The tube sheet is one of the important parts of the heat exchanger, which is used to arrange the heat exchange tubes and plays the role of separating the tube side and the shell side space. The thin tube sheet has the advantage of saving materials and is used in medium and low pressure heat exchangers; the oval tube sheet is welded with the shell of the heat exchanger, and the stress conditions are better, and it is suitable for high pressure, large diameter heat exchangers .
