Stainless steel HF welded finned solid tubes are specifically designed for waste heat recovery from industrial furnace flue gas, heat exchange in convection sections, and auxiliary heating of process furnaces.

 

Core Advantages of Stainless Steel HF Welded Finned Solid Tubes in Furnace Service

 

ASTM A312 TP304 base tubes are resistant to high-temperature oxidation and suitable for continuous operation in furnaces with flue gas temperatures of 250–400°C.

 

High-frequency welded fins provide a strong metallurgical bond, preventing fin loosening under furnace vibration and thermal expansion.

 

Anti-scaling and easy-to-clean, the smooth stainless steel surface reduces dust/ash adhesion to the furnace tail heating surface.

 

Corrosion resistance: Prevents pitting and rust caused by low-temperature condensation in the furnace.

Using these in mining cooling equipment under pretty rough conditions. They’ve been running for a month now and are super stable.

It's genuine 321H — titanium-stabilized, so no worries about sensitization or intergranular corrosion during welding. Our welder said it welded nicely with no cracking.

Cost and reliability are key for Indian refineries. We installed these fin tubes in Mumbai’s cooling towers, achieving 16% energy savings versus local suppliers. ASTM A213 T11 compliance ensured no failures during monsoon humidity (90%+ RH), and the low price saved $8K upfront.
