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. NOTE: The sizing charts above list the specific pipe sizes required for the amount of BTU’s for a new gas line installations.

Sizing low pressure natural gas pipe lines - Imperial units. The tables below can be used for natural gas pipe sizing. For natural gas the nominal BTU/ft3 varies from about 900 to 1100 BTU/ft3. In general it is common to set. - free apps for offline use on mobile devices.

Gas piping should be sized in accordance with the tables in the Standard Gas Code or by other engineering methods approved by local Authority Having Jurisdiction. How to size gas piping. The Gas Code contains sizing tables and information that must be used to size most gas systems.

Calculate capacities and dimensions of natural gas pipe lines. For natural gas the nominal BTU/cf varies from about 900 to 1100 BTU/cf. In general it is common to set. The specific gravity of natural gas varies from 0.55 to 1.0. Typical values are in the range 0.6 - 0.7.

Choose your length and size from the drop down menus below. The maximum allowable BTU/Hr will be visible where the two lines intersect. This chart is based on low pressure natural gas (14" W.C.) with a dynamic pressure drop of no more than .30" W.C. in thousands.

Apr 19, 2024 · 4. Use Gas Pipe Sizing Charts. Once the equivalent length is determined, use gas pipe sizing charts provided by relevant codes or standards, such as the International Fuel Gas Code (IFGC) or the National Fuel Gas Code (NFPA 54), to determine sizing.

Natural Gas flow is given in thousands of BTU/hr. - One cubic foot of LP gas = 1000 BTU. 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 …

The tables and diagrams below can be used to size natural gas pipes with pressures above 5 psi (35 kPa) . For full table - rotate the screen!

consult with a local gas professional to determine accurate btu availability. Use this chart as a guideline ONLY and does NOT account for variations in the type of pipe (plastic or iron.)

existing gas line capacities to ensure you will have proper pressure. This chart is for reference only, we recommend you consult with a Licensed Plumber/Gas Fitter or NFPA54 (National Fuel Gas Code - current edition) for more details.
