Graphite gaskets
Graphite gaskets for sealing the flanged joints of valves, pipelines, vessels and apparatus.
Product information
Non-reinforced gaskets are made of graphite tape 0.3–0.5 mm thick, non-reinforced graphite sheet of the required thickness and density, or graphite foil 0.5–0.6 mm thick; their diameter can reach 4000 mm. Reinforced gaskets are made of graphite sheet reinforced with perforated stainless-steel foil 0.1 mm thick; thickness 1 to 5 mm, outer diameter of ring gaskets up to 1500 mm. Compression limiters are used for heavily loaded joints, and protective devices (obturators) keep the gasket away from aggressive media and air at high temperatures.
