What is a critical aspect covered in the B-51 code related to boilers?

The B-51 code particularly emphasizes boiler design and construction, with a strong focus on safety, performance, and reliability. One critical aspect covered in this code pertains to water gauge specifications, which are essential for monitoring the water level within a boiler system. Proper water gauge specifications ensure that operators can accurately assess and maintain the appropriate water level, which is vital for safe operation and preventing issues such as overheating or boiler explosions.

Water gauges and their specifications are key components in ensuring that the boiler operates within designed limits, thus contributing to the overall safety and efficiency of the system. Accurate water level indications help operators take necessary actions to maintain safe operating conditions, making this aspect crucial within the framework of the B-51 code.
