Burial dept and minimum cover of underground natural gas pipes. Different pipe schedule means different wall thickness for the steel pipe in the same diameter. Therefore, the published sizing charts and reference guides for natural gas pipe in NFPA 54/ANSI Z223.1 cannot be used to size the piping of a biogas system. Of course, the higher the thickness the higher the weight, and this very important consideration can also be attained by data tables provided by the pipe manufacturer. From Piping .

When you are pushing air through too-small pipes with many bends and couplings, you can experience a significant loss of pressure between the air compressor and the ends of the lines. We don't collect information from our users. To hold the distribution loss to 1 PSI, pipes of larger diameter must be used on longer runs to carry the same flow that can be handled by smaller pipes on shorter runs. Friction Losses in Steel Pipes size 0.5 to 1.25 inch diameter. In a recent edition of pme's e-newsletter we ran a link to an extremely popular article written by Mike Frankel on sizing medical gas pipe.
