PIPE SIZING CHART Natural Gas : Pipe Sizing Chart

1 Natural Gas : Pipe SIZING ChartLiquid Propane : Pipe SIZING ChartLiquid Propane (LP) Gas flow is given in thousands of BTU/hr. - One cubic foot of LP gas - 2516 BTUThis CHART refers to low pressure LP, after regulation, Standard nominal pressure at the burner for Liquid Propane Gas is 11 of water length must include additional length for all fittings. Add approximately 5 feet of pipe per Example: A machine with a burner that requires 440,000 BTU would need a 1 pipe for a 20 long Gas (NG) flow is given in thousands of BTU/hr. - One cubic foot of LP gas - 1000 BTUN ominal pressure at the burner for Natural Gas is of water column.

2 (Typical machine supply 5 -7 )Pipe length must include additional length for all fittings. Add approximately 5 feet of pipe per Gas Example: A machine with a burner that requires 440,000 BTU would need a 1 -1/4 pipe for a 20 long : The SIZING charts above list the specific pipe sizes required for the amount of BTU s for a new gas line installations. If you are using an existing gas line you must take into consideration the 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.
