    Products Description

    Advanced High - Temperature Graphite Gasket Solutions for Boiler Systems

    Product Engineering

    Engineered using natural graphite flakes via a proprietary chemical intercalation and thermal expansion process, high - temperature graphite gasket materials (including flexible sheets, foil, paper, tape, and strips) are transformed into exfoliated worm - like structures with a bulk density of 0.003g/cc. These structures are compression - formed into binder - free rolls or sheets, achieving purity levels exceeding 99.8%. The resulting materials exhibit unique properties critical for boiler applications.

    Boiler - Specific Performance Features

    1. Extreme Thermal Stability
      • Maintains structural integrity from cryogenic (-200°C) to superheated steam (+650°C) conditions in boiler drums and pipelines.
      • Low thermal expansion coefficient (≤3ppm/°C) prevents gasket embrittlement during thermal cycling.
    2. Pressure & Corrosion Resistance
      • Withstands operating pressures up to 100 bar in high - pressure boilers while maintaining 95% compression recovery.
      • Resists chemical attack from boiler water treatment chemicals (amines, phosphates) and acidic flue gases.
    3. Mechanical Durability
      • Compressive strength of 55 MPa resists deformation in boiler flange connections.
      • Self - lubricating properties reduce friction in moving parts like safety valve stems.

    Applications in Boiler Systems

    1. Steam Header Seals
      • Custom - cut gaskets for ASME B31.1 boiler piping, ensuring leak - free operation in high - velocity steam paths.
      • Composite designs with stainless steel reinforcement for critical superheater sections.
    2. Burner Gaskets
      • Directly integrated into combustion chambers to seal against extreme temperatures and pressure differentials.
      • Graphite - ceramic hybrid versions available for biomass - fired boilers.
    3. Manhole & Handhole Seals
      • Thick - cut sheets (3 - 5mm) provide reliable seals for boiler access points, compliant with ASME BPVC Section I.

    Custom Specifications for Boilers

    • Sizes:
      • Rolls: 1000mm/1500mm width, 30m/50m/80m length.
      • Sheets: 1000mm x 1500mm, thicknesses from 0.15mm (valve seats) to 5mm (flange gaskets).
    • Density: 0.8–1.25 g/cm³ (adjustable to balance softness for dynamic seals vs rigidity for static joints).
    • Special Features:
      • Laser - engraved channels for optimized heat dissipation in boiler tube seals.
      • PTFE - impregnated variants for enhanced resistance to condensate corrosion.

    Compliance & Testing

    • Meets EN 12952 (water tube boilers) and ASME BPVC Section VIII standards.
    • Tested for creep relaxation (ASTM F38), thermal conductivity (ASTM C518), and flame spread (ASTM E84).
    • CE/PED certified for pressure equipment directive compliance.

    Why Choose Our Boiler Gaskets?

    • Proven Reliability: Over 10 years of service life in continuous operation, reducing maintenance costs by 50%.
    • Energy Efficiency: Low thermal conductivity improves boiler efficiency by 2 - 3%.
    • Technical Support: On - site gasket installation training and failure analysis provided.

    Engineered to deliver leak - tight performance in the most challenging boiler environments.
