Natural Gas Piping Diagram

About this detail

Natural gas distribution piping network designed in accordance with the 2015 International Fuel Gas Code. The system originates from a gas meter provided in phase 1.5 with a downstream gas pressure of 5 pounds and utilizes the longest length method with a measured length of 600 feet. The total gas demand equals 10,073 MBH and 11,314 cubic feet per hour, which includes 1,000 cubic feet allocated for future demand. The main line sizes transition from 2-1/2 inches at the meter down through 2 inches, 1-1/2 inches, 1-1/4 inches, and 1 inch to supply various equipment branches. Individual branch connections serve multiple boilers, water heaters, rooftop units, and humidifiers with pipe sizes ranging from 2 inches down to 1/2 inch.
