Nickel-Based ASME SB163 UNS N04400 Tubing is known for its resistance to high-temperature seawater and steam.
Finned tubes are used in applications where a hot fluid transfers heat through the tube wall to a cold fluid. The rate of this heat transfer depends on three factors: (1) the temperature difference between the two fluids, (2) the heat transfer coefficients between each fluid and the wall of the tube, and (3) the surface area contacted by each fluid. In the case of bare (unlined) pipe, when the outer surface area is not significantly greater than the inner surface area, the fluid with the lowest heat transfer coefficient will determine the overall heat transfer rate.

Processes of G-type Finned Tube
In G-fin tubes, the fins are made by embedding a metal strip into grooves. The grooves are formed in the base tube. The fins are placed over the grooves and then backfilled, thus holding the fins firmly in place on the base tube. Hence the name G-Fin Tube. The three processes described above are performed simultaneously. Because the fins are firmly attached to the base tube, the heat transfer of the G-Fin tube is expected to be maximized.
G-fin tubes are typically used in high temperature (approximately 400 degrees Celsius) environments. These fins are made of copper, carbon or aluminum and have relatively low resistance to atmospheric corrosion. On the other hand, their mechanical corrosion resistance is acceptable. Stainless steel and carbon steel fin materials can also be used, but special machining and tooling of the steel fin strips is required. Air coolers, radiators, etc. use g-shaped finned tubes.
