             Root Cause

            Carbonic acid corrosion due to presence of CO2/H2O in the gap between flange and gasket.


             Recommendations

            1.  Weld to be buildup and surface finishing to be done in crevice of flange.
            2.  Flange to be kept end blinded to minimize dead zone.

            3.  CS Flange to be replaced with SS.
