Product Description

What is ASTM A312 TP347 Serrated Spiral HFW Finned Tube?

ASTM A312 TP347 Serrated Spiral High-Frequency Welding (HFW) Finned Tube is an advanced heat transfer solution for extreme oxidation and creep resistance. It combines a seamless stabilized austenitic stainless steel base tube (ASTM A312 TP347) with helically wound serrated spiral fins bonded via high-frequency resistance welding. The serrated fin edges disrupt boundary layers, enhancing heat transfer by 35% vs. smooth fins, while the Nb-stabilized alloy resists intergranular corrosion up to 870°C (1,598°F). Ideal for high-ash flue gases and cyclic thermal shock services.

Chemical & Mechanical Properties

Chemical Composition (Per ASTM A312/A999)

Element	TP347 Base (%)	Critical Function
Chromium (Cr)	17.0-20.0	Oxidation shield
Nickel (Ni)	9.0-13.0	Austenite stability
Niobium (Nb)	10×C min*	Intergranular corrosion resistance
Carbon (C)	≤ 0.08	Weldability
Manganese (Mn)	≤ 2.00	Strength
Silicon (Si)	≤ 1.00	Deoxidation
Phosphorus (P)	≤ 0.045	Purity
Sulfur (S)	≤ 0.030	Machinability

Mechanical Properties (Post-Weld Annealed)

Property	Value
Tensile Strength	≥ 515 MPa
Yield Strength	≥ 205 MPa
Max Service Temp.	870°C (1,598°F)
Hardness	≤ 192 HB
Fin Bond Shear Strength	> 140 MPa
Oxidation Resistance	≤ 0.1 g/m²*h (980°C/air)

Key Applications & Competitive Advantages

Waste-to-Energy Boilers: Superheaters in municipal waste incinerators (resists KCl/ZnCl₂ corrosion)
Refinery Heaters: Convection sections for vacuum residue upgrading
Chemical Processing: Cracked gas heat exchangers in ethylene plants
Power Generation: SCR duct heaters for coal-fired units (handles fly ash erosion)
Cement Plants: Preheater exhaust gas economizers

Why Engineers Specify TP347 Serrated HFW Tubes

Zero Carbide Precipitation: Nb stabilization prevents sensitization in 425-870°C range

Ash Self-Cleaning: Serrated fins reduce fouling by 50% (per EPRI study)

Thermal Fatigue Resistance: 2x longer life than TP304H in cyclic duty

Customization: Fin height (12-25mm), serration depth (1-3mm), FPI (3-8)
