Manufacturer Profile
As a leading Chinese manufacturer of fin tubes, we have extensive project experience in heat exchanger and boiler systems, marine applications, and oil & gas projects. Our products are exported to over 80 countries worldwide, supported by advanced production equipment and skilled technical staff.
Product Overview
Helical solid fin tubes, also known as high frequency welding fin tubes, are manufactured using a specialized process that utilizes high-frequency electrical currents to fuse metal edges without additional filler materials.
Material Specifications
ASTM A213 TP347H S34709 base tubes are seamless ferritic and austenitic steel tubes designed for boiler, superheater, and heat-exchanger applications. Grades containing "H" provide enhanced creep-rupture strength.
Manufacturing Process
Tubes are manufactured through the seamless process and can be hot finished or cold finished. Grade TP347HFG is specifically cold finished with heat treatment at 2000°F (1100°C) for cold worked or 1925°F (1050°C) for hot rolled.

Helical solid fin tubes manufacturing process
AL5052 Fin Material
AL5052 is an aluminum-magnesium alloy with exceptional corrosion resistance against seawater and salt spray, making it ideal for marine applications such as liquefied natural gas tankers. While not heat treatable, it can be hardened through cold working.
Product Advantages
  • Increased heat exchange area reduces heat transfer and metal flow
  • Excellent corrosion resistance, wear resistance, and thermal stability
  • Low contact thermal resistance with anti-ash capability
  • Reduces required installation space while maintaining high reliability
  • Enhanced stiffness and seismic performance
Applications
Ideal for power stations and high-temperature equipment in the oil industry, including:
  • Boilers and Steam Generators
  • Heat Exchangers and Furnaces
  • Economizers and Combustion Heaters
  • Large Air Coolers
  • Drier Heaters
