Metal winding gasket manufacturing process
Metal wound gaskets, commonly referred to as spiral wound gaskets, are one of the most widely used static sealing components in industrial applications. These gaskets typically consist of a metal tape with a "V" shaped cross-section and non-metallic filler material, wound alternately around a central core. This unique structure allows them to provide multiple sealing functions, offering excellent resilience, strong adaptability to different media and temperatures, and a wide pressure range. Additionally, they require low pre-tightening force and can absorb vibrations and impacts, making them ideal for use in various industries such as chemical, power generation, and nuclear energy.
Since their introduction into China in the early 1960s, metal wound gaskets have become an essential part of many industrial systems. However, domestic production still faces challenges, including outdated manufacturing equipment, low labor efficiency, high costs, and inconsistent quality due to generalized processes that do not account for varying pressure levels. Improvements in design, materials, and production methods are continuously being explored to enhance performance and reliability.
A reliable seal is crucial in industrial settings, especially in petrochemical plants where seal failures can lead to significant waste, environmental pollution, and even serious safety hazards. In fact, up to 80% of unplanned maintenance work in such facilities involves seal repairs. As a result, there is growing demand for hydrostatic seals that offer minimal leakage, high reliability, long service life, and broad applicability.
