Corrosion failure analysis of a perforated F32 reactor

Abstract The principle reason for corrosion failure because of perforation on a fluorination reactor was analyzed by chemical composition tests, microstructure and corrosion products observation tests in combination with the investigation of the working conditions of the reactor. The results show that a certain amount of complex inclusions containing MnS in the failure parts – are the principle cause of perforation. The relatively poor condition of the middle of the reactor, resulting in particular from excess hydrogen fluoride, is another principle cause.
