Abstract

Heat exchanger is a device which is used to transfer heat from one medium to another. When the tubes fail, the reliability of heat exchanger is affected. This paper investigates the probable causes of failure of the tube reboiler sour water stripper in a heat exchanger. In that context, visual observation, dimensional measurement, mechanical testing, metallographic examination, and chemical analysis are conducted as part of the investigative studies. Finally, it has been concluded that the tube has mainly failed due to sulphide stress corrosion cracking.
