Product Name : Embedded G Type Fin Tube
Certification : ABS, BV, DNV, CCS, LR
Base Tube Material: ASTM A179
Type: Seamless cold-drawn low-carbon steel tubes.
Excellent thermal conductivity (good for heat transfer).
Good corrosion resistance in boiler feedwater and steam condensate environments.
Smooth internal bore (minimizes pressure drop and fouling).
High pressure and temperature capability.
Relatively cost-effective compared to alloy steels.
Typical Applications: Ideal for tubesheets in shell-and-tube heat exchangers handling water, steam, and condensate.
Fin Type: Embedded (G-Fin)
Manufacturing Process: A strip of fin material (usually carbon steel or sometimes stainless steel for corrosion resistance) is fed into a precision machine. The machine uses hardened steel wheels or tools to simultaneously cut a helical groove into the base tube wall and physically deform the fin strip into this groove under high pressure. The fin base becomes mechanically locked ("embedded") into the groove.

In Summary:
An A179 Embedded G-Type Fin Tube combines a seamless low-carbon steel base tube (ASTM A179), chosen for its thermal conductivity, pressure capability, and water/steam corrosion resistance, with high-performance helical fins mechanically locked into grooves machined into the tube wall. The "Embedded G" process creates an exceptionally strong bond, resulting in highly efficient and durable heat transfer, making it a premium choice for demanding applications like heat recovery boilers and economizers. The "G-Type" refers to the specific profile and method of the embedded fin groove.
