A spiral wound gasket (20) is disposed between joint members (22, 24) of a hot fluid joint to seal a gap (48) therebetween. The spiral wound gasket (20) includes a first high temperature performance metallic strip (28) formed of a thermally conductive alloy, including, Ni Cr, and Fe, spirally wound around a central axis (A) to present a first high temperature performance metallic winding (30) exposed to hot fluids. A first non-metallic filler strip (32) formed of a mica material is spirally wound outwardly of the first high temperature performance metallic winding (30) to form a first non-metallic filler winding (34). A second high temperature performance metallic strip (36) formed of a stainless steel material is spirally wound outwardly of the first non-metallic filler winding (34). A second non-metallic filler strip (40) formed of a graphite material is spirally wound outwardly of the second high temperature performance metallic winding (38). |
