    Manufacturing & Design
    • Precision Forging: Ensures uniform wall thickness and tight radius tolerance (1.5D standard).
    • Solution Annealing: 925–1010°C heat treatment enhances grain structure for high-temperature stability.
    • HF Weld Compatibility: Matches finned tube systems with seamless integration in heater circuits.

    Applications
    Perfect for:
    • Industrial furnace radiant coils
    • Petrochemical reformer units
    • Waste heat recovery systems
    • Corrosive gas pipelines

    Key Advantages

    • Carbide Stability: Titanium addition prevents intergranular corrosion under cyclic heating.
    • Thermal Fatigue Resistance: Handles rapid temperature fluctuations common in furnace operations.
    • Dimensional Accuracy: Tight tolerances reduce flow turbulence and pressure drop.

    FAQ

    Q: Can these bends be used with acidic fuels?
    A: Yes, TP321H-S resists sulfuric and nitric acid corrosion typical in industrial exhaust.
    Q: What sizes are available?
    A: Standard sizes ½"–12", with custom dimensions for specific furnace layouts.
