Reinforced Graphite Composite Gasket with Tinplate Product Description
Reinforced Graphite Gasket Sheets for Pipeline and Valve Sealing Engineered for critical pipeline and valve applications, our reinforced graphite gasket sheets deliver superior sealing performance in extreme environments. Designed with a 0.2-0.25mm perforated metal core sandwiched between two layers of pure flexible graphite, these sheets combine high-temperature resistance (up to 1,000°C) with exceptional durability, making them ideal for steam cycles, exhaust systems, and high-pressure industrial processes.
Key Features for Pipeline & Valve Sealing
Dual-Layer Construction: Two flexible graphite layers bonded to a corrosion-resistant metal insert (carbon steel/tinplate, SS201, 304, or 316) ensure structural integrity and prevent delamination.
Wide Temperature Range: Withstands thermal fluctuations from -200°C to +1,000°C, suitable for cryogenic to high-heat applications.
Chemical Resistance: Resistant to oils, solvents, and aggressive chemicals, ensuring long-term reliability in demanding conditions.
Customizable Thickness: Available in 1.0-6.0mm standard sizes, including multi-layer configurations (e.g., 3+2 Paper-Metal-Paper composites) for specialized needs.
Precision Manufacturing: ISO 9001-certified production ensures consistent quality and dimensional accuracy.
Global Compliance: Meets ASME, API, and EN standards, trusted by leading industrial suppliers worldwide.
Applications
Pipeline flange sealing in oil & gas, petrochemical, and power generation sectors.
Valve assemblies in steam turbines, boilers, and exhaust manifolds.
High-temperature gaskets for cylinder heads, pumps, and heat exchangers.
