What is studded finned tube?
Studed fin tube is made by electrical resistance welding specially formed studs(round pins ) in rows around the tube. The Studs can be supplied in a variety of sizes and shapes. Stud tube has a very high heat transfer efficiency. The heat exchange efficiency is equivalent to 2-3 times that of the bare pipe.
Finned tubes are used in applications where efficient cooling is required to generate electricity or extract raw materials. Finned tubes are used in condensers, coolers and furnaces. The greater the surface area of finned tubes, the fewer tubes are required compared to using normal tubes. The higher the efficiency of finned tubes, the greater the space and cost savings can be.
Features of a Studded Fin Tube:
-It occupies less space and is, therefore, compact
-Highly durable
-Preferred over Finned tubes as they act as heat transfer systems
-Enhanced performance
