ASTM A376 TP347H High-Frequency Welded Finned Tubes for HRSG

ASTM A376 TP347H High-Frequency Welded Finned Tubes are designed for high-temperature heat recovery applications in Heat Recovery Steam Generators (HRSG). Manufactured with TP347H austenitic stainless steel base tubes and high-frequency resistance welded fins, these tubes provide an enlarged heat transfer surface, reliable fin attachment, and excellent performance under elevated temperature conditions.

TP347H is a niobium-stabilized stainless steel grade known for its high-temperature strength, creep resistance, and oxidation resistance. These properties make it suitable for demanding HRSG applications, particularly in superheater and reheater sections. The welded fin structure enhances heat exchange efficiency, helping recover more energy from exhaust gases while maintaining a compact equipment design.

Tube dimensions, fin height, fin thickness, fin pitch, and overall length can be customized according to project requirements and technical drawings.

The following parameters can be customized according to project drawings:

• Base tube outside diameter and wall thickness.

• Fin height and fin thickness.

• Fin pitch and fin density.

• Overall tube length and finned length.

• Fin material and surface treatment.

• Marking and packaging requirements.

TP347H is a niobium-stabilized austenitic stainless steel designed for high-temperature applications. Its chemical composition provides good resistance to high-temperature oxidation and supports improved creep strength.
