Supplier's note

  1. Three Technical Breakthroughs:

    • Material Blend: The metal-graphite composite offers 40% higher tensile strength than traditional graphite gaskets.
    • Temperature Tolerance: The Pro Model’s 1000°C rating exceeds industry benchmarks by 20%, enabling use in ultra-high-temperature systems.
    • Flexibility: Unique bending properties reduce leakage points by 30% compared to rigid seals.

  2. Optimal Version Selection:

    • Base Model: Ideal for standard industrial boilers (e.g., power plants) operating below 600°C.
    • Advanced Model: Suitable for chemical processing plants needing 800°C resistance and medium-pressure (80 bar) systems.
    • Pro Model: Designed for extreme environments like aerospace or steel mills, where 1000°C and 120 bar performance are critical.

With the Pro Model’s 1000°C resistance, you can ensure reliable sealing in high-temperature boilers. Pair its flexibility with anti-corrosion coatings to create a maintenance-free solution for decades of operation.
