The gasket features a composite structure of a double-layer metal framework and flexible graphite, relying on the “pressure self-sealing” mechanism to maintain excellent sealing performance even under high-temperature conditions. The article systematically elaborates on its material process innovations, thermomechanical coupling experiments, and methods for verifying sealing integrity, and establishes a life prediction and engineering risk management system, providing a technical route and theoretical support for the reliable application of high-end sealing components in the petrochemical field in China.
