What should be replaced when a flanged joint is opened?

• A. Gasket
• B. Sealant
• C. Ring
• D. Nut

Answer: (A)

When a flanged joint is opened, the gasket should be replaced. This is because the gasket forms a seal between the two flanges to prevent leaks. Over time, especially after being compressed and subjected to operational conditions such as temperature changes and pressure fluctuations, gaskets can become degraded, compressed, or deformed. Reusing an old gasket can lead to improper sealing and can create safety hazards due to leaks. Replacing the gasket ensures that the joint is sealed properly, providing safety and maintaining the integrity of the system. Regular maintenance practices typically include gasket replacement to uphold the safety and reliability standards necessary in propane gas systems.
