Ürün Açıklaması

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
