The use and performance of flexible graphite wound gaskets
Flexible graphite wound gaskets are pure graphite products made of natural scaly high-carbon graphite, processed and refined after special chemical and physical treatments. In addition to completely maintaining the excellent characteristics of natural scaly graphite, it also has the main characteristics of softness, resilience, corrosion resistance, high pressure resistance, radiation resistance, and thermal conductivity. The material is woven from low-sulfur expanded graphite thread and reinforced with cotton lining. Has a very low friction coefficient, will not wear the pump shaft and valve stem, and has good thermal conductivity, chemical resistance and high resilience. The graphite graphite wound gasket root is made of flexible graphite composite coil. Mainly used for static and dynamic sealing of valves, pumps and pipeline connections. This product has the characteristics of wide applicability, high temperature resistance, strong acid resistance, strong alkali, long life, self-lubrication, bottom friction coefficient, etc., and is especially suitable for use in harsh medium conditions.
Graphite wound gaskets are widely used in hydrogenation equipment under severe working conditions such as hot water, steam, oil, high temperature and high pressure.
