The Engineering Behind Shell and Tube Heat Exchangers and Their Benefits
Shell and tube heat exchangers are used for the flow of in-line heating and cooling. The innovative design allows the movement of fluids through the tubes and exterior shell delivering changeability. The movement of fluid can be run in a counterflow, cross flow, or parallel mode. The flow of the fluids can not be reversed, so the development of dirty pockets is then eliminated during the operation. Fluorotherm™ manufactures corrosion resistant products from PTFE, TFE, FEP, PFA, MFA and other materials. The unique design of Fluorotherm™ can be inspected, dissembled, cleaned, and repaired. The design also includes a material called fluoropolymer, which is known for its outstanding resistance to heat, up to 500°F continuously. Unimportantly is its usefulness in extremely cold temperatures. With little exceptions, fluoropolymer tubing can handle practically any corrosive chemical in use today.
The benefits of these Shell and Tube Heat Exchangers is a class of heat exchanger designs used in many processes, which has many variations within its own group. These advantages consist of the following:
- Easy maintenance and repair.
- They have no dimension limit.
- They can be used in all applications.
- They are resistant to thermal shocks.
- They have a very flexible and steady design.
- They can be designed and manufactured to handle extremely high pressures.
- Pressure loss is at a minimum and can be maintained at a minimum in line with the process objectives.
- They can also be designed and manufactured to handle extremely high and extremely low temperatures.
- The shell and heat Tube Exchangers can be easily taken apart and easily put back together for any maintenance such as cleaning and repair.
- The Pipes pitch, arrangement, length, number, and diameter can be modified. In other words, the designs of the shell and tube heat exchangers are very flexible.
Shell and heat tube exchangers are engineered so well to make it easy to pump materials as quickly as possible, while transferring temperatures efficiently keeping the materials at a required temperature without burning extra energy to do so. One of the greatest benefits of modern heat exchangers is that they do not rely on additional equipment like an air conditioning unit for example, to operate. They use less energy, (lower environmental impact) producing little to barely any pollution compared to other conventional methods. Finally, since heat exchangers do not use complicated equipment, they do not need to be maintained as often. They do not break down and can last a lot longer than other conventional units before needing any repair or replacement.
