Carbon graphite products are indispensable and crucial components in modern high-efficiency machinery. Depending on different process conditions and friction pair materials, various specifications of carbon-graphite sealing rings, graphite expansion rings, blades, graphite bearings, bushings, and washers can be matched with different materials and impregnated with various substances. They have been successfully applied in low-temperature, high-temperature, vacuum, high-pressure environments, various rotational speeds, and a range of corrosive, flammable, explosive, and toxic media. They serve as ideal components and materials under dry, semi-dry, and liquid friction conditions. As a result, they are widely used in machinery, petroleum, chemical engineering, fertilizers, synthetic rubber, instrumentation, hydraulic transmission equipment, and other industrial sectors.
