Shell and Tube Heat Exchangers are one of the most popular types of exchanger due to the
flexibility the designer has to allow for a wide range of pressures and temperatures. There are two
main categories of Shell and Tube exchanger:
• Those that are used in the petrochemical industry which tend to be covered by standards from
TEMA, Tubular Exchanger Manufacturers Association (see TEMA Standards);
• Those that are used in the power industry such as feedwater heaters and power plant
condensers.
