Sealing behavior of bolted flange system with double metallic C-rings during prolonged high-temperature operation

Key Points

• Improved sealing behavior reduces leak rates significantly under prolonged high-temperature operation, indicating enhanced reliability.
• Leakage rates decreased by nearly 30% during tests at temperatures exceeding 300°C, showcasing the effectiveness of the C-rings.
• Assessment using mechanical property tests and thermal expansion analysis on the double metallic C-rings was conducted for performance evaluation.
• Highlights potential for increased safety and efficiency in high-temperature applications, though real-world effectiveness needs further validation.
