Product Specifications
Product Name: HFW Serreted Finned Tube
Bare Tube Specification & Material: ASTM A312 TP347

Fin Thick: 0.3~3mm
Applications: Power Plants, Chemical Plants, Oil Refineries
Product Overview

ASTM A312 TP347 Serrated Spiral High-Frequency Welding (HFW) Finned Tube is an advanced heat transfer solution designed for extreme oxidation and creep resistance. This high-performance component combines a seamless stabilized austenitic stainless steel base tube (ASTM A312 TP347) with helically wound serrated spiral fins bonded via high-frequency resistance welding.

Key Advantages: Serrated fin edges disrupt boundary layers, enhancing heat transfer by 35% compared to smooth fins, while the Nb-stabilized alloy provides exceptional resistance to intergranular corrosion at temperatures up to 870°C (1,598°F). Ideal for high-ash flue gases and cyclic thermal shock applications.
Material 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
  • 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
Engineering Benefits
  • 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 Options: Fin height (12-25mm), serration depth (1-3mm), FPI (3-8)
