TABLE I
GAS UTILIZATION STANDARDS
HOUSE PIPING
SIZING HOUSE PIPING
Computing Sizes of House Piping (Example for Steel)
Gas piping shall be of such size as to provide a supply of gas sufficient to meet the maximum
demand of all appliances. The following procedure should be used to compute house piping sizes
from the 0.3" W. C. tables:
1. Determine the gas demand in cubic feet per hour for each outlet by using the
nameplate input rating adjusted for high altitude using the formula described under
"Appliance Input Ratings ".
2. Measure the length of piping from the gas meter to the housing piping outlet which is
the farthest from the meter.
3. Select the horizontal line showing the farthest distance or the next longer distance if
the table does not give the exact distance. This horizontal line (farthest distance) shall be
used. in sizing all sections of pipe in the piping system.
4. Starting at the farthest outlet from the meter, find the gas demand for that outlet. If
the exact gas demand figure is not shown, choose the next largest figure in the same
horizontal line.
5. Opposite this demand figure (in the column headed "Nominal Iron Pipe Size -Inches")
the minimum size of pipe to be used is indicated. This pipe size is only for that section of
pipe carrying the gas demand for the outlet under consideration.
6. Proceed in a similar manner for each outlet
7
7. After each outlet has been sized, then size each section of pipe carrying the gas
demand for more than one outlet. This is done by determining the total gas demand
supplied by each section and using that figure in the farthest distance horizontal line as
determined in step (3).
House Piping Capacity Table
The table on the following page shall be used for sizing house piping in the City of Pueblo.
