Components of a Shell & Tube Exchanger
Shell & tube exchangers are a type of exchanger made from tubes for transferring heat between fluids at high temperatures.
In shell & tube heat exchangers, the heat transfer surface is provided by the tubes that give the exchanger its name. One fluid flows inside these tubes while the other fluid flows parallel or across the tubes within the shell. Therefore, heat transfer occurs at the tube surfaces. Shell & tube exchangers are preferred over gasketed or soldered exchangers in high pressure or temperature situations. Shell & tube heat exchangers can be used in all types of processes and come in various subtypes.
Shell & tube exchangers can be safely and easily applied to all these processes as desired. Thanks to the compensator used by our shell & tube exchanger process support team during the design and production stages, there is no expansion or heat loss during heat transfer. During the welding of shell & tube type exchangers, the process is carried out with professional tube placement techniques to achieve maximum efficiency from heat transfer.
What are the Components of a Shell & Tube Exchanger?
The components of shell & tube exchangers are as follows:
- Tubes that are straight or bent in a U shape to facilitate heat transfer
- The outer shell made from tubes or rolled sheet metal
- The tube sheets where the tubes are fixed
- Baffles that direct the flow outside the tubes within the shell and support the tubes
- Shell nozzles for the entry and exit of the shell side fluid
- Head and head nozzles for the entry and exit of the tube side fluid
- Flanges that secure the tube sheets and heads
- Support legs that can be used to mount the exchanger on a base
- Insulation to prevent heat loss from the exchanger's external surfaces
