Online calculator to quickly determine pipe sizing by velocity for air.

Compressed air line sizing calculator.

The art of calculating the right pipe size for your compressed air needs. Sizing selecting an air compressor. Here are the steps to determine the correct aluminium pipe sizing to suit your needs. Free air the compression ratio is the ratio pressure of compressed air to pressure of free air.

The required pipe size for an air compressor depends on two factors. This will increase flow rate decrease pressure drop and allow smaller line size to be used. Infinity pipe systems aluminium compressed air pipe sizing chart allows you to determine the diameter mm of the compressed air pipe main line. 250 nm3 hour is the same as 4200 nl min normal liter per minute or 150 scfpm standard cubic.

Choose the flow rate of the air compressor in the red column. Compression ratio compressed air vs. The thread size of the port on your air compressor tank does not determine the pipe size for your piping system. Air discharge through hoses discharging air volume through hoses at pressures ranging 30 90 psi.

Compressed air pipe sizing. Let s say we have a rotary screw compressor of 30 kw that can supply 250 nm3 hour normal cubic meters per hour. Starting at the air compressor and looping around your shop back to the compressor. Equations displayed for easy reference.

Gases and compressed air air lng lpg and other common gas properties pipeline capacities sizing of relief valves. Step 7 determine the compressor tank receiver size. Compressed air pressure loss in pipe lines online calculator with metric and imperial units calculate pressure drop in compressed air pipe lines metric and imperial units compressed air pipe line capacity capacities of compressed air pipelines applied pressure ranging 5 250 psi 0 5 17 bar. Steps to figuring what size piping your compressed air system needs.

This is a critical step in sizing and selecting the proper compressor. Of course you want to know the best size of pipe to install in your compressed air system. Remember that an oversize pipe compensates for possible scale build up and provides for future expansion of the overall air system. Most manufacturers offer standard sizes based on the cfm of the compressor the most popular sizes are 80 120 and 240 gallon.

The distance of the application and the volume of air being carried to the endpoint. If the pneumatic tools are located halfway across the factory floor you will need a different pipe size than you would for an application situated three feet away from the air compressor. Here s an example calculation using the compressed air pipe sizing table table 1 and the equivalent pipe length table table 2.
