TP347 Studed Fin Tube High Frequency Welding Type 11Cr Pin for Fired Heater
Studed Finned Tube is manufactured by wrapping a continuous fin strip in a spiral on the tube. HF resistance welding typically uses a frequency of 400 kHz. The fin is wrapped around the tube and continuously welded. The fin strip is wound spirally on the tube and continuously welded with high frequency electrical process to the base tube along the spiral root. The fin strip is held under tension and confined horizontally as it is moulded around the tube, thus ensuring that the strip is in strong contact with the surface of the base tube. Continuous welding is applied at the point where the fin strip begins to bend around the tube diameter using the gas metal arc welding process.
For a given tube or tube size, the required heat transfer surface area per unit length of tube can be obtained by determining the appropriate fin height, fin thickness and/or number of fins per metre of length.

Features of Studed tubes
Seamless steel tubes are mainly used in boilers and furnaces. Mostly used in corrosive environments. In the petrochemical industry, the denser crude oil passes through the spiked tube. Heat is generated from the outside of the tube. At the other end of the tube, we get the liquid product, which is subsequently sent for processing.
Studded tubes are also used in water tube boilers. They help to heat water. Studded tubes are oval in shape and are welded to the boiler.
The use of threaded pipes reduces the use of bare pipes as the heat transfer surface of one threaded pipe can replace the heat transfer surface of 4 to 10 bare pipes.
Threaded tubes can be used where harsh fuels are used that can cause damage to the environment. To prevent corrosion, the outer surface of the studded pipe can be coated or treated with a protective layer.
Riveted tubes are also used in soda ash boilers and fluidised bed reactors as they minimise erosion.
They are also used in steel mills, air coolers, power plants, heat exchangers, etc.
