Reinforced Graphite Gasket Sheets for Oil and Gas Applications
Reinforced Graphite Composite Gasket with Tinplate Product Description
Premium Reinforced Graphite Gasket Sheets Built for Oil & Gas Industry Demands
Designed to excel in extreme oil and gas environments, our reinforced graphite gasket sheets combine pure flexible graphite layers with a perforated metal core (0.2–0.25mm thickness) for superior sealing under high temperatures (500°C+) and pressures. Ideal for critical applications like pipeline flanges, valve systems, and compressor seals, these gaskets ensure leak-free performance in corrosive and cyclic conditions.
Key Advantages for Oil & Gas Operations:
✓ Unmatched Durability: Dual graphite layers bonded to carbon steel, SS201, 304, or 316 stainless steel inserts eliminate delamination risks.
✓ Oil & Chemical Resistance: With 95–99% carbon purity, these sheets withstand hydrocarbon exposure, acids, and steam.
✓ Cost-Efficient Design: Optimized thickness (1.0–6.0mm) reduces material waste—select the thinnest feasible gauge for your application.
✓ Customizable Construction: Multi-layer "3+2" bonding (Graphite-Metal-Graphite-Metal-Graphite) enhances strength for thicker requirements.
