ASME SA335 P11 Alloy Steel HFW Serrated Fin Tube with Gr.11 Fin Material for Heater Coil

Key Features:

1. Base Tube Material: ASME SA335 P11 Alloy Steel, a high-strength, heat-resistant alloy steel designed for use in high-temperature and high-pressure applications such as heater coils. It is highly resistant to oxidation and corrosion, making it suitable for harsh environments.
2. Fin Material: Gr.11 Steel, typically a variant of the chrome-moly alloy, provides additional heat resistance and strength, making it an excellent choice for fins that need to withstand elevated temperatures.
3. Fin Type: Serrated Fin, designed to increase the heat transfer surface area and improve thermal efficiency by causing turbulence in the surrounding fluid. The serration design enhances performance by disrupting the boundary layer of fluid, allowing for better heat dissipation.
4. Application: Primarily used in heater coils for efficient heat transfer in various industrial heating applications such as power plants, chemical processing, and heat exchangers.
