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.
