Metal spiral wound gaskets are precision-engineered sealing solutions designed for high-performance applications where reliable sealing under extreme conditions is crucial. Constructed from alternating layers of metal and filler material, these gaskets provide exceptional resilience and durability.
Advantages:
Applications: Metal spiral wound gaskets are ideal for sealing flanges in pipelines, valves, pumps, heat exchangers, and other equipment in demanding industrial environments.
Material Selection: Commonly used materials include stainless steel, carbon steel, and various alloys. Filler materials such as graphite, PTFE, and ceramic are chosen based on the specific application requirements.
