    ASME SA335 P9 Alloy Steel High Frequency Welding Helical Solid Fin Pipe For Furnace

    High-Frequency Welded ASME SA335 P9 Helical Finned Tubes | Extreme Heat-Resistant Alloy Steel for Industrial Furnace Systems


    Product Overview


    Introducing ​ASME SA335 P9 High-Frequency Welded Helical Finned Tubes, designed for extreme-temperature industrial furnace applications. These tubes combine ​chromium-molybdenum alloy durability with ​high-efficiency heat transfer, making them ideal for harsh environments.



    Key Features


    1. Material & Chemical Composition
    • Base Tube: ASME SA335 P9 Chromium-Molybdenum Alloy Steel (Cr: 8.5-9.5%, Mo: 0.90-1.10%)
    • Fin Material: High-grade stainless steel (AISI 304/316L) for corrosion resistance.
    • Chemical Composition:
    ElementCrMoCMnSi
    Composition8.5-9.5%0.90-1.10%≤0.15%0.30-0.60%0.50-1.0%

    Compliant with ASME SA335 and ASTM A213 standards.


    2. Mechanical Properties
    PropertyValue
    Tensile Strength≥620 MPa
    Yield Strength≥440 MPa
    Elongation (A50)≥20%
    Operating Temperature-20°C to 650°C
    3. Manufacturing Process
    • High-Frequency Welding (HFW): Achieves ​95% weld integrity between fins and base tube through automated spiral winding.
    • Post-Weld Treatment: Shot blasting + anti-corrosion coating (zinc or epoxy) for enhanced durability.
    • Quality Control: 100% hydrostatic testing (1.5x design pressure) and ultrasonic inspection.
    4. Applications
    • High-Temperature Furnaces: Cement kilns, steel reheating systems.
    • Heat Recovery Units: Boilers, economizers, and air preheaters.
    • Oil & Gas: Crackers, reformers, and sulfur recovery units.

    Advantages

    1. Superior Heat Transfer: 4-7x higher efficiency than smooth tubes due to spiral fin design.
    2. Corrosion Resistance: Withstands acidic/sulfur-rich environments (pH 2-12).
    3. Long Service Life: 2-3x lifespan over conventional welded tubes.

    FAQ


    Q1: What is the lead time for bulk orders?
    A: Standard lead time is ​4-6 weeks for 20-ft container loads.


    Q2: Can these tubes withstand thermal cycling?
    A: Yes, the ASME SA335 P9 alloy ensures stability under repeated heating/cooling.


    Q3: Are certifications available?
    A: We provide ​ASME, ISO 9001, and EN 10204-3.1 certifications.
