Overview:
ASME SB163 is a specification established by the American Society of Mechanical Engineers for seamless nickel and nickel alloy condenser and heat-exchanger tubes. The specification covers various grades of nickel and nickel alloys, including N04400, which is a grade of nickel-copper alloy.
Embedded G type fin tube is a type of heat exchanger tube that has fins embedded onto its surface. These fins are usually made of a different material than the tube and increase the surface area for heat transfer, thereby improving the efficiency of the heat exchanger.
When referring to ASME SB163 N04400 Embedded G type fin tube, it means a heat exchanger tube made of nickel-copper alloy with G type fins embedded onto its surface. This type of tube is commonly used in various industrial applications, including chemical processing, power generation, and oil and gas refining, where efficient heat transfer is essential.

Application:
SB163 N04400 is a nickel-based alloy that is commonly used in the manufacture of fin tubes. The embedded G type fin tube refers to a type of finned tube where the fins are embedded into the wall of the tube with a G-shaped profile.
The main application of SB163 N04400 embedded G type fin tubes is in heat exchangers. These tubes are used in various industries like chemical processing, power generation, petroleum refining, and HVAC systems.
The fins on the tubes increase the surface area of the tube, which enhances the transfer of heat between the fluid in the tube and the environment. The G-shaped profile of the fins ensures efficient heat transfer and provides a better balance between heat transfer and fluid pressure drop. The use of SB163 N04400 alloy in the fin tube also provides excellent resistance to corrosion and oxidation in high-temperature environments.
Overall, the use of SB163 N04400 embedded G type fin tubes can improve the performance and efficiency of heat exchangers, leading to energy savings and cost-effectiveness in various industrial applications.
