Shell and Tube Heat Exchanger Industrial Applications

- Jul 14, 2018 -

Advantages
•    Less initial cost.
•    Easy to find leaks (depending upon location).
 
Disadvantages
•    Large for capacity.
•    Capacity is fixed.
•    Difficult to clean.
•    Need a lot of space for overhauling.

Construction
Heat exchanger manufacturers typically construct their products, including steel, titanium, copper, bronze, stainless steel, aluminum or cast iron. One of the biggest problems with heat exchangers is corrosion, which is common due to the constant flow of liquid. Unfortunately, this is hard to avoid. To prevent this from happening, heat exchanger manufacturers need to be able to withstand general corrosion, pitting, stress corrosion cracking (SCC), selective leaching and oxygen cell erosion. It is also helpful that some heat exchanger designs contain fins to provide greater thermal conductivity.
 
Most plate type heat exchangers will have titanium plates, titanium is almost totally impervious to corrosion caused by seawater and guarantees a long life providing it is properly maintained.
 
Shell and tube heat exchangers are constructed from a mixture of copper, nickel, titanium, steel or aluminium depending on there applications. Each part may have different materials depending on what is flowing through it.
 
Different Applications of Heat Exchangers
Although they are not always known by the name "heat exchanger", these devices are very common and not always industrial. For example, a car's radiator is a useful device for transferring heat from the engine to the air. Other examples of commercial uses for heat exchangers include hot spring and pool heating, domestic radiators, hot water radiators, refrigerators and air conditioners. Whether for commercial or industrial use, heat exchangers are essential as energy and money-saving devices because most mechanical, chemical and energy systems require some type of heat transfer.

Custom heat exchangers perform a crucial role in the design, operation and maintenance of heating and air-conditioning systems, vehicle design, power plants, refrigeration, chemical and industrial engineering systems. They are also important in settings such as food processing, industrial engineer processes, pharmaceutical, pulp and paper and the steel industry. All power generation industries need them. Other industries that use heat exchangers include aerospace, chemical, marine, semiconductor, petrochemical, electronic, automotive, water treatment facilities and textiles.
