ASTM A312 TP347 HFW Serrated Fin Tubes

ASTM A312 TP347 HFW Serrated Fin Tubes HFW Serrated Fin Tubes means High Frequency Welded Helical Spiral Serrated Fin Tubes. HFW serrated fin tubes serrated fins cut from metal strip and then helically wound around the base tubes. This serrated fin has better heat transfer properties compared to solid fins.The serrated fin tubes have better heat transfer effect than solid fin tubes. And the serrated fins also improve the function of preventing ash deposition.The High Frequency Welded Spiral Serrated FinTube is one of the most widely used HFW spiral fin tubes, and is usually used in power plants, waste treatment systems and petrochemical industries and so on. Features: Fast welding speed Strong self-cooling effect of weldments Resistance to oxidation Good microstructure and properties of the weld Corrosion resistance Abrasion resistance Low contact thermal resistance High stability Anti ash…
