Study on Corrosion Perforation Leakage Failure of Tube Bundle in High Pressure Air-cooled Heat Exchanger

Failure analysis of tube bundle in the high pressure air-cooled heat exchanger of the hydrogenation unit was conducted by means of chemical composition analysis,microstructure observation,mechanical properties test,corrosion product analysis and so on,and also drawing support from the computational fluid dynamics software fluent to simulate the main corrosion part of the tube bundle par.The results showed that the high pressure air-cooled heat...
