Lando manufactures shell and tube heat exchanger which suited to a wide range of operating conditions: heat exchangers with up to 3.5 meters in diameter, manufactured from steel or other materials (stainless steel, copper alloys, titanium, etc.)… Heat exchangers are devices that transfer energy, in the form of heat, from one working fluid to the next, whether that be solids, liquids, or gases. These devices are essential for refrigeration, power generation, HVAC, and more, and come in many shapes and sizes that can both introduce heat or remove it.
What is the Shell and Tube Heat Exchangers?
A shell and tube heat exchanger consists of a series of tubes housed within a cylindrical container known as a ‘shell’. All tubes within the shell are collectively termed a ‘tube bundle’ or ‘tube nest’.
It is the most common type of heat exchanger in oil refineries and other large chemical processes and is suited for higher-pressure applications. As its name implies, this type of heat exchanger consists of a shell (a large pressure vessel) with a bundle of tubes inside it.
Here is the article about what is the heat exchanger and types of heat exchangers to know more.
3 Types of Shell and Tube Heat Exchangers
There are 3 most common standard and popular models. The types are the U-tube, fixed tube sheet, and floating head heat exchangers.
Here show you the advantage and disadvantage of shell and tube heat exchangers :
- U-tube exchangers
1.The “U” shape exchangers with free-floating in the shell and has room to expand/contract.
2.Allows for thermal expansion to occur without implementing any kind of expansion joints
3. It is the best choice when using high-temperature differences and expansion.
The U tube bends are difficult to clean.
- The fixed tube sheet exchanger
1.the most cost-effective version of the shell and tube design
2.they are the easiest to manufacture
1. The temperature difference must be kept small to prevented expansion.
2.Must not foul the outside of the tubes, or the heat exchanger’s efficiency will decrease.
- The floating head exchanger
1. Combines the best aspects of both the previous designs
2. Allows the tubes to expand with increased temperatures, without needing to bend the pipes.
3. Easy to clean
1. Cost Higher
Application of the Shell and Tube Heat Exchangers
Heat exchangers have a number of industries in chemical plants. Following are some key application areas, where shell and tube heat exchangers are used:
- Power Generation
- Air Processing and Compressor Cooling
- Marine Applications
- Metals and Mining
- Pulp and Paper
We hope the information given above helps you get a better understanding of the shell and tube heat exchangers. This will help you in selecting the right type of heat exchanger based on your application requirements. When selecting a fabricator to manufacturer a heat exchanger look to an expert.
