Heat exchangers are parts of industrial equipment that are deftly designed for facilitating the process of exchanging heat from one fluid(liquid or gas) to another fluid(liquid or gas). The purpose or the objective of heat transfer could be either for heating or cooling the elements of the fluids. The essential feature of the heat exchanger is that heat transfer occurs without the need of bringing the two fluids together. In industrial plants and factories, heat exchangers are widely used to keep the machinery, chemicals, gas, and other substances within a safe operating temperature.
There are different types of heat exchangers available in the market that employ different setups, equipment, and design features. While all the heat exchangers operate on the same principle, they work in different ways. Shell & Tube Heat Exchangers is one of the most commonly used heat exchanger widely used in industrial process applications like in refineries and chemical industries. Consisting of a sealed shell and a number of metal tubes, these heat exchangers are specifically designed to exchange heat flow between two fluids in enormous quantities.
How does it Work?
The two fluids of different temperatures are made to pass through the heat exchanger, where
one fluid flows through a set of metal tubes, the other fluid passes through a sealed shell that surrounds them. The heat transfer takes place between the fluids through the tube walls. The fluids can be either liquids or gases.
Shell and tube heat exchangers are used in various industrial applications due to their expertise in performing tasks such as:
- Cooling of hydraulic and lube oil
- Condensing process vapor or steam
- Cooling of turbine, compressor, and engine
- Evaporating process liquid or steam
What are the Advantages of Shell and Tube Heat Exchangers?
The equipment is highly preferable by the industrial units due to its robust structure and its ability to transfer a huge amount of heat at a relatively lower cost. Moreover, the shell and tube heat exchangers provide sufficient and effective tube surface that minimizes the requirements of floor space and liquid volume.
- Suitable for systems with higher operating temperatures and pressures.
- Any leaks in the tubes can be easily detected and fixed.
- Tubular coolers in the refrigeration system can also serve as a receiver.
- Sacrificial anodes can be used to protect the entire cooling system against corrosion
There are many Heat Exchanger Suppliers in the market that are offering different types of heat exchangers-varying in capacities and functioning. Praj Industries is one of the leading Heat Exchanger Suppliers offering Critical process systems and equipment to several processing industries. Over the years they have successfully catered to the demands of numerous companies and have made their mark in the industry.
