During boiler maintenance, replacing a failed tube is part of which category of action?

Explanation:
When a tube has failed, the appropriate action is to replace it to restore the boiler’s safe and efficient operation. A failed tube means the heat-transfer path and pressure boundary are compromised, so a permanent fix is needed rather than a temporary measure. Patch jobs are intended only as short-term stopgaps and can’t guarantee long-term reliability under boiler operating conditions. Routine inspection focuses on checking and recording the condition, not performing the repair. Reheater adjustment relates to optimizing steam temperature and flow, not repairing a damaged tube. Therefore, replacing the failed tube is the direct, proper category of action to restore integrity and performance.
