    Products Description

    ASTM-Certified Flexible Graphite Gasket Solutions

    Product Overview

    Engineered using advanced manufacturing processes, our flexible graphite materials—including sheets, foil, paper, tape, and strips—are derived from natural graphite flakes through a proprietary chemical intercalation process followed by thermal exfoliation at 1000°C+. This produces worm-like structures with an ultralow bulk density of 3 kg/m³, which are then compressed into binder-free rolls without fillers. The result is a high-purity (≥99.8%) sealing material that meets ASTM F36, F38, and F43 standards for mechanical performance and chemical compatibility.

    ASTM-Compliant Performance Features

    1. Compressive Strength
      • Exceeds ASTM F36 requirements with a minimum yield strength of 50 MPa, ensuring reliable sealing under ASME B16.5 flange pressures up to 250 bar.
      • Compression set ≤12% after 24 hours at 150°C/10 MPa (ASTM F38).
    2. Chemical Resistance
      • Passes ASTM D543 testing for compatibility with acids (H₂SO₄), alkalis (NaOH), and hydrocarbons, making it suitable for ISO 9001-certified chemical processing plants.
    3. Thermal Stability
      • Operates within ASTM E136 limits (-200°C to +1650°C), maintaining dimensional stability under rapid thermal cycling (ASTM C177 for thermal conductivity).

    Applications in ASTM-Regulated Industries

    1. Oil & Gas Pipelines
      • ASTM F43-compliant gaskets for flange connections in API 6A wellheads, ensuring leak-free performance in H₂S-containing environments.
    2. Power Generation
      • Composite gaskets with stainless steel inserts (ASTM A240) for steam turbines, meeting ASME BPVC Section VIII requirements.
    3. Pharmaceutical Equipment
      • FDA-listed materials (ASTM F1877) for diaphragm valves, ensuring compliance with cGMP regulations.

    Custom Specifications with ASTM Compliance

    • Dimensions:
      • Rolls: 1000mm/1500mm width, 30m/50m/80m length (ASTM F137 width tolerance ±0.5mm).
      • Sheets: 1000mm x 1500mm, thicknesses from 0.15mm (precision seals) to 5mm (heavy-duty applications).
    • Density: 0.8–1.25 g/cm³ (customizable to ASTM F36 Class 1/2/3 requirements).
    • Special Features:
      • Laser-cut profiles with ±0.1mm accuracy (ASTM F788) for complex flange geometries.
      • PTFE-coated variants meeting ASTM D1710 for halogenated media resistance.

    Testing & Certification

    • Full compliance with ASTM F36, F38, F43, and F137 standards, supported by SGS-tested certificates.
    • RoHS/REACH compliant, with traceability to conflict-free graphite sources (ASTM D7685).
    • Available with ASME BPVC Section VIII U-Stamp for pressure vessel applications.
