"Why can spiral wound gaskets withstand high temperatures and high pressures?" "What do the differences between graphite, PTFE, and fillers signify?" "What should be considered when selecting the material for the hoop?" The "spiral wound gasket," which boasts overwhelming reliability under harsh conditions such as in power plants and petrochemical plants. The secret to its excellent sealing performance lies in its intricate spiral structure, which alternates between a V-shaped metal strip "hoop" and a cushioning material "filler." These two components serve as the skeleton and muscles of the gasket, and correctly understanding and combining their respective roles and materials is the key to effectively utilizing spiral wound gaskets. *For more detailed information, please refer to the related links.
