Flexible Graphite Ring
Product Features: Made from high-purity flexible graphite via molding or stamping, offering excellent resiliency, self-lubrication, high-temperature resistance, and chemical inertness. Binder-free, non-aging, with low thermal expansion coefficient for stable sealing performance under thermal cycling conditions.
Technical Specifications:
Pressure: 0～25 MPa
Temperature: -200 to 650 °C (oxidizing atmosphere) / -200 to 3000 °C (inert or reducing atmosphere)
Linear speed: — (mainly for static seals)
Chemical suitability: pH 0–14
Application media: high-temperature steam, hot water, hydrogen, ammonia, liquid nitrogen, liquid oxygen, organic solvents, acids, alkalis, and various corrosive chemicals (excluding strong oxidizing agents such as concentrated nitric acid, concentrated sulfuric acid, and halogens).
Applications: Widely used for static sealing in valve seats, bonnets, pump casings, reaction vessels, flanges, manways, and handholes. An ideal sealing component for high-temperature and high-pressure equipment in the petrochemical, power, metallurgical, and pharmaceutical industries.
