ASTM A312 TP347 High Frequency Welded Spiral Serrated Finned Tubes For Heat Exchangers
High Frequency Welded Serrated Fin Tubes is a spiral fin tube formed by welding the steel strip on the base tube surface with high frequency welding technique， And the fin strip is serrated before welding. The High Frequency Welded Serrated Fin Tube is one kind of tubular type of efficient heat transfer elements which has serrated fins. Our TONG CHUANG GROUP has more than 30 years’ manufacturing experience of fin tubes and our high-quality fin tubes have been exported to more than 60 countries.
