Die-formed Graphite Rings are made of low-sulphur expanded graphite without any fillers or binders. Die-formed Graphite Ring are compressed in precise moulding tools to the required density.Die-formed Graphite Ring is mede from the high purity of the material (>98%), no special corrosion protection is required. In general, Die-formed Graphite Ring has square section and also has V-shaped and wedge-shaped section.Die-formed Graphite Ring are suitable for high pressure sealing. Main specification of Die-formed Graphite Rings: PH Range:0-14 Temperature:-200-800℃ Non oxidizing condition Pressure:0-35MPa Velocity:10m/s Density:1.4-1.6g/cm3
