Product Description

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

ASTM A312 is a standard specification for seamless, welded, and heavily cold worked austenitic stainless steel pipes.

Chemical Composition (%)

Grade	C	Mn	P	S	Si	Cr
TP304H	0.04-0.10	2.00	0.045	0.030	1.00	18.00-20.00

Composition:
18-20% Chromium (Cr) – Provides oxidation resistance.
0.04-0.10% Carbon (C) – Improves creep resistance at high temps.

Mechanical Properties

Grade	Tensile Strength,min	Yield Strength (0.2%Offset,min)
Grade	75ksi (515 MPa)	30ksi (205 MPa)
TP304H	Elongation min. %	Heat Treating Temperature min.
TP304H	35%	1900°F [1040°C]

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 0

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).
