Types of finned tube heat exchangers.
When the tubes are manufactured, they go through a corrosion protective process to strengthen it against the failure caused due to corrosion! Some fin tube types are:
1. ‘L’ Fin Tubes
They can work at a maximum temperature of 150 degrees Celsius.
It has an acceptable level of atmospheric corrosion resistance.
It is made of aluminium and copper.
Offers a poor mechanical resistance.
2. ‘LL’ Fin Tubes
They can work at a maximum temperature of 180 degrees Celsius.
It has an acceptable level of atmospheric corrosion resistance.
It is made up of aluminium and copper.
Offers a poor mechanical resistance.
3. ‘KL’ Fin Tubes
They can work at a maximum temperature of 260 degrees Celsius.
They have an acceptable level of atmospheric corrosion resistance.
They are made up of aluminium and copper.
Offers acceptable mechanical resistance.
They can work at a maximum temperature of 400 degrees Celsius.
They have a poor level of atmospheric corrosion resistance.
They are made up of carbon, aluminium and copper.
Offers acceptable mechanical resistance.
They can work at a maximum temperature of 285 degrees Celsius.
They have an excellent level of atmospheric corrosion resistance.
They are purely made up of aluminium.
Offers excellent mechanical resistance.
