According to NFPA 54, which table is referenced for sizing piping?

The correct reference for sizing piping according to NFPA 54 is found in Table 6.3 A through M. This table provides the necessary data and formulas for determining the appropriate pipe sizes based on the specific gas type, length of the run, and the demand of the gas appliances being served.

Selecting the correct pipe size is crucial for ensuring that gas is delivered efficiently and safely throughout a system, which is vital for proper appliance operation and safety. Table 6.3 is structured to help designers and installers correctly size the piping to maintain proper gas pressure and flow rate, preventing issues such as backpressure and insufficient gas supply to appliances.

The other tables mentioned provide information on different aspects of gas installation, but they are not specifically focused on pipe sizing. This emphasizes the importance of using the correct resources and following established guidelines when working with gas systems.
