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.
Used 3654.5 Sq Ft Energy Exchanger Company Carbon Steel Vertical Shell & Tube Heat Exchanger. Shell rated 240 psig @ 550 F, Tubes rated 240 psig @ 420 F, Type AEL, Size 49 x 144. (1551) Tubes x 3/4" ID x 14 ga x 12' Lg. Shell Dimension:4' 2 1/2" ID x 12' Lg. Lug Mounted, Serial #X-1168B, National Board #291, Built 1980. 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
