Product Description

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

Element	Content (%)
C	0.04 – 0.10
Mn	≤ 2.00
P	≤ 0.040
S	≤ 0.030
Si	≤ 1.00
Cr	17.0 – 19.0
Ni	9.0 – 13.0
Nb (Cb)	10 × C min
Fe	Balance

Mechanical Properties – TP347H

Property	Value
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.
