Product Description

Alloy Steel Seamless Tube ASTM A376 TP347H, Solid Fin Tube, For Convection Coil Tube

Product Introduction

The ASTM A376 TP347H Solid Fin Tube is made from high-temperature austenitic stainless steel (347H), designed for high-performance heat transfer in convection sections of furnaces and boilers. The solid fin is welded directly onto the tube surface using High Frequency Welding (HFW) or manual processes, creating a durable structure capable of operating under extreme thermal and corrosive conditions.

Chemical Composition – ASTM A376 TP347H

Element	Content (%)
C	0.04 – 0.10
Mn	≤ 2.00
P	≤ 0.045
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	≤ 217 HBW
Max. Service Temp	~ 1000°C (1830°F)

Advantages

Excellent High-Temperature Strength
Ideal for use in superheater and reheater tubes in power plants.
Enhanced Creep Resistance
Nb-stabilization makes 347H superior under prolonged high-heat exposure.
Superior Corrosion & Oxidation Resistance
Maintains integrity in flue gas environments with high sulfur content.
Solid Fin Structure
Provides mechanical durability, long service life, and efficient heat transfer.
Weldable and Formable
Supports complex U-bends and coil configurations for compact convection sections.

Applications

Mainly used in high-temperature heat recovery and energy conversion systems, such as:

Furnace Convection Coils
Power Plant Boilers
Petrochemical Reheaters
Waste Heat Recovery Units
Refinery Heater Tubes
