Need help to calculate pipe size for nitrogen gas (from tank to pressure regulator). These may be momentary peaks of demand generated by dust collector blow-down valves, cylinder/ram actuation, diaphragm pumps or other systems that use short, intense bursts of air. A gas meter can be used at gasket and seal locations to detect escape of gases. The NASA document referenced by btrueblood has a pipe line velocity of 100 fps. 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. Likewise, if the system only handles 80 PSI, the pipe should be expected to carry lower volumes of air at one percent loss. Plastic pipe is corrosion resistant but not recommended as this material does not have the necessary tensile strength and can be statically charged. Larger pipes store more air; 500 feet of 1 pipe will store about 18 gallons of air, while 500 feet of 2 pipe will store about 77 gallons. For the sizing of the pipes of an oxygen system, can I use the same chart of the compressed air pipe sizing? Oxy Acetylene Cutting Torch Pressure Settings: Get Your Oxygen In comparison, biogas piping prior to conveyance (with a blower, compressor), or gas storage, is considered low pressure piping and is designed differently. Friction loss in air hoses vs. operating pressure. Instrumentation can sense this has occurred and notifies operators that biogas is being released to the atmosphere outside of a controlled flare, and/or can shut down any blowers or compressors to avoid additional air entrainment in vacuum conditions.
