Finned tubes are used wherever electricity is generated or raw material is refined and efficient cooling is required. Finned tubes are used in condensers， coolers and furnaces. The larger surface area means that fewer tubes are needed compared to the use of plain tubes. The higher efficiency of finned tubes thus enables significant space and cost savings

What is a Studded Tube?
Studded tubes are a type of metal tubes. These tubes have studs welded onto the metal tube.
These studs are arranged in a specific formation throughout the length of the tube.
They are often used in boilers and refineries. As they increase the surface area for higher heat transfer they are used for reheating.
Features of a Studded Tube
- It occupies less space and is， therefore， compact.
- Highly durable.
- Preferred over Finned tubes as they act as heat transfer systems.
Uses of Studded Tubes
Steel studded tubes are used instead of finned tubes for heat transfer in the petrochemical industry， generally in furnaces and boilers where the surface is exposed to a very corrosive environment and where very dirty gas streams require frequent or aggressive cleaning.
