Supplier's note

  1. Technical Breakthroughs:

    • ST52 Alloy Steel: Delivers 20% higher fatigue resistance than traditional carbon steel, ideal for dynamic machinery.
    • IEC62321 Compliance: Ensures zero hazardous substances, critical for food-grade and medical equipment.
    • Precision Hollow Sections: Oval and triangular shapes reduce material waste by 15% compared to standard pipes.
  2. Version Selection Guide:

    • Base Model: Suitable for standard structural or low-pressure fluid systems (e.g., HVAC ducts).
    • Advanced Model: Optimal for oil/gas pipelines requiring resistance to high pressures and temperatures.
    • Pro Model: Designed for extreme scenarios like offshore drilling or aerospace, where corrosion resistance and thermal stability are paramount.

With the Pro Model’s Duplex alloy, you can handle corrosive chemicals at 600°C—tripling industry benchmarks. Pair this with its seamless oval profile to ensure minimal turbulence in high-viscosity fluid transport.
