LIMITATIONS OF PRECIPITATION AND CORROSIVELY INDICES IN THE COOLING WATER SYSTEMS

This paper explains the importance of measuring the precipitation and water corrosivity in cooling water systems. The limitations of Raisner and Langlier indexes have been explained. Then the benfits of Puchorius index in determining the precipitation and water corrosivity have been investigated. Finally, as a case study, the limitations of Raisner and Langlier indexes against Puchorius index have been discussed for the cooling water system of hot rolling of Mobarake Steel Complex.
