In the ordinary condenser, the tube sheet made of carbon steel and the copper heat exchange tube are used as coolers. When the medium to be used for the heat exchanger is corrosive, the weld between the tube sheet and the shell, the tube sheet and the replacement Corrosion and leakage often occur at the joints of heat pipes.

Corrosion of a Shell-and-Tube Heat Exchanger NACE Mar 17, 2013 · The shell side is cooling water and the tube side is the process stream in this heat exchanger. A metallurgical characterization was conducted on the carbon steel tubes to investigate the failure mechanism and provide recommendations for potential mitigation. Tubes and scales were characterized in terms of microstructures, morphologies and compositions. The tubes were found to suffer corrosion in the form of pitting corrosion on both the shell and tube
