Reinforced graphite gasket is cut from pure graphite sheet or graphite sheet with metal reinforcement, features excellent corrosion-resistance, high-and-low temperature resistance, good compression resilient and high internsity.
it can be used as sealing elements of pipe, valve, pump, pressure vessel, heat exchanger and condenser, etc.
Other complex gaskets such as water gauge gasket and flange gasket with bolt holes are available. Wrapped with metallic stripe in the inner and outer circle borderline.
Application & Properties:
Various shapes are available, used in petrochemical, mining, vessels, boilers, piping and duct, pumps and valves, flanges etc. Suitable for steam, mineral oils, heat transfer oils, hydraulic oil, fuel, water, seawater, freshwater etc.
