ASTM A106 Gr.B Tube With Cu-T2 Fin with Embedded Fin Tube G-Type
Inlay fin tubes, also known as G-fin tubes, are manufactured by mechanically wrapping fin material around a base tube. Their key feature is that the fin legs are embedded into the base tube surface under tension, forming a tight mechanical and metallurgical bond without the need for any filler material.
The combination of a sturdy carbon steel base tube and highly thermally conductive copper fins provides a unique balance of strength, corrosion resistance, and excellent heat transfer performance.

Key Features:
High-Pressure/High-Temperature Resistance: Designed for
high-pressure systems, they can withstand temperatures typical of
boiler, superheater, and heat exchanger applications.
Strength and Durability: The seamless construction provides
exceptional mechanical strength and integrity.
Weldability: They can be easily welded to carbon steel piping,
headers, and tubesheets.
Fin Material: Copper UNS C11000 (Cu-T2)
Standard: UNS C11000 (also known as C110 or electrolytic tough
pitch copper - ETP copper) is a standard commercial copper.
Applications:
This specialized tubing is ideal for applications where high
thermal performance and mechanical durability are critical:
Heat Recovery Steam Generators (HRSGs): Used in the economizer and
low-pressure section.
Air-Cooled Steam Condensers: Used in power plants and large
industrial processes.
Finned Tube Boilers: Used for increased efficiency and compact
size.
Oil and Air Coolers: Used in industrial processes where air is used
to cool process fluids.
HVAC & Refrigeration Systems: Used in large industrial heating
coils or specialized heat recovery units.
