| High Light | 316L Spiral Wound Gasket ，Flexible Graphite Filled Gasket ，CGI Type ASME B16.20 Gasket | ||
Spiral wound gasket manufactured to ASME B16.20 with a 316L centering ring, a 316L inner ring and flexible graphite filler. Built for steam, chloride-bearing and thermally cycled service where mixed-material gaskets typically fail at the outer ring first.
Three components: a 316L centering ring that locates the gasket on the flange face and limits compression; a spiral-wound sealing element of pre-formed 316L strip and flexible graphite filler; and a 316L inner ring that prevents inward buckling of the winding and shields the sealing element from process-fluid erosion.
316L is the low-carbon grade of 316 (C ≤ 0.03%). It resists sensitization and the intergranular corrosion that standard 316 can develop after welding or heat exposure, and its molybdenum content gives pitting and crevice corrosion resistance in chloride and marine environments. With both rings in 316L, no carbon-steel component remains to corrode.
Flexible graphite is chemically inert and non-aging. Service range −200 °C to +450 °C in oxidizing media, up to 650 °C in steam. High recovery under pressure and temperature cycling, low creep relaxation, and it conforms to minor flange surface irregularities.
