Engine graphite seal ring - manufacturers supply

Since graphite seal - County of Hebei Mei Chen sealing materials Co., Tel: 13831607639 Miss Han, or 15832683686 Manager Xu. From high grade pure flexible graphite paper, sheared after in the mold pressed by the spiral-wound ring packing. In general, a square cross-section, may also be in the form of V-shaped wedge, the latter two apply high pressure area. Depending on requirements, plus 304 stainless steel mesh, nickel screen, copper, asbestos cloth, aluminum foil and other materials inside the graphite packing rings can be improved pressure resistance. Graphite packing ring seal material should have excellent various properties, used alone or in combination with other fillers, especially for high temperature and pressure of the static sealing member. For: pump, valve packing. For compressors, pumps, valves, chemical instruments and meters. For industry: oil equipment, power plants, chemical, steel and other sectors for the media: adapt to hot water, high temperature, high pressure steam, heat exchange fluid, ammonia, hydrogen, organic solvents, hydrocarbons, cryogenic liquid and other media. Performance and features flexibility, high self-lubricating, high coefficient of restitution, chemical stability, good corrosion resistance, can provide effective technical parameters graphite packing ring seal: Pressure (Pressure) 25Mpa Temperature (Temperature) - 200-850 ℃ line speed 0-30m / s PH value 0-14 density 1.4-1.9g / cm3
