What is the typical action taken when maintenance or adjustments are made to safety valves?

1. Testing the system pressure

2. Recording performance metrics

3. Calibrating the settings

4. All of the above

The correct answer is: All of the above

When maintenance or adjustments are made to safety valves, it is common practice to conduct a comprehensive approach that often includes several key actions. First, testing the system pressure is crucial to ensure the safety valve will operate correctly under the expected conditions. This helps to verify that the safety valve opens at the designated pressure level, ensuring it can relieve excess pressure, which is vital for preventing dangerous over-pressurization. Second, recording performance metrics is an important step. This documentation is essential for maintaining a history of the valve's performance over time, which aids in identifying patterns or potential issues that may arise, ensuring regulatory compliance and contributing to overall safety practices. Lastly, calibrating the settings is a critical action taken. Calibration ensures that the safety valve operates accurately according to its specified setpoints. This involves adjusting the valve to ensure it opens at the right pressure and closes properly, which is essential for maintaining the safety and operational integrity of the system. Collectively, these actions - testing system pressure, recording performance metrics, and calibrating settings - form a comprehensive approach to maintaining safety valves, thereby ensuring they function correctly and reliably in the protection of the boiler system.
