Oct 01, 2015 · It is found that the serrated welded spiral fin-and-tube heat exchanger gave a higher j-Colburn factor and f-friction factor than the L-footed spiral fin, crimped spiral fin, plain fin, and circular fin at high Reynolds number (400015,000). It is clearly seen that the serrated welded spiral finned tube heat exchanger will provide higher heat transfer enhancement than other fin types by operating at a high
China High Frequency Welded Spiral Fin Tubes The high frequency welded spiral finned tube is one kind of tubular type efficient heat transfer element having spiral fins. The extended surfaces (fins) could be either solid or serrated create several to dozens of times of the heat transfer area than bare tube.
The height of the fin affects the basic parameter of mass flow, which affects heat transfer and pressure drop; the manufacturing limit of the integral fin is much more limited than that of the serrated fin tube; the fin efficiency decreases, and the overall wing The film is more severely degraded than the serrated fins; for fins with a fin
EXTENDED SURFACE TUBES - Your Partner for pipe and The fin strip is wound spirally onto the tube and welded con- tinuously to the tube along the spiral root. Advantages:Strong connection between fin and base tube, prevents loosening of fins because of heat stress, oxidization, corrosion etc., use at very high temperatures possible. (see details on page 18)

HFW Serrated Finned Tubes is short for High Frequency Welded Helical Spiral Serrated Finned Tubes. Helical serrated finned tubse, serrated fins cut from metal strip and then helically wound around the tubes.
Heat Exchanger Fin Tube ASTM A312 TP304 SUS 304 1.4301 High quality Heat Exchanger Fin Tube ASTM A312 TP304 SUS 304 1.4301 OD 1/4''~8'' Stainless steel smls Fin tube from China, China's leading finned copper tube product, with strict quality control heat exchanger fin tube factories, producing high quality heat exchanger fin tube products.
High Frequency Welded Serrated Finned tube - China The fin strip is wounded spirally onto the tube and welded continuously with a High Frequency Electrical process to the tube along the spiral root. As the fin strip is formed around the tube its outer (serrated) edge spreads, opening the segments like petals of a daisy.
HFW Solid Finned Tube, High Frequency Welded Solid Finned Pipe. Helical finned Tubes are manufactured in both Solid finned Tube and Serrated Finned Tube. Helical Finned Tubes provide the designer with high thermal efficiency and compact design solutions for a whole range of heat exchangers.
High Frequency Welded Spiral/Helical Fin Tube & Tubos Helical finned Tubes are manufactured in both Solid and Serrated win profiles. Helical Solid Finned Tubes are produced by helically wrapping continuous fin strip tube. The fin strip is wounded spirally onto the tube and welded continuously with a High Frequency Electrical process to the tube along the spiral
How to Produce the HF Welded Serrated Fin Tube - May 06, 2018 · Serrated fin tube is now more and more popular in the manufacturing of boiler, pressure vessel and other heat exchanger equipments. It has more advantages than other common solid fin tube, which mainly includes:Higher heat transfer coefficient.
