Specialized Graphite Sealing Gasket of Custom Thickness

 

For High-Vacuum Deep-Cooling Systems in Petrochemical Refineries & Heavy Industrial Plants

 

Products Description

 
Cling-Seal custom-thickness graphite gaskets are engineered specifically for high-vacuum, deep-cooling, and high-pressure operating environments in petrochemical refineries, chemical plants, and heavy industrial facilities. Built from high-purity expanded graphite with precision lamination and customizable forming, this series delivers reliable, long-term sealing performance under extreme temperature fluctuations, corrosive media, and ultra-low outgassing requirements.
 

Manufacturing Process

 
Produced from high-purity natural graphite flakes, our material undergoes chemical intercalation followed by rapid thermal expansion at 800–1000°C, creating worm-like expanded graphite with a bulk density of approximately 3 kg/m³. Without binders or chemical additives, the exfoliated graphite is compacted into rolls or sheets to achieve stable performance and carbon purity above 99%. This structure ensures excellent flexibility, thermal stability, and vacuum compatibility for critical industrial sealing systems.
 

Product Range

 
We provide a full suite of flexible graphite products for custom gasket fabrication, including:
 
  • Expanded graphite sheets
  • Graphite foil
  • Graphite tape
  • Graphite strips
  • Graphite paper

Key Performance Benefits

 
  • Extreme Thermal & Vacuum Stability
     
    Stable performance from deep-cooling cryogenic temperatures up to high-temperature service; low outgassing ideal for high-vacuum systems.
     
  • Superior Chemical Resistance
     
    Resists acids, alkalis, hydrocarbons, and corrosive media commonly found in petrochemical and refining environments.
     
  • Strong Mechanical Reliability
     
    High compression recovery and low stress relaxation ensure leak-free performance under pressure cycling and long-term service.
     
  • Custom Composite Design
     
    Can be laminated with stainless steel or copper alloys for reinforced structural gaskets suitable for heavy-duty flanges and valves.
     
 

Typical Applications

 
  • Dynamic shaft seals and packing rings for pumps, valves, and compressors
  • Custom die-cut flange gaskets for pipelines, reactors, and pressure vessels
  • High-vacuum chamber seals and thermal barriers in deep-cooling systems
  • Heavy industrial seals for refineries, processing plants, and energy equipment
