Shell and Tube heat exchangers

There are many different types of shell and tube (tubular) heat exchangers. Many variables in your process environment such as pressure, temperature, type of media, and cleaning requirements impact the optimal design of your heat exchanger.

 

 

 

The heat exchanger can be designed for single or several compartments both on the tube and the mantle side. The use of several compartments provides a higher flow speed and/or a shorter length.

 

The tubes are welded and/or rolled in one or two tube plates and are supported by a number of baffles. The purpose of baffles is to control the flow so that optimal speed and turbulence is maintained, and also so that vibrations are avoided in the tube.

 

The temperature difference between the tube and the shell side can lead to thermal strain. At higher temperature differences, the heat exchanger is often equipped with a compensator, which absorbs such tension.

 

If the heat exchanger is frequently subject to large temperature variations, the compensator will wear out, and in such cases, a U tube exchanger would be more suitable. This type of heat exchangers could also be beneficial in case of extremely high pressure or if shell side fouling calls for regular cleaning operations.

 

Our mechanical design comply with TEMA's recommendations.
