Base Tube Material: ASME SA192 Carbon Steel, a high-strength, seamless carbon steel tube designed for high-pressure and high-temperature applications, specifically for use in fired heater systems. Known for its good mechanical properties, it is highly suitable for heat exchangers and boiler systems.
Fin Material: Carbon Steel (CS) Fin Strip, offering strength and durability, while also providing an excellent surface for heat transfer. The serrated fin design enhances the heat transfer capability by disrupting the airflow around the tube.
Fin Type: Serrated Fin, designed to improve heat transfer by creating turbulence in the fluid surrounding the tube. The serrated edges increase surface area and reduce boundary layers, thereby enhancing heat exchange efficiency.
Application: Primarily used in fired heaters, where efficient heat transfer is essential for effective thermal performance. These fin tubes are designed to perform under high temperatures and pressures typically found in industrial heating applications.

Enhanced Heat Transfer: The serrated fin design increases the heat transfer surface area and induces turbulence in the surrounding fluid, leading to higher thermal efficiency.
High-Temperature Resistance: Both ASME SA192 Carbon Steel and Carbon Steel Fin Strips are capable of withstanding high-temperature environments, making this fin tube perfect for fired heater applications.
Corrosion Resistance: While carbon steel provides good mechanical properties, the serrated fin strip offers an efficient surface for heat transfer, with sufficient corrosion resistance in typical fired heater applications.
Cost-Effective: The combination of carbon steel and the serrated fin design ensures a cost-effective solution that maximizes heat transfer without the need for more expensive alloys.
Durability and Strength: Designed for use in demanding environments, the fin tube can handle both high pressures and temperatures typically encountered in fired heaters.

Fired Heaters: Primarily used in fired heater applications in industries such as oil and gas refining, petrochemical plants, and power generation.
Heat Exchangers: Suitable for use in heat exchangers where high-temperature heat transfer is critical.
Boilers: Used in boiler systems, particularly in the heating sections, where efficient heat transfer is needed for steam generation.
Industrial Heating Systems: Ideal for applications where heat transfer efficiency is critical, and high temperatures are sustained.
