The Tube Sheet Heat Exchanger is the most common type of heat exchanger with numerous high temperature and high pressure applications. There is no chance of intermixing of fluids in this type of heat exchanger, which makes it ideal for various refinery services and other chemical industries. It consists of straight tubes secured at both the ends with welded tube sheets. It has a simple and compact structure that requires low cost. Further, the Tube Sheet Heat Exchanger can be easily removed from the channel cover and cleaned mechanically. It resists leakage due to the absence of flanged joints. It is suitable for applications where there is small difference between the tube and the shell.
