Spiral Wound Gasket
The Spiral Wound Gaskets are composed of a metallic continuous stripe with a special shaped profile, coupled with a continuous filling stripe (Asbestos, PTFE, Grafoil, Ceramic etc) evenly wound in concentric spiral under constant stress. The Spiral Wound Gaskets are reinforced on the inner and outer diametre by winding of several electrically welded spiral metal only.
Materials Standard materials are type 304 Stainless steel with composite Asbestos/ Graphite/ ePTFE / Mica Fillers.
