress arising from the manufacturing process also promoted the failure process.

Summary: A finite element model was developed to assess the interaction of internal and external defects on pipelines. It was found that external defects have higher maximum stress than internal defects, and pipelines with only external defects require a larger longitudinal spacing before interaction occurs.

Summary: Numerical models were developed to investigate the critical inclination of a pipeline to eliminate water accumulation at the floor of the pipe carrying oil-water fluid. Quantitative relationships were determined between the pipe inclination angle and factors such as flow velocity, viscosity, and pipe diameter, preventing water accumulation.
