    API Standard Flexible Graphite Sealing Material

    Products Description

    API - Compliant Flexible Graphite Sealing Solutions

    Product Overview

    Flexible graphite materials, including sheets, foil, paper, tape, and strips, are advanced sealing materials engineered to meet API (American Petroleum Institute) standards for critical industrial applications. These materials are derived from natural graphite flakes through a two - stage process: chemical intercalation followed by thermal exfoliation. This process transforms raw graphite into worm - like structures with an ultralow bulk density of approximately 3 kg/m³. The expanded graphite is then compressed into binder - free rolls or sheets, ensuring a purity level exceeding 99.8% and exceptional performance in harsh environments.

    API - Specific Performance Features

    1. Extreme Pressure & Temperature Resistance
      • Complies with API 6A (wellhead equipment) requirements, withstanding pressures up to 10,000 PSI and temperatures ranging from cryogenic (-200°C) to 3,000°C.
      • Demonstrates <5% creep relaxation under sustained load at 150°C/API RP 521 recommended conditions.
    2. Chemical Compatibility
      • Meets NACE MR0175/ISO 15156 for sour gas environments, resisting sulfide stress cracking in H₂S - containing media.
      • Tested to API 607 fire resistance standards, maintaining integrity during hydrocarbon fires (ASTM E162 radiant panel test).
    3. Mechanical Reliability
      • Compressive strength of 60 MPa ensures structural stability in API 6D pipeline valves.
      • Self - lubricating properties reduce torque requirements in API 602 compact gate valves.

    Applications in API - Regulated Industries

    1. Oil & Gas Sealing
      • Used in API 6A wellhead gaskets, providing reliable seals in high - pressure/high - temperature (HPHT) drilling operations.
      • Composite versions with stainless steel inserts meet API 17D for subsea equipment.
    2. Refinery & Petrochemical
      • API 600 gate valve seals resist aggressive chemicals (e.g., sulfuric acid, hydrocarbons).
      • Flame - resistant gaskets comply with API 521 泄压 device standards.
    3. Power Generation
      • API 610 centrifugal pump seals maintain leak - free performance in boiler feedwater systems.
      • Graphite - metal hybrid designs meet API 617 axial compressor requirements.

    Custom Specifications for API Compliance

    • 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 (customizable for API 6A trim components).
    • Special Features:
      • Laser - cut profiles for API 609 butterfly valve seats.
