Product Description

Reinforced Flexible Graphite Gasket Material

Products Description
 

Material Composition & Production
Reinforced flexible graphite gasket material is manufactured through a multi-stage process: Natural graphite flakes undergo chemical intercalation and thermal expansion (1000-1200°C), generating expanded graphite with a bulk density of 3.2 kg/m³. This base material is then mechanically reinforced with stainless steel mesh (304/316L) or perforated alloy foils through high-pressure lamination, creating a hybrid structure that combines graphite's inherent properties with metallic reinforcement.

Structural Advantages

  • Enhanced Tensile Strength: 15-25 MPa vs. 5-8 MPa for non-reinforced grades

  • Directional Compression Stability: ≤5% thickness variation under 50 MPa cyclic loading

  • Pressure Adaptability: Effective sealing from vacuum (10⁻³ Pa) to 40 MPa systems

  • Thermal Bridging: Reduced heat transfer across sealed interfaces (Thermal conductivity: 5-20 W/m·K adjustable)

Operational Performance

  • Temperature Range: -240°C (cryogenic) to +850°C (oxidizing environments)

  • Chemical Compatibility: Resists 98% concentrated H₂SO₄, 50% NaOH, and hydrocarbon fluids

  • Creep Resistance: <0.2% permanent deformation after 2000h at 300°C/25 MPa

Industrial Applications

  1. High-Pressure Energy Systems:

    • Oil & gas wellhead sealing (API 6A/ISO 10423 compliant)

    • Hydrogen compressor valve stack gaskets

  2. Heavy Industrial Machinery:

    • Turbine flange seals for power generation

    • Hydraulic press platen insulation

  3. Transportation Engineering:

    • Fuel cell bipolar plate sealing in hydrogen vehicles

    • High-speed train brake system thermal barriers

  4. Process Industry:

    • Reactor manway seals in petrochemical plants

    • Pharmaceutical autoclave door gaskets (FDA 21 CFR 177.2600)
