Résumé : |
Corrosion is the destruction of metals by interaction with the environment. It is part of a natural cycle of events, in which metals tend to return to the state in which these are present in the earth. The implications of metallic corrosion are far-reaching:loss of metal thickness and mechanical properties, loss of production through corroded pipelines, contamination of product, undesirable blockages of valves and pipelines, reduction of heat transfer, shut-down of plants and, sometimes, loss of human lives. The cost to the national economy as a result of corrosion has been shown to be stupendous. It has been estimated that U.S.A., spends as much as 10 billion dollars annually on corrosion control, U.K., to the extent of £800 million and India Rs. 1500 million. While it is not possible to give a precise estimate of the cost of corrosion control in circulating water systems, it has been indicated that on corrosion inhibitors alone, USA, is spending 50 million dollars annually and the expenditure incurred in a single oil refinery can be as much as 100,000 dollars. |
