ASTM A335 Steel grade P22 is widely employed for boiler tubing and steam piping in thermal power plants. Scale formation in internal surface of boiler tubes is one of the major problems in most of high-pressure boilers of thermal power stations. Two major problems result from deposit fouling on the interior tube surface: (1) Loss of heat transfer, and (2) Under-deposit corrosion. Therefore, it is necessary to clean, and mineral acids are typically employed for this purpose. The present study addresses the corrosion behavior of ASTM A335 P22 steel in hydrochloric and sulfuric acid solution at different temperature and agitation using different technique electrochemical. The relationship between the rate of corrosion on P22 steel and the temperature of the acid medium follows the Arrhenius kinetic model. The increase of the temperature and agitation of the acid medium produced on the surfa...
