A shell and tube heat exchange is a class of heat exchange designs. It is the most common type of heat exchange in oil refineries and other large chemical processes, and is suited for higher-pressure applications.
Heat exchange tubes are intended for heating or cooling process fluids, they are for example suitable for closed circuit cooling of electrical equipment using demineralised water and for cooling water soluble oil solutions in quenching tanks.
Sunny Steel supply a 1/2 million foot inventory of carbon steel pressure tubing including boiler tubes, condenser tubes and heat exchanger tubes all made in the China.

Here are a few of the most common types of heat exchangers that you will hear about:
The possible flexibility in design of these exchangers is mainly responsible for their wide use in a range of applications. These exchangers do not have design limitations in terms of temperature and pressure. These exchangers are easy to maintain. These exchangers can be easily designed to accommodate thermal stresses.
A shell and tube heat exchanger is a class of heat exchanger designs. It is the most common type of heat exchanger in oil refineries and other large chemical processes, and is suited for higher-pressure applications.
- Shell and Tube Heat Exchanger:
In a shell and tube heat exchanger, two fluids at different temperatures flow through tubes. One set of tubes is outside, and one is in the shell of the unit. Heat is transferred through the tube walls. The fluid in the tubes can be in liquid or gas form. A one phase unit is used for only heating or cooling, while a two phase can be used for both. - Air to Air Heat Exchanger:
These exchangers work to heat, cool or refresh the air in a space. - Water to Water Heat Exchanger:
A water to water heat exchanger continually cycles hot or cold water through tubes to heat or cool it again before sending it in the other direction. - Air to Water Heat Exchanger:
Water runs through tubes that are cooled or heated by a stream of air running over them. - Gas to air heat exchanger:
In a gas to air heat exchanger, heat created by gas flows upwards and is then pushed out of the exchanger’s exhaust.
This list is by no means exhaustive, but these five types of heat exchangers can be found in many buildings and commercial facilities. We’ll help you find the replacement parts and heat exchanging units that you’re looking for, whether they’re for units like the ones on this list or not.
