Double Tube Sheet Shell and Tube Heat Exchangers
In design of double tube sheet heat exchangers, in each side, two tube sheets are used which cause to prevent cross contamination of shell side and tube side fluids.
These heat exchangers are used in cases that cross contamination of two side fluids are dangerous and not tolerable.
In a double tube sheet heat exchanger design, a second outer tube sheet is added to further seal and separate the tubes and the shell. In a double tube sheet design, a second outer tube sheet is added to further seal and separate the tubes and the shell. The gap between the tube sheets allows for differential radial thermal expansion, minimizing stress on the tube-to-tube sheet expansions. The gap also allows for easy leak detection. double tube sheet heat exchanger are essential in applications where fluids cannot mix.
