| Abstract: | The localized corrosion and corrosion failure occurred in the tubes of E104 vaporizer overhead sea water cooler in continuous catalytic reformer in Dalian Petrochemical Company. The corrosion analysis by physical examination techniques showed that the corrosion was mainly caused by Cl - in the sea water. After the selection of 10CrMoAl low alloy for the tubes in sea water corrosive environment and selection of 08Cr2AlMo or 09Cr2AlMo low alloy steels for the sea water and H 2S environment, good results have been obtained. |
