What is meant by Shell and Tube? In Heat Exchanger,there is one most familiar type of exchanger is Shell and Tube Exchanger ,the designers are allow to use wide range of pressures and temperatures because of flexibility and compact. Shell and tube heat exchangers are basically used for the transfer of heat in industrial process applications. They are available in a variety of diameters and lengths.It is manufactured using the most advanced technology available and is specifically engineered for a wide range of applications. Every unit is designed, manufactured and tested to meet the quality requirements of the ASME code: Section VIII Division #1 and ISO 9002. There are two more categories 1. Petrochemical industry which tend to be covered by standards from TEMA 2. Power industry such as feedwater heaters and power plant condensers There are number of common features specified regarding type of industry exchanger.A shell and tube exchanger consists of a number of tubes mounted inside a cylindrical shell. There are two fluid exchange the heat one fluid flows over the outside of the tubes while the second fluid flows arrangementthrough the tubes. The fluids can be single or two phase and can flow in a parallel or a cross/counter flow arrangement Which Industries are used this Shell and Tube Heat Exchanger The Heat Exchanger using industries are as follows: 1.Waste water treatment 2.Refrigeration systems 3.Wine-brewery industry 4.Petroleum industry. 5.Marine Engineering. Advantage and Disadvantage of Shell and Tube Heat Exchanger Advantages 1. The Design of Shell and Tube Heat Exchangers is very Compact.
2. Its capable to handling with High Pressure.
3. Its less expensive too.
4. Can be used in systems with higher operating temperatures and pressures
5. Pressure drop across a tube cooler is less
6. Tubular coolers in refrigeration system can act as receiver also.
7. Using sacrificial anodes protects the whole cooling system against corrosion
8. Due to the pressure differential ube coolers may be preferred for lubricating oil cooling. Disadvantages: 1. It is very tough to readily analyze the shell side of the tubes for scaling or tube damage
2. Less efficiency in Heat Exchanger
3. Cleaning and maintenance is Problematic since a tube cooler requires enough clearance at one end to remove the tube nest
4. It cannot be increased the capacity of tube cooler.
5. Its require more space for drop it at one place.
