Abbreviation for HFW solid finned tube high frequency welded helical spiral solid finned tube
Spiral finned tubes provide designers with high thermal efficiency and a compact design solution for a variety of heat exchangers using clean flue gas. There are two types of spiral finned tubes: solid type and serrated type.
Helical solid finned tubes are manufactured by helically wrapping a continuous strip of fins around the tube. High frequency resistance welding typically uses a frequency of 400 kHz. The fins are wrapped around the tube and welded continuously. The fin tape is helically wound on the tube and continuously welded to the base tube along the root of the helix by a high frequency electrical process. The finned band is held under tension and laterally restrained as it is formed around the tube, ensuring that the band is in strong contact with the surface of the base tube. Using a gas shielded metal arc welding process, a continuous weld is made at the point where the fin strip first begins to bend around the diameter of the tube.For a given tube or pipe size, the required 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 in any practical heat exchanger application, especially for high temperature and high pressure applications. Important features of this configuration are the efficient and effective bonding of the fin to the tube, and the ability to withstand high temperatures on the fin side under all temperature and pressure conditions.
The continuous helical fins are attached to the base tube by high frequency resistance welding to provide an efficient and thermally reliable bond.
