3. INTRODUCTION
 A shell and tube heat exchanger is one of the most
popular types of exchangers due to its flexibility.
 In this type, there are two fluids with different
temperatures, one of them flow through tubes and
another flow-through shell.
 Heat is transferred from one fluid to another
through the tube walls, either from the tube side to
the shell side or vice versa.
 This system handles fluids at different pressures;
higher pressure fluid is typically directed through
tubes, and lower pressure fluid is circulated through
a shell side.

SHELL
 The shell is constructed either from pipe up to 24
inches or rolled and welded plate metal. For
reasons of economy, low carbon steel is standard,
but other materials suitable for extreme
temperatures or corrosion resistance are often
specified.

Tube
 Tubes are generally made seamless or welded.
Seamless tubing is produced in an extrusion
process; welded tubing is produced by rolling a strip
into a cylinder and welding the seam.
 Tubes are made from low carbon steel, stainless
steel, titanium, Inconel, Copper, etc. Standard tube
diameters of 5/8 inch, 3/4 inch, and 1 inch

Tube sheets
 Tube sheets are made from a round flat piece of
metal with holes drilled for the tube ends in precise
location and pattern relative to one another.
 Generally, the tube sheet material is the same as
the tube material. Tubes are appropriately attached
to the tube sheet

Applications and uses
 The simple design of a shell-and-tube heat exchanger makes
it an ideal cooling solution for a wide variety of applications.
One of the most common applications is the cooling
of hydraulic fluid and oil in engines, transmissions
and hydraulic power packs. With the right choice of materials
they can also be used to cool or heat other mediums, such as
swimming pool water or charge air.There are many
advantages to shell-and-tube technology over plates
 One of the big advantages of using a shell-and-tube heat
exchanger is that they are often easy to service, particularly
with models where a floating tube bundle is available.(where
the tube plates are not welded to the outer shell).
 The cylindrical design of the housing is extremely resistant to
pressure and allows all ranges of pressure applications.
