Descrizione di prodotto

ASTM A312 TP347H Stainless Steel Seamless Pipe, Serrated Fin Tube, For Furnace Tube


Product Overview

ASTM A312 TP347H is a high-temperature, stabilized austenitic stainless steel with added columbium (niobium) for improved creep strength. When made into Serrated Fin Tubes using High-Frequency Welding (HFW), this tube becomes ideal for furnace convection sections, offering enhanced heat transfer efficiency and extended service life under cyclic thermal stress and oxidizing conditions.


Chemical Composition – ASTM A312 TP347H

ElementContent (%)
C0.04 – 0.10
Mn≤ 2.00
P≤ 0.040
S≤ 0.030
Si≤ 1.00
Cr17.0 – 19.0
Ni9.0 – 13.0
Nb (Cb)10 × C min
FeBalance

Mechanical Properties – TP347H

PropertyValue
Tensile Strength≥ 515 MPa
Yield Strength≥ 205 MPa
Elongation≥ 35%
Hardness (HBW)≤ 192 HB
Max. Working Temp~ 1050°C (1922°F)

Advantages of TP347H Serrated Fin Tube

  • High Temperature Resistance
    Ideal for superheaters, heaters, and furnaces, TP347H withstands long-term service at elevated temperatures without creep deformation.

  • Improved Heat Transfer Efficiency
    The serrated fin design increases turbulence and surface area, boosting heat transfer while minimizing fouling.

  • Oxidation & Corrosion Resistance
    Excellent performance in oxidizing atmospheres, especially in fuel-fired furnaces.

  • Creep-Strength Enhanced
    Addition of niobium enhances structural stability under high stress and thermal cycling.

  • Weldability and Fabrication
    Good weldability with standard procedures; suitable for custom-designed fin configurations.


Application in Furnace Systems

The Serrated Fin Tube made of ASTM A312 TP347H is specifically used in:

  • Convection Section of Furnaces
    Absorbs radiant heat and transfers it efficiently to the working fluid (steam, oil, or gas).

  • Heater Banks & Superheaters
    Installed where both thermal efficiency and material durability are critical.

  • Refinery Fired Heaters
    In hydrocarbon processing, TP347H fin tubes are used in crude, reformer, and hydrotreater furnaces.
