304 metal spiral wound gasket is primarily made of 304 stainless steel material, typically featuring a spiral winding structure with flexible fillers such as graphite or PTFE. Its spiral winding design provides excellent elasticity, allowing deformation under bolt preload to fill microscopic irregularities on flange surfaces, thereby achieving effective sealing. The 304 stainless steel material offers good corrosion resistance, making it suitable for water, steam, oils, and various chemical media. The gasket has a wide operating temperature range, generally usable from -196°C to 700°C (specific conditions depend on actual media and pressure parameters). Another notable characteristic is its superior resilience, which maintains sealing performance even under temperature fluctuations or pressure variations. It should be noted that the gasket's performance is influenced by winding density, material compatibility, and operational conditions, so selection must be based on actual requirements.
