Floating Head Type Shell and Tube Heat Exchanger NACE, HIC, SSC, ASME VIII DIV.1

One end of the tube plate at each end of the floating head heat exchanger is fixedly connected to the shell by a flange, called the fixed end. The other end tube sheet is not connected to the shell, but can slide relative to the shell, this end is called floating head end. Since the floating head is located inside the shell, it is also called an internal floating head heat exchanger.
