Pipe Sizing Spreadsheet Application

NATURAL GAS - STEEL PIPE up to 150 mm - OPERATING PRESSURE up to 75 mbar

This free spreadsheet is to help with the sizing of new steel pipe legs on low pressure natural gas systems. Enter the leg name, length, number of fittings, gas flow rate and the maximum pressure drop (ΔP) you want across the leg. The spreadsheet will then give an estimate nominal diameter yielding a pressure loss no greater than the value you specified. It requires Microsoft Excel 2010 or later. You may be prompted to enable editing and macros. Always double-check any results obtained and do not use the spreadsheet for systems outside the scope specified above.

Save the blank workbook as read-only so you can re-use it. Save individual projects under different names.

We also produce a much more functional spreadsheet application which can be used for extensions to existing installations and all pressure ranges for natural gas and LPG propane in steel, PE and copper pipe. It is provided free as part of our pipe sizing training course. More details on this course can be found near the bottom of the commercial page
