What is a primary concern in the sizing of fuel gas distribution piping?

The sizing of fuel gas distribution piping must prioritize pressure loss as a primary concern. When gas moves through piping, various factors, such as the length and diameter of the pipes, type of gas, and the fittings or bends in the system, contribute to the overall pressure drop. Adequate pressure is essential to ensure that appliances receive the proper amount of gas for efficient operation. If the piping is not sized appropriately, excessive pressure loss can lead to insufficient gas supply, causing appliances to malfunction or reducing their performance.

Proper sizing will account for the anticipated flow rates and the specific requirements of the connected appliances, ensuring that the gas pressure remains within acceptable limits throughout the system. Other factors like minimizing expansion, temperature control, and leak prevention are important as well, but they typically stem from the foundational aspect of managing pressure loss effectively in the design and installation of gas distribution systems.
