According to ASME code, what is the minimum size of pipes connecting the water column to a boiler?

The correct answer highlights that according to ASME (American Society of Mechanical Engineers) code, the minimum size of pipes connecting the water column to a boiler is specified to ensure proper performance, safety, and functionality.

Choosing a pipe size that is too small can lead to issues such as insufficient water flow, inaccurate water level measurement, and increased risk of water hammer or other mechanical failures. A pipe size of one inch is stipulated by the ASME code to maintain an adequate balance between effective water flow and safety considerations. This size allows for sufficient drainage and prevents potential blockages, which is critical in maintaining proper boiler operation at varying pressures and temperatures. Thus, one inch is recognized as the minimum requirement to ensure reliable and efficient performance in these systems.
