Description

Custom Thickness Graphite Gasket Material with Excellent Thermal Stability for Deep-Cryogenic High-Vacuum Systems Used in Petrochemical & Processing Plants

Our custom-thickness graphite gasket materials are specially developed to deliver outstanding thermal stability and consistent sealing performance in deep-cryogenic, high-vacuum operating environments, widely serving petrochemical facilities, processing plants, heavy machinery and related industrial sectors. By integrating high-purity graphite materials with reinforced composite structures and fully customizable production, we provide dependable long-term sealing solutions that meet strict engineering standards. We focus on serving factory and enterprise procurement customers, while also supporting individual purchasers — all orders are shipped exclusively from China, and individual buyers are required to bear the corresponding freight costs.

Customizable Thickness & Dimension Solutions

We provide flexible thickness and size customization to match diverse equipment assembly and installation requirements in petrochemical and processing industries.
  • Standard Thickness Series
    We offer a conventional thickness range from 1.0mm to 6.0mm, capable of satisfying most daily industrial sealing and flange assembly needs.
  • High-Strength Composite Thickness Design
    For heavy-duty working conditions requiring higher durability and structural rigidity, we adopt a 3+2 composite layered structure (Graphite-Metal-Graphite-Metal-Graphite). Through advanced multi-layer composite bonding technology, the product achieves greater thickness while retaining excellent flexibility and sealing reliability.
  • Custom Size Processing Service
    Conventional sheet dimensions include:
    500×500mm, 500×1000mm, 500×1500mm, 1000×1000mm, 1000×1500mm.
    In addition to standard specifications, we support full-size custom cutting and molding according to customer drawings and equipment-specific parameters.

Engineering Application Recommendations

Reasonable thickness selection is critical to balancing sealing performance and project cost.
For optimal results, we recommend using the thinnest applicable thickness that meets working conditions to maximize sealing efficiency.
If you need support in material selection or thickness matching, our professional engineering team offers complete technical assistance, including material property comparison tools and medium compatibility analysis guides.

Physical & Mechanical Performance Index

The following core physical performance data provides a reliable reference for engineering design and procurement selection.
Test Item Index Value
Tensile Strength (MPa, min.) ≥30
Compressibility (%) 10–20
Recovery (%) ≥35
Thickness Deviation (mm) 0.05
IRM 903# Oil Immersion (150°C × 5h) – Thickness Increase ≤10%
IRM 903# Oil Immersion (150°C × 5h) – Weight Increase ≤10%
B Fuel Immersion (21–30°C × 5h) – Thickness Increase ≤10%
B Fuel Immersion (21–30°C × 5h) – Weight Increase ≤10%

Material Characteristics & Applicable Media

Our graphite gasket material features stable chemical and physical properties, making it highly suitable for demanding industrial environments:
  • Excellent sealing performance in steam pipelines
  • Good ozone aging resistance
  • Compatible with natural gas transmission systems
  • Stable performance in deep-cryogenic and high-vacuum environments
  • Low outgassing rate, ideal for vacuum equipment in petrochemical and processing plants

Customizable Structural Configuration

To adapt to different temperature, pressure and medium conditions, we provide a variety of configurable structural combinations.
Structure Part Customizable Options Performance Improvement
Reinforced Metal Insert 0.2–0.25mm perforated metal insert;
Carbon steel (tinplate), SS201, 304, 316		 Enhances tensile strength, dimensional stability and resistance to delamination
Graphite Surface Layer Double-layer pure flexible graphite;
Carbon content optional: 95%, 97%, 98%, 99%		 High purity reduces volatile emissions; good fit for flange surfaces; improves vacuum sealing
Product Thickness & Form Standard 1.0–6.0mm;
Custom thickness and shaped parts available		 Meets special assembly clearance in petrochemical pipelines, cryogenic devices and vacuum systems

Core Performance Advantages

  • Superior Thermal & Vacuum Stability
    Maintains structural integrity under extreme temperature fluctuations and long-term high-vacuum conditions, suitable for deep-cryogenic systems and petrochemical processing units.
  • Stable Sealing & Low Compression Set
    The multi-layer composite structure effectively prevents delamination. Stable compressibility and resilience ensure long-term sealing with minimal performance degradation.
  • Strong Medium Compatibility
    Excellent oil resistance and chemical inertness make it widely applicable in hydraulic systems, pipeline flanges, fuel-related equipment and various process sealing parts.
  • Tailored Custom Solutions
    When standard products cannot meet special working conditions — such as unique deep-cryogenic pipelines, special high-vacuum chambers or non-standard dimensions — our technical team can develop customized material formulas and processing solutions.
