“…Ions, typically chlorides cause depassivation of the protective films lead to corrosion process. Process corrosion on rebar can be simplified by the following reactions Magdalena, 2016): In anodic site, there is reaction oxidation process on steel (Asmara et al, 2013;Asmara, 2011).…”

“…Rebar has serious corrosion problems when they are contacted with water, salt (NaCl) and carbon dioxide (CO2). In industrial areas where CO2,H2S, S and C are present, corrosive species are more complex which complicate corrosion mechanism Alia et al, 2017;Asmara et al, 2013;Asmara et al, 2011). Corrosion of rebar does not only damage concretes but also reduces concrete strength.…”

High requirements in protection of steel reinforcing bar (steel rebar) from corrosion are necessary since there are multi interaction of corrosive chemicals which cause early damage of concrete buildings. Corrosion of steel in concrete can destroy the concretes and reduce concrete strength. To protect rebar from corrosion, application of corrosion inhibitor is believed to have higher performance compared to other protection systems. To date, organic inhibitors have promising methods in steel rebar protection as they are environment-friendly, compatible with concrete, cost effective and applicable in any various concrete conditions. Thus, demands in using these inhibitors tend to increase significantly. This paper reviews the applications of green corrosion inhibitor specifically highlighted in protecting mechanisms, typical plants extracted, performance in corrosion protection, and classification of green corrosion inhibitors. The corrosion resistances of carbon steels in concrete protected by green inhibitors are in focus. As summary, it can be confidently notified that green corrosion inhibitors for steel in concrete will have a prospect to be used as corrosion prevention in the future with further improvements.

“…The process parameters of the failed sample show the presence of sulfides, carbide, and free sulfur, thus making it a complex system to predict corrosion rates [33]. A lot of research has been undertaken to understand the effect of H 2 S on the CO 2 system [34][35][36][37][38][39]. The corrosion process involves lots of complex combinations of reactions that affect the corrosion rates and film-forming rates.…”

Impact of Prolonged Exposure to Sour Service on the Mechanical Properties and Corrosion Mechanism of NACE Carbon Steel Material Used in Wet Sour Gas Multiphase Pipeline

The oil and gas industry is involved with severe corrosive/sour environmental conditions due to H2S, CO2, and moisture content. The National Association of Corrosion Engineers (NACE) has developed standards to enable users to select suitable materials for given sour conditions which utilize laboratory testing. A failed piping sample (API-5L-X65) was removed from a pipeline after 15 years of service. Optical microscopy was used to compare the microstructure of the corroded sample near the exposed surface to both the service environment, and further away from it. Moreover, pitted samples were analyzed using a scanning electron microscope coupled with energy dispersive X-ray (SEM/EDS) to understand the deposits’ morphology. Furthermore, XPS analysis proves the presence of a significant content of sulfur compound. Additionally, the mechanical properties of both corroded and non-corroded samples were evaluated and compared. Micro-hardness was carried out on the cross-section of the removed sample to understand any evident hardness variation from the inner diameter (ID) to the outer diameter (OD) of the piping. All the results suggest that prolonged service exposure has resulted in the development of micro defects, resulting in the reduction of strength and impact toughness, and the reduction in the hardness at the exposed surface of the corroded piping. Understanding the corrosion mechanism of pipelines exposed to sour media in the long-term helps in repair/replacement planning and extending the usable design life of the material, and paving the way for the oil and gas industry to develop additional ways to monitor the changes in the critical materials’ properties when exposed to sour service.

“…It can be seen that the results predicted by the model developed by Asmara et al (2013) deviated significantly from the experimental values when the time period was increased beyond 800 hours. Some of the models predict accurate results when they are predicting corrosion behaviour at low H 2 S concentrations (Sun & Nesic, 2007), while some of the other models predict accurate results at high H 2 S concentrations (Asmara et al, 2013). SSC-based research has been conducted for the materials which are used to manufacture oil country tubular goods (OCTG).…”

Sulphide stress corrosion (SSC) is an abundant type of corrosion in petroleum refineries. Steel pipes in petroleum refineries are influenced by the synergistic effect of tensile stress/pressure and high H 2 S concentrations in different environments. This paper focuses on the prediction of the propagation of depth of SSC in API 5L Grade B steel as a function of pH value, applied load, and time duration. The model has been established based on the experimental values of the depth of SSC under different predetermined test environmental conditions kept within the pH value of 2.7-3.5, an applied load of 400-800 N, and a time duration of 15-45 days. Further, the model was validated by another data set obtained for the depth of corrosion within the same aforementioned ranges of parameters. All the laboratory experiments were conducted in accordance with ANSI/NACE TM0177-2016 standard test methods. In addition, this paper discusses the microstructural observations of specimens kept under the aforementioned test environmental conditions. The scanning electron microscope (SEM) images of cross-sections of corroded specimens showed that crack initiation occurred after 15 days under all different test environmental conditions. Further, crack propagation occurred transversely, developing branches through the cross section until 30 days of time duration and the behaviour of the propagation of the crack was completely changed at 45 days of time duration.
