What is the maximum size of the pipe used for surface blow-off?

1-1/2 inches
2 inches
2-1/2 inches
3 inches

The correct answer is: 2-1/2 inches

The maximum size of the pipe used for surface blow-off in low pressure boilers is indeed 2-1/2 inches. This specification is important to ensure effective removal of impurities without compromising the system’s integrity. A blow-off pipe of this size allows for adequate flow rates while maintaining pressure and temperature control within the boiler system. Understanding the limitations on pipe size is crucial for safe operation, as larger diameters could introduce excessive flow, potentially causing loss of pressure or creating operational inefficiencies. Therefore, adhering to the specified diameter helps in preventing operational issues and is in line with safety regulations. Other sizes, while they may seem plausible, exceed the maximum recommended dimensions, which can lead to complications like water hammer or increased wear on the system, thus underscoring the importance of using the proper size for surface blow-offs.
