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.
The HSGR hot series of high temperature resistant toothed composite gaskets has two structural types:
Type A (no locating ring type, only tooth-shaped frame), suitable for Zen groove surface (TG) and concave-convex surface (MFM) flanges.
Type C (with locating ring type, tooth-shaped frame + locating ring). Suitable for raised face (RF) and flat (FF) flanges.
Type I Type II
Type A Type C
No positioning ring type, only tooth-shaped skeleton With positioning ring type, tooth-shaped skeleton + positioning ring
Suitable for tongue and groove (TG) and concave-convex (MFM) flanges Suitable for raised face (RF) and flat (FF) flanges
