Abstract
Corrosion researchers have developed many approaches to predicting the occurrence of different corrosion modes. Four types of predictive analytics can be identified: data-centric correlative analysis, theory-based semi-empirical models, expert-knowledge-based models, and theory-based, multi-scale models. However, most new corrosion failures have been serendipitous discoveries, rather than anticipated through a systematic process. This paper reviews stress corrosion cracking (SCC) of carbon steel in non-aqueous electrolytes and in aqueous solutions of oxyanions, to understand whether using the appropriate predictive analytic strategy may have helped anticipate the failures. In all of these cases of SCC, some information was available in related environments prior to field failures, but a framework was lacking to identify the connections and anticipate failures. Data-centric predictive analytics would not have helped anticipate the failures because of the low frequency of the phenomena and the lack of prior...

Abstract The environmentally assisted cracking behavior of carbon steel in various types of simulated fuel grade ethanol under low-frequency cyclic load and constant load conditions was investigated. In simulated fuel grade ethanol, carbon steel fractured under a low-frequency cyclic load condition, fatigue condition, but didn’t fracture under a constant load condition. Chloride promotes ethanol cracking under cyclic load condition. A decrease of the minimum load and an increase of the load freq...

The stress corrosion cracking (SCC) of carbon steel in nitrate-containing environments has been known for a long time and has become important in managing the integrity of aging underground radioactive waste storage tanks. This paper describes the latest research on the effect of environmental chemistry on localized corrosion and SCC of steel in nitrate-containing solutions, especially as it relates to radioactive waste storage systems. Nitrate is known to be an aggressive species for the locali...

Abstract A substantial amount of oil & gas products are transported and distributed via pipelines, which can stretch for thousands of kilometers. In British Columbia (BC), Canada, alone there are over 40,000 km of pipelines currently being operated. Because of the adverse environmental impact, public outrage and significant financial losses, the integrity of the pipelines is essential. More than 37 pipe failures per year occur in BC causing liquid spills and gas releases, damaging both property ...

AbstractAbu Dhabi Company for Onshore Oil Operations operates multiple carbon steel oil flow lines, which are emplaced on the desert surface of Abu Dhabi. The company's main oil pipelines are buried with coating and cathodic protection and internally protected by chemical inhibition, but the flow lines are without coating and cathodic protection. Over the years, this approach has been successful for flow lines, but the frequency of corrosion related leaks has increased recently due to changing o...

Abstract The influences of organic acids, chloride and water on the corrosion behavior of carbon steel in fuel grade ethanol (FGE) environments were investigated by immersion testing in simulated FGE. The roles of acetic acid, chloride and water in pitting corrosion were studied by using X-ray photoelectron spectroscopy (XPS), auger electron spectroscopy (AES) and electrochemical experiments. The results indicated that iron acetate is generated on oxide film. Iron(II) acetate shows high solubili...

The oil and gas industry heavily relies on the integrity of their pipeline systems and underground storage containers for economical and environmental reasons. The integrity of the pipeline systems and storage containers is largely threatened by localized corrosion. One of the primary forms of internal corrosion found in oil and gas pipelines, in addition to corrosion enhanced with carbon dioxide (CO2) and hydrogen sulfide (H2S), is microbiologically influenced corrosion (MIC). Biofilms are prod...

Corrosion processes mainly affect the probability of failure, which then leads to consequences, such as, fire, explosion, or environmental damage. This paper focuses on the use of Bayesian network models for assessing the probability of corrosion. The Bayesian network approach incorporates cause- effect relationships of complex systems in the form of conditional probabilities. This method considers both knowledge uncertainties (i.e., modeling uncertainties) and data uncertainties to make more in...

The reliability and risk of non-piggable, corroding oil and gas pipelines can be estimated from historical failure data and through reliability models based on the assumed or measured number of corrosion defects and defect size distribution. In this work, an extensive field survey carried out in an upstream gathering pipeline system in Southern Mexico is presented. It has helped determine realistic values for the number of corrosion defects per kilometer (defect density) and obtain a better desc...

Three in-service leaks on a crude oil pipeline operating in Canada were investigated to identify their metallurgical cause(s). The releases were found to be associated with cracks originating from the internal surface of the pipeline. Further similarities between the releases included: (1) the axial directionality of the cracks, (2) the short crack length, (3) the crack location adjacent to girth welds, (4) the circumferential location of the cracks and (5) the intergranular crack morphologies. ...

The increasing interest in renewable and cleaner fuels has stimulated ethanol production in the last decades. The most cost-effective solution to transport large volumes of it are pipelines. However, there is evidence that ethanol may cause stress corrosion cracking (SCC). This phenomenon can be assessed by slow strain rate tests (SSRT) using smooth and notched specimens. This work aimed to evaluate the API 5L X70 steel susceptibility to SCC in simulated fuel-grade ethanol (SFGE) through SSRT an...
