How do I calculate natural gas pipe size? (1) Measure the length of the pipe from the gas meter location to the most remote outlet on the system. (2) Locate that total length in the left-hand column of sizing table*, or the next longer distance where the table does not give the exact length. How many pounds of pressure is in a gas line?

Most natural gas pipes run up to a nominal size of four inches, although you can get pip that’s up to eight inches in diameter. When you see the flow for natural gas in pipes, these don’t refer to copper pipes.

Minimum Size of Piping Outlets: The size of the supply piping outlet for any gas appliance shall not be less than one- half (1/2) inch. Pipe Sizing Methods: Where the piping size is to be determined using either of the methods below, the minimum diameter

59 cubic feet per hour (from Table 1). Maximum gas demand of outlet D:99981231160000-0800 136 cubic feet per hour [150,000 Btu/hour divided by 1100 Btu per cubic foot]. Determine the length of pipe from the gas meter to the most remote outlet (outlet A) is 60 feet. Sec 1 (10) + Sec 2 (10) + Sec 3 (30) = 60

Using the next higher column labeled 90 feet on the pipe chart, we will enlarge that section and eliminate all the others for clarity to show the CFH and pipe size needed: Pipe Size 90'

160 is needed to cover this load and following the column to the top 1” will be the pipe size. • Each branch will be sized to the Table 4 90’ row. Branch 1, 30,000 BTU/hr will need .5”. Branch 2, 80,000 BTU/hr will need .75”. Branch 3, 45,000 will need .75” pipe. Branch 4 will need .75” pipe. Natural Gas Pipe Sizing Longest Length Method

While all that is accurate, it’s not the way the UPC says to size natural gas piping. Being stuck on 1,000, even when it seems to provide a margin for error, will typically mean the cubic foot/hour (CFH) of each section of pipe is knowingly designed to carry more Btus than required with the piping perhaps being larger than required.

Nominal pressure at the burner for Natural Gas is 3.5” of water column. (Typical machine supply 5”-7”) Pipe length must include additional length for all fittings. Add approximately 5 feet of pipe per fitting. Natural Gas Example: A machine with a burner that requires 440,000 BTU would need a 1 -1/4” pipe for a 20” long run.
