Corrosion Resistance: Excellent against oxidation, sulfur, and acidic flue gases.
Mechanical Strength: Good creep & stress rupture resistance (superior to standard 304).

HF Welding Solid Fin Tubes ASTM A312 TP304H For Waste Heat Recovery Units

Waste Heat Recovery Units (WHRUs) capture and reuse thermal energy from industrial exhaust gases, improving energy efficiency and reducing emissions. HF-welded solid fin tubes made of ASTM A312 TP304H stainless steel play a critical role in these systems due to their high-temperature strength, corrosion resistance, and efficient heat transfer capabilities.

304H stainless steel maintains strength at high temperatures (up to 900°C), ensuring long-term performance.Solid fins provide a larger heat exchange surface area than bare tubes, increasing thermal efficiency.

Applications in WHRU Systems

Heat Recovery Steam Generators (HRSGs)

Economizers

Air Preheaters

Flue Gas Condensers

HF-welded solid fin tubes (ASTM A312 TP304H) are essential for efficient, durable WHRUs in industries such as:Power generation (HRSGs, economizers) / Petrochemical (fired heaters, reformers) / Cement, steel, and waste incineration (flue gas heat recovery).
