Before you pull the trigger on a natural gas or propane fire pit or burner, make sure you have the desired capacity for fuel. For instance, a 1/2" pipe coming directly from a natural gas meter could not be over 10' long and handle the volume of a 10hp generator. Right from the meter a. 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.

Sizing. Gas piping shall be sized in accordance with one of the following: 1. Pipe sizing tables or sizing equations in accordance with Section 2. The tables cover pressures up to 50 pounds(psi) for schedule 40 pipe materials and up to 5 pound for semi-rigid tubing and Corrugated Stainless Steel Tubing . Calculate capacities and dimensions of natural gas pipe lines. The specific gravity of natural gas varies from to Typical values are in the range.

The sizing of a 2 psi ( kPa) gas piping system is performed using the traditional Longest Length Method but with modifications. The 2 psi ( kPa) system. This handout will guide you thru the basic, most common method for sizing a natural gas piping system for residential or commercial application. 2PSI Service Pressure 2 PSI Systems work on 2 stages, the first stage starts at the gas meter or LPG tank regulated at 2 psi and ends at the Pounds to Inches.
