Korozija u rashladnim sistemima
Destruction of heat exchangers
DP 'HIP - Azotara', Pančevo
Sažetak
Toplotni razmenjivači sa rashladnom vodom u instalacijama hemijske industrije perforiraju us led delovanja depozitne korozije i pitinga. Efikasnost inhibitora ove korozije se ocenjuje na osnovu krive polarizacije čelika i metalografskog snimka.
Abstract
Deterioration and destruction of heat exchangers in chemical industry which use cooling water as a cooling medium is due to the effect of the pitting and deposition corrosion. The efficiency of inhibitors can be established only by the polarization curve of steel and microstructure picture but not by measuring the rate of corrosion by loss of mass.
