ASTM A335 P11 P22 P9 P91 CARBON STEEL FINNED TUBE FOR HEATER EXCANGER USE
HFW Solid Finned Tubes short for High Frequency Welded Helical Spiral Solid Finned Tube
Helical Finned Tubes provide the designer with high thermal efficiency and compact design solutions for a whole range of heat exchangers where clean flue gases are used. Helical finned Tubes are manufactured in both Solid and Serrated type.
Helical Solid Finned Tubes are manufacturer by helically wrapping continuous fin strip on tube. HF Resistance Welding Usually Employs Frequency Of 400 kHz. The fin wound around the tube And Continuous weld. The fin strip is wounded spirally onto the tube and welded continuously with a high frequency electrical process to the base tube along the spiral root. The fin strip held under tension and confined laterally as it is formed around the tube, thereby ensuring that the strip is in forceful contact with the base tube surface. A continuous weld is applied at the point where the fin strip first begins to bend around the tube diameter, using the gas metal arc welding process.
For a given tube or pipe size, the desired heat transfer surface area per unit length of tube can be obtained by specifying the appropriate fin height, fin thickness and /or number of fins per meter of length.
HFW Solid Finned Tube
This welded steel finned tube configuration can be used for any practically heat exchanger application, and is particularly suited to high temperature and high pressure applications. The important features of this configuration are efficient, effective bond of fin to tube under all conditions of temperature and pressure, and ability to withstand high fin-side temperatures.
A continuous helical fin is attached to the base tube by high frequency electric resistance welding in order to give an efficient and thermally reliable bond.
