The purpose of the
Compressed Air Piping is to deliver compressed air to the points of usage. The compressed air needs to be delivered with enough volume, appropriate quality and pressure to properly power the components that use the compressed air. Compressed air is costly to manufacture. A poorly designed compressed air system can increase energy costs, promote equipment failure, reduce production efficiencies, and increase maintenance requirements. It is generally considered true that any additional costs spent improving the compressed air piping system will pay for themselves many times over the life of the system.
Condensate ControlCondensation control must be considered when installing a compressed air piping system. Drip legs should be installed at all low points in the system. A drip leg is an extension of pipe below the airline, which is used to collect condensate in the pipe. At the end of the drip leg a drain trap should be installed. Preferably an automatic drain should be used (see drain valves section of this catalogue for a complete description of the type of drain valves available).
To eliminate oil, condensate, or cooling water (if the water-cooled after cooler leaks), a low point drain should be installed in the discharge pipe before the after cooler. Be sure to connect the after cooler outlet to the separator inlet when connecting the after cooler and the moisture separator together. If they are not connected properly, it will result in either poor aftercooling or poor separation.
The main header pipe in the system should be sloped downward in the direction of the compressed air flow. A general rule of thumb is 1” per 10 feet of pipe. The reason for the slope is to direct the condensation to a low point in the compressed air piping system where it can be collected and removed.
Make sure that the piping following the after cooler slopes downward into the bottom connection of the air receiver. This helps with the condensate drainage, as well as if the water-cooled after cooler develops a water leak internally, it would drain toward the receiver and not the compressor.
Another method of controlling the condensation is to take all branch connections from the top of the airline. This eliminates condensation from entering the branch connection and allows the condensation continue to the low points in the system.
Pressure DropPressure drop in a compressed air system is a critical factor. Pressure drop is caused by friction of the compressed air flowing against the inside of the pipe and through valves, tees, elbows and other components that make up a complete compressed air piping system. Pressure drop can be affected by pipe size, type of pipes used, the number and type of valves, couplings, and bends in the system. Each header or main should be furnished with outlets as close as possible to the point of application. This avoids significant pressure drops through the hose and allows shorter hose lengths to be used. To avoid carryover of condensed moisture to tools, outlets should be taken from the top of the pipeline. Larger pipe sizes, shorter pipe and hose lengths, smooth wall pipe, long radius swept tees, and long radius elbows all help reduce pressure drop within a compressed air piping system.
In recent years we have developed piping systems especially for compressed air. These compressed air piping systems typically have smooth walls, are lightweight, and reduce the installation costs associated with copper and stainless steel piping system.
