Descripción de producto

Tailored Thickness Flexible Graphite Gasket with Superior Heat Stability for Deep-Cooling Vacuum Systems in Petroleum & Industrial Processing Facilities

 

Products Description

 
Cling‑Seal flexible graphite gaskets with tailored thickness are purpose-built to perform reliably in harsh operating environments, especially deep‑cooling circuits and high‑vacuum systems widely used in petroleum refineries, chemical plants, and general industrial processing facilities. Combining high purity, exceptional thermal stability, and fully customizable dimensions, our products provide long‑lasting, leak‑tight sealing performance under extreme temperature, pressure, and corrosive conditions.
 

Manufacturing Process

 
Our graphite material starts with high‑purity natural graphite flakes, which are chemically intercalated then rapidly thermally expanded at 800–1000°C. This process creates worm‑structured expanded graphite with a bulk density of approximately 3 kg/m³. Without binders or chemical additives, the expanded graphite is compacted into rolls or sheets, delivering consistent performance and carbon purity above 99% — ideal for vacuum compatibility and low outgassing.
 

Product Portfolio

 
We offer a full range of flexible graphite products to support custom gasket manufacturing and on‑site processing:
 
  • Expanded graphite sheets
  • Graphite foil
  • Graphite tape
  • Graphite strips
  • Graphite paper
 

Standard Specifications

 
We provide standardized coil and sheet configurations to fit diverse cutting, stamping, and assembly requirements.

Key Performance Advantages

 
  • Superior Thermal & Vacuum Stability
     
    Stable performance from deep‑cooling low temperatures to high‑temperature cycling; low outgassing and excellent dimensional stability for high‑vacuum environments.
     
  • Strong Chemical Compatibility
     
    Resists acids, alkalis, hydrocarbons, and petroleum media; low sulfur and chlorine prevent alloy corrosion in critical processing equipment.
     
  • Excellent Mechanical Sealing Performance
     
    High compressibility and rebound ensure tight sealing even on imperfect flange surfaces; stable under pressure fluctuations and long‑term service.
     
  • Customizable Composite Structure
     
    Can be laminated with stainless steel or copper alloy for reinforced gaskets, improving strength for heavy‑duty flange and valve applications.
     
 

Typical Applications

 
  • Dynamic sealing: shaft packing, valve stem seals, and pump seals
  • Custom flange gaskets for pipelines, pressure vessels, and reactors
  • Sealing components for high‑vacuum chambers and deep‑cooling systems
  • Thermal barriers and static seals in petroleum and heavy industrial facilities
 

Cling-Seal Supply & Service Terms

 
  • Primary Customers: Mainly overseas corporate buyers, factory procurement teams, engineering contractors, and OEM industrial clients.
  • Shipping Location: All products shipped exclusively from China.
  • Individual Buyers: Orders are accepted only if buyers cover the full international freight cost for single‑piece dropshipping. Orders cannot be processed without confirmed freight arrangements.
