Piping is a vital component in a compressed air system.
Piping systems more than five years old have been shown to exhibit leaks of up to 25 percent yet many facilities are slow to upgrade equipment to the latest technology.
Metal pipe can be black iron copper stainless steel or extruded aluminum alloy.
Guide to compressed air piping systems last updated on.
One of the simplest fixes in a compressed air system is to replace tee connections with directional angle entry connections.
Pressure loss through piping.
Inefficient compressed air distribution systems result in higher energy bills lower productivity and poor air tool performance.
Now instead of giving you complicated formulas to calculate the pressure drop here is a simple table that will answer all your pipe sizing questions.
Compressed air piping systems michael frankel cipe utility systems consultants somerset nj introduction compressed air is an often used utility system found in facilities.
Excessive velocity can be a root cause of backpressure erratic control signals turbulence and turbulence driven pressure drop.
Now measure or calculate the total length of your compressed air pipes and look it up in the top row.
Along the way there is a risk of contamination and pressure drops.
In a piping system where a feed line of compressed air is trying to feed into another air line the turbulence caused by a 90 entry can cause a 3 to 5 psi pressure loss which increases the operating costs.
Once air is compressed dried and filtered it is sent to an end use.
Keep these five factors in mind when designing your compressed air piping system to help minimize risk of dirty or poorly pressurized air.
Compressed air pipe size table.
Occasionally a large pressure drop in the piping system is compensated by adjusting or increasing the working pressure of the compressor from for example 7 bar to 8 bar.
Condensate load from compressed air.
The british compressed air society suggests that a velocity of 20 fps or less prevents carrying moisture and debris past drain legs and into controls.
