... with oxygen, high temperatures, high level of chlorides, pH, chemical injection, use of water and method of regenerating the solvents. These solvents decomposition products are acidic in nature that will results in serious corrosion issues in carbon steel and stainless-steel material in the form of pitting...

... absorbers and associated rich amine piping particularly around the welds, downcomers and other turbulent locations are particularly vulnerable. In extreme circumstances, there has also been evidence of blistering, HIC cracking and widespread pitting in such steels. This paper will discuss case histories...

... damage combined with the high levels of iron oxide detected in the scales/deposits and corrosion products at the pitting sites strongly indicate that corrosion on the pipe was exacerbated by the formation of concentration cells as shown in Table 4 . Table 4 Sample B, EDS Map Sum Spectrum Element...

... inhibitors (batch and continuous) to protect carbon steel surfaces from localized corrosion (pitting). The first part of this study proved out the good correlation between the results obtained with electrochemistry methods and the long-term immersion/autoclave testing. General corrosion rates from weight...

... with higher potential than iron, which might increase the severity of the corrosion. Also, corrosion product layers were analyzed and causes of these failures were approached. Flow accelerated corrosion Heat recovery steam generator Pitting Desalination plants Economizer tubes Boiler feed water...
