They are often easy to service, particularly with models where a floating tube bundle (where the tube plates are not welded to the outer shell) is available.
Can also be used on fixed tube sheet heat exchangers.  
 
 
Typical applications 

1. Process liquid or gas cooling
2. Process or refrigerant vapor or steam condensing
3. Process liquid, steam or refrigerant evaporation
4. Process heat removal and preheating of feed water
5. Thermal energy conservation efforts, heat recovery
6. Compressor, turbine and engine cooling, oil and jacket water 
7. Hydraulic and lube oil cooling

Advantages
 1.Less expensive as compared to other type coolers.
2.Can be used in systems with a wide range operating temperatures and pressures.
3.Pressure drop across a shell and tube heat exchangers is less.
4.Tube leaks are easily located and plugged since pressure test is comparatively easy.
5.Tubular coolers in refrigeration system can act as receiver also.
6.Using sacrificial anodes protects the whole cooling system against corrosion.
7.Extended heat transfer surfaces (fins) can be used to enhance heat transfer.
8.Cleaning and repair are relatively straightforward, because the equipment can be dismantled for this purpose
9.The heat exchanger has two type including horizontal and vertical styles, so it can be installed in different locations conveniently.
