Filler material: PILLARFOIL™ + inorganic fiber
Spiral wound gasket with a non-penetrable layer of flexible graphite tape sandwiched by inorganic fiber tape of high restorability on the inside and outside.
This gasket can be used at temperatures of 450° or higher, where general-purpose flexible graphite spiral wound gaskets are not applicable.
Piping design (flange, bolt, etc.) is the same as that for flexible graphite spiral wound gaskets.
