“…From the examples given in the section on stress corrosion, the cracks discussed in several publications were intergranular (Turissini et al, 1997;Guo et al, 2011;Corleto & Argade, 2017). Intergranular cracks (without the application of stresses) were found in the cases discussed by Ifezue and Tobins (2015) (together with pitting) and Chandra et al (2010).…”

“…This acid, in combination with internal stresses in the bend, induced the cracks in the metal (type 321 steel), shown in the photograph of Figure 9. Several other examples of stress corrosion causing the failure of heat exchangers can be found in the literature for both shell-and-tube heat exchangers (Otegui & Fazzini, 2004;Guo et al, 2011;Qu et al, 2011;Ravindranath et al, 2012;El-Amoush et al, 2014;Corte et al, 2015;Xu et al, 2015;Corleto & Argade, 2017) and plate heat exchangers (Turissini et al, 1997;Traubert & Jur, 2012;Khodamorad et al, 2016). For two of these cases, it concerns corrosion fatigue (Otegui & Fazzini, 2004;Ravindranath et al, 2012), while in the others, SCC was the main cause of failure.…”

In many industries and processes, heat exchangers are of vital importance as they are used to transfer heat from one fluid to another. These fluids can be corrosive to heat exchangers, which are usually made of metallic materials. This paper illustrates that corrosion is an important problem in the operation of heat exchangers in many environments, for which no straightforward answer exists. Corrosion failures of heat exchangers are common, and corrosion often involves high maintenance or repair costs. In this review, an overview is given of what is known on corrosion in heat exchangers. The different types of corrosion encountered in heat exchangers and the susceptible places in the devices are discussed first. This is combined with an overview of failure analyses for each type of corrosion. Next, the effect of heat transfer on corrosion and the influence of corrosion on the thermohydraulic performances are discussed. Finally, the prevention and control of corrosion is tackled. Prevention goes from general design considerations and operation guidelines to the use of cathodic and anodic protection.

“…It was concluded that fluid-induced vibration in the tube bundle resulted in the fatigue damage of titanium tube-to-tubesheet joints. The fracture of welded 0Cr13Al stainless steel tube bundle in condensate/heavy gas oil (HGO) heat exchanger in a petrochemical plant was studied to investigate the failure mechanism [14]. The chemical composition, elements distribution and the morphology of the cracks were analyzed.…”
