The corrosion of steel reinforcement in an aging highway infrastructure is a major problem currently facing the transportation engineering community, in particular bridge engineers. In the United States, maintenance and replacement costs are measured in billions of dollars. Further, the use of deicing salts has resulted in steady deterioration of bridge decks due to corrosion. These concerns ha...
one of the most commonly used techniques to reduce the corrosion rate of rebar in concrete is addition substances named corrosion inhibitors into the concrete. corrosion inhibitor is chemical compounds that were added to concrete to prevent corrosion of steel in concrete. sodium nitrate is a type of anodic inhibitors that this study investigatesthe effect of this inhibitor on the properties of ...
Hydrocarbons are prone to bacterial and fungal contamination. Bacteria and fungi live and proliferate in water droplets within the fuels and on surfaces surrounding them. This can cause corrosion in oil exploration and production, clogging of fuel lines in aviation and higher emissions in diesel combustion engines to state few examples. State-of-the-art is the addition of biocides to fuels, whi...
Introduction Reliable estimates indicate that corrosion of metals costs the US economy almost $300 billion per year or about 4% of the GNP. Corrosion is a pervasive problem that affects almost all sectors of the economy including transportation (bridges, automobiles, aircraft, ships, pipelines, etc.), energy (power plants, petrochemical industries etc.) and defense (naval applications, aging ai...
LI, CHONG, Ph.D., June 2009, Chemical Engineering Effect of Corrosion Inhibitor on Water Wetting and Carbon Dioxide Corrosion In Oil-Water Two-Phase Flow (198 pp.) Director of Dissertation: Srdjan Nesic The internal corrosion of flowlines and pipelines made from carbon steel is encountered in the oil and gas industry. The corrosion process is primarily associated with the presence of free water...
