Microbiological-Influenced Corrosion Failure of a Heat Exchanger Tube of a Fertilizer Plant

  • Pankaj Sharma
Case History---Peer-Reviewed


The investigation was performed to examine the probable cause of failure of a heat exchanger tube at a fertilizer plant. Detailed metallographic analysis, chemical analysis, and microbiological culture tests were carried out to ascertain the cause/causes of failure. A detailed scanning electron microscopic analysis was a necessary supplement to this investigation. The results obtained indicate that pitting and fouling in a heat exchanger tube occurred due to microbiological-influenced corrosion.
