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

Customizable Thickness & Dimension Solutions

• 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

Physical & Mechanical Performance Index

Material Characteristics & Applicable Media

• 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

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.
