High temperature resistant toothed composite gasket HLGR hot series
The non-metallic composite layer of the high temperature resistant toothed composite gasket HLGR hot series is made of Canadian DURLON HT1000 high temperature oxidation resistant fiber tape and Germany SGL APX II (or France Capone Roland丨600) special oxidation resistant flexible graphite composite as shown in the figure below . DURLON HT1000 high-temperature oxidation-resistant fiber tape is compounded on the inner diameter side and outer diameter side of the toothed ring surface respectively, forming a home for the special oxidation-resistant flexible graphite compounded in the middle area of the toothed ring.
The metal toothed framework of the high temperature resistant toothed composite gasket HLGR hot series is generally Ni-Crfe alloy (Inconel 600) or Ni-Fe. Alloy (Incoloy800), the material specified by the customer can also be used.
