SS347 Vermiculite Spiral Wound Gaskets
Vermiculite is a natural, inorganic mineral that does not oxidize. It maintains its structural integrity and sealing properties at temperatures up to 1000°C
Description
The SS347 vermiculite spiral wound gasket is made of an SS347 V-shaped strip and vermiculite filler. This gasket can bear higher temperatures than other materials. It exhibits satisfactory general corrosion resistance that is comparable to SUS 304. The gasket was developed for use in the temperature range of 427 to 816°C.
Advantages
The SS347 vermiculite spiral wound gasket is primarily used because it solves the critical vulnerability of traditional graphite gaskets: oxidation and failure in extreme high-temperature environments. This gasket has superior resilience and thermal cycling performance.
