Tubes of the heat exchanger will be held on
both the sides by Tube sheets. Tubes will be
inserted through holes provided on tube
sheets. Tubes are firmly fitted in the tube
sheet either by welding or by mechanical or
Baffles are provided to support the tubes,
to maintain the space between the tubes and
it also channelized the fluid flow as per
design through the shell side of heat
Tie Rods and Spacers
Tie rods and spacers will hold the baffle
assembly together; and will also maintain
the spacing between the baffles. One end of
the tie rods are
secured to the tube sheet and other ends are
secure in the last baffle.
Channels or heads are provided for
shell-and-tube heat exchangers to contain
the tube side fluid and to provide the
desired flow path.
Application of Shell and Tube Exchanger
Shell and tube heat exchangers are used as
condensers, re-boilers, process heaters,
coolers and falling film evaporator.
