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

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
