Graphite Mould Ring, adopting high-quality flexible graphite, or graphite and asbestos tape with wire, net and various enhanced packings, is compressed into the required size by molds. With good elasticity and corrosion resistance, the structure will not be eroded by chemical media. The ring has good sealing effect without any torque loss of bolts. Graphite Mould Ring is generally used after combination with end ring, which is determined by service conditions, to prevent from being squeezed out. Graphite Mould Ring can be used to seal hot water, high-temperature and high-pressure steam, heat exchange fluid, hydrogen, ammonia, organic solvents, hydrocarbons, low-temperature liquid (LN, LHe, LNG, LPG, etc.), etc.
