ASTM A376 TP347H Pipe With CS Fins HFW Fin Tube, Professional-Grade Heat Resistant Solution
Base pipe: Manufactured from ASTM A376 TP347H grade austenitic stainless steel seamless pipe. This material is stabilized with niobium, specifically designed for high-temperature and high-pressure service. It offers exceptional creep resistance, stress rupture strength, and resistance to steam-side oxidation.
Fins: Made from Carbon Steel strip, which acts as an extended heat transfer surface.
Manufacturing Process: The carbon steel fins are securely welded onto the external surface of the TP347H base pipe via High-Frequency Welding technology. This process creates a metallurgical bond between the fins and the base pipe, ensuring minimal contact thermal resistance and superior heat transfer efficiency.
It is an energy-saving heat transfer component fabricated by integrally bonding carbon steel fins to a TP347H stainless steel base pipe through the HFW process. This design combines the intrinsic superior properties of TP347H under high temperature and pressure with the cost-effectiveness and efficient heat transfer of carbon steel fins. Its primary applications include superheaters, reheaters, and heat exchanger components in extreme environments such as utility boilers and heat recovery systems.

2. Key Features
Exceptional High-Temperature Strength: The TP347H base pipe, stabilized with Niobium, offers significantly improved creep resistance and stress-to-rupture strength. It can operate reliably at service temperatures up to 760°C, making it an ideal choice for superheaters and reheaters.
Optimized Heat Transfer Efficiency: The carbon steel fins are metallurgically bonded to the base pipe via the High-Frequency Welding process, resulting in minimal contact thermal resistance. This significantly increases the heat transfer area, maximizing overall efficiency and reducing energy consumption.
Superior Corrosion & Oxidation Resistance: The TP347H material offers excellent resistance to oxidation and flue gas corrosion. It is particularly resistant to "steam-side oxidation" and sensitization, ensuring a long service life even in harsh operating conditions.
Robust and Reliable Connection: The HFW technology ensures a continuous, high-strength bond with nearly 100% contact between the fin and the pipe. This connection boasts high tensile strength, capable of withstanding thermal expansion and contraction stresses, preventing loosening and failure.
Cost-Effective Solution: The composite design of a TP347H base pipe and CS fins ensures corrosion resistance at critical points while utilizing more cost-effective carbon steel as the extended heat transfer surface, offering our customers the best value.
3. Key Applications
Utility Boilers: Primarily for high-temperature superheaters and reheaters.
Heat Recovery Steam Generators: Recovering energy from high-temperature exhaust gases, e.g., from gas turbines.
Chemical & Petrochemical Plants: Used in high-temperature process heaters like cracking furnaces and reformer furnaces.
