Solid Fin Tube HFW ASTM A213 TP347H For Boiler

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.

ASTM A213 TP347H (UNS S34709) are seamless austenitic steel tubes designed for applications in boilers, superheaters, and heat exchangers. Grades designated with 'H' provide superior creep-rupture strength at elevated temperatures.

• 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

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

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.
