L. P. Gas piping sizing

bean

Can anyone offer some assistance on helping me size L.P. gas line for higher pressure systems? (10 -90 psi) Also on lower pressure systems (11 " W.C.) Thanks for the help!!

90 psi? Is this a commercial system and if so are you planning vaporizers? and yes..either message me or post it here we can work out the line sizing easy enough..

For normal piping setups you can just use the chart in the fuel code. https://codes.iccsafe.org/public/document/IFGC2018/chapter-4-gas-piping-installations

If you want to figure out odd ones, try using the enginnering tool box for natural gas and change the specific gravity to 1.5 for propane.
