Corrosion Inhibition of Steel by Triazolidines in Saline Water

As seawater is a complex, delicately balanced solution of many salts containing living matter, suspended silt, dissolved gases and decaying organic material, it is important to separate the effect of salts from the other factors to emphasize the corrosion rate due to the salinity. Salinity is defined as the total weight in grams of solid matter dissolved in 1,000g of water. The relative proportion of salts does not vary appreciably in interconnected seas. Variations in salinity in open-ocean surface water typically range from 32-37.5 per cent. In open circulating systems, sea water may be used as industrial cooling waters, particularly for industry located at the coast. New technologies using non-toxic organic instead of inorganic chemicals as corrosion inhibitors are advanced and have been introduced successfully in cooling waters treatment.
