    ASME SA335 P9 Chromium-Molybdenum Alloy Studded Finned Tubes for High-Temperature Furnace Applications


    High-Frequency Welded ASME SA335 P9 Studded Finned Tubes | Durable Chromium-Molybdenum Alloy for Extreme Heat Furnace Systems


    Product Overview


    Yuhong Holding Group Co., Ltd. introduces ​ASME SA335 P9 Studded Finned Tubes, engineered for high-temperature industrial applications. Utilizing high-frequency welding (HFW) technology, these tubes combine chromium-molybdenum alloy durability with optimized heat transfer efficiency.


    Key Features


    1. Material & Chemical Composition
    • Base Material: ASME SA335 P9 Chromium-Molybdenum Alloy Steel.
    • Fin Material: High-grade stainless steel (AISI 304/316L) for corrosion resistance.
    • Chemical Composition:
    ElementCrMoCMnSi
    Composition8.0-10.0%0.90-1.10%≤0.15%0.30-0.60%0.50-1.0%

    Compliant with ASME and ASTM standards.


    2. Mechanical Properties
    PropertyValue
    Tensile Strength≥620 MPa
    Yield Strength≥415 MPa
    Elongation (A50)≥20%
    Operating Temperature-20°C to 650°C
    3. Manufacturing Process
    • High-Frequency Welding (HFW): Ensures 95% weld integrity between studs and base tube.
    • Studded Fin Design: Spiral studs (diameter: 8-12mm) increase surface area by 3-5x.
    • Post-Weld Treatment: Shot blasting and anti-corrosion coating (zinc or epoxy).
    4. Applications
    • High-Temperature Furnaces: Cement kilns, steel reheating furnaces.
    • Heat Recovery Systems: Boilers, economizers.
    • Oil & Gas: Crackers, reformers.

    Advantages

    1. Enhanced Heat Transfer: 30-50% higher efficiency compared to smooth tubes.
    2. Corrosion Resistance: Suitable for acidic or sulfur-rich environments.
    3. Customization: Available in lengths up to 18m and stud configurations (helical/axial).

    FAQ
