Pipe Sizing Calculator

Type one (1) gas that is going to be used in this area, or select from one of the provided drop down options.

This is the number of stations that you are currently using or have the gas staged for use.

To estimate the volume required at each work station, note the usage of gas required for various equipment and/or cutting tips and note the highest volume required.

To provide a more accurate estimate, consider how often (if ever) all stations would require this amount of gas at the same time and then reduce the calculated amount accordingly. We often use 70-80% as the factor.

EXAMPLE: If the highest volume needed from any one of ten (10) work stations is 10 scfh, the volume you would use for this field is 10. However, knowing that not all workstations need and/or will use this flow at the same time, you could use 7 or 8 as the ‘Volume Required’.

Want to calculate volumes of gas based on pounds used or other factors, here’s a great tool to help with conversions:

For this figure, you will want to use the highest/lowest?!? Needed across all the equipment/tips/outlets.

If your equipment provides a different pressure scales such as Bar, Kpa, or a scale other than pounds-per-square-inch (PSI), you can easily convert it through this link: http://www.onlineconversion.com/pressure.htm

To estimate the overall pipe length:

1) Identify where the cylinders and manifold will be located for the piping system.

2) Using building plans, tape measures, or an electronic measuring device such as the measuring app on your smart phone, measure where the pipe will be installed. This includes pipe runs up, across, and down, starting at where the cylinders will be located with a piping system and ending at each point of use.

3) After adding all these up, select the next largest value for this field.
