Highly Durable ASTM A312 TP316L Stainless Steel Studded Fin Tube
What is studded fin 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.
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

Applications:
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.
