High Frequency Welded (HFW) studded fin tubes designed for superior heat transfer efficiency in demanding industrial applications.
Product Overview
ASTM A335 P9 P11 carbon steel HFW studded fin tubes for heat exchangers with black painted finish. These high-frequency welded spiral fin tubes provide exceptional thermal efficiency and compact design solutions for various heat exchangers utilizing clean flue gases.
Manufacturing Excellence
Yuhong Group has been a leading supplier of stainless steel, duplex, and nickel seamless pipes for over 10 years. With annual sales exceeding 80,000 tons, we serve customers in more than 45 countries across mining, power generation, petrochemical, chemical, food, paper, gas, and liquid industries.
HFW Solid Fin Tube Technology
HFW solid fin tubes are manufactured by spirally winding continuous fin strips around the base tube and continuously welding using high-frequency contact welding at 400 kHz. This ensures strong contact between the fin strip and the base tube surface, with welding occurring at the root of the spiral where the fin strip bends around the tube diameter.
Key Product Features
Material: ASTM A335 P9 alloy steel known for excellent mechanical properties, corrosion resistance, and high-temperature performance
High Frequency Welding: Superior weld strength, integrity, and consistency with seamless bonding between fins and base tube
Studded Tube Design: Enhanced heat transfer efficiency through increased surface area and improved thermal conductivity
Technical Specifications
Base Tube: Diameter 20mm to 219mm, thickness 2mm to 16mm. Materials include carbon steel, stainless steel, alloy steel, weather-resistant steel, duplex steel, super duplex steel, Inconel, high nickel-chromium alloys, CK 20, and others.
Fin Details: Fin thickness 0.8mm to 4mm, fin height 0.25" (6.35mm) to 1.5" (38mm), fin density 43 fins per meter to 287 fins per meter. Materials include carbon steel, stainless steel, alloy steel, weather-resistant steel, duplex steel, and Incoloy.
