General principles of compressed air piping arrangement

The general principles of compressed air piping  arrangement include the following:

 air compressor  location selection. The air compressor should be placed in a clean, cool and dry environment, with the air inlet away from the vapour outlet or other places that generate moisture. Keep a distance of at least 30cm between the air compressor and walls or obstacles so that air can circulate to ensure cooling. The air compressor should be kept level and as close as possible to the place where compressed air is used.

 Principles of pipework arrangement. All pipework should be angled towards the air compressor's storage tank  or a drainage branch should be installed at the end of each branch to remove moisture from the compressed air. In a long and narrow plant, the piping system can be formed into a loop to reduce pressure loss. It is recommended that another storage tank be installed at the opposite end of the air compressor to reduce pressure drop and starting frequency.

 piping installation requirements. Branch lines should be connected from the top of the main line to avoid condensate flow into the compressor unit. Drainage devices should be installed in the low-lying parts of the piping to prevent freezing accidents. The piping connected to the compressor should have as few bends and valves as possible to reduce pressure loss. It is prohibited to install check valves or non-return valves on the gas supply line between the compressor outlet and the storage tank.

 connections and slopes. Compressed air pipes are generally welded connections  and flanged  or threaded connections are used for connections with equipment and valves. The pipeline should have a certain slope in order to exclude sewage in the pipe. The top of the pipe of the underground pipe is buried at a depth of not less than 0.7m.

 safety and maintenance. Pressure vessels such as gas storage tanks must be equipped with safety accessories such as safety valves , pressure gauges  and discharge valves  and be inspected regularly.

 Consider other factors. Avoid piping that interferes with interior lighting, window opening and closing, and equipment operation and maintenance. In areas where horizontal piping crosses, delineate the elevation range according to the piping direction to achieve a layered arrangement.

The above principles help ensure the efficiency, safety and long-term performance of compressed air piping systems.
