A common indication of boiler tube failure is the occurrence of water or steam leaks, as well as noticeable changes in boiler pressure or temperature. When tube integrity is compromised, it can lead to leaks, allowing steam or water to escape. This can result in fluctuations in pressure and temperature, as the system works harder to compensate for the loss of steam or water. Identifying leaks or shifts in pressure and temperature is crucial for maintaining safe boiler operation and preventing more significant issues, including safety hazards or system breakdowns.

While excessive fuel consumption may suggest inefficiencies in the boiler system, it is not a direct indication of tube failure. Low water levels can indicate other operational issues, such as pump failure or improper water feed, but they are not specifically tied to tube integrity. Noise during operation could indicate various mechanical issues but does not specifically point to tube failure. Therefore, monitoring for leaks and changes in pressure or temperature is vital for diagnosing potential tube failure in a boiler system.
