Air compressor piping system
An air compressor piping system is a network of pipes and components that deliver compressed air from the compressor to the end-use equipment or tool.
The inlet and discharge outlet should be designed in such a way that they allow for a smooth flow of air over the entire piping diagram.
The air compressor piping diagrams are designed to provide efficient and safe transportation of compressed air while minimizing pressure drops and energy loss.
When designing your piping system, the following tips will help you minimize the chances of poorly pressurized air.
The compressor is the heart of the system, where the air is compressed and sent through the compressed air piping system.
The piping connects the compressor to the end-use equipment. It can be made of various materials, such as black iron, copper, aluminum, or plastic pipes, depending on the specific needs of the piping system.
The bypass pipe should also have a valve on it to cut the air supply when the maintenance is completed.

Temperature tolerance: You need to be sure that the pipe material you select can withstand the temperature of the compressed air as it circulates through the air system. To find out what temperature rating your system needs, consult the manufacturer’s instructions.
Cost: Another crucial factor is the pipe material’s cost. Certain materials, like aluminum or plastic, can be more expensive than others, like copper and stainless steel.
It is always important to consult an expert to avoid unnecessary pressure drop or extra costs.
Maintenance: Certain materials need more upkeep than others. For instance, the black iron pipe may need to be cleaned and painted regularly because it is susceptible to rust.
In general, black iron, copper, aluminum, and plastic are compressed air pipes materials most frequently utilized in air compressor systems. While selecting the ideal material for your air system, it’s crucial to carefully weigh the criteria mentioned above because every material has unique benefits and drawbacks.
What is the proper piping for an air compressor?
Depending on the particular needs of your compressor and your application, the correct piping for a compressed air system will vary. Here are some general principles, though:
Use the right size piping: The compressor’s flow rate should be taken into account while determining the piping size. To prevent pressure drops and excessive back pressure, use piping that is at least as big as the compressor outlet.
Use smooth pipes: The air pressure drop and turbulence in the airflow will be reduced by smooth pipes.
Use pipe fittings: Employ the right pipe fittings to connect the piping material and ensure a tight seal. The use of tapered pipe threads should be avoided because they might lead to leaks and turbulence.
Install filters: Add filters to remove dirt and moisture from the compressed air before it enters the piping systems. Moreover, consider installing an extra receiver at the end of the line to take care of peak air demands.
Avoid excessive bends: Prevent excessive twists and turns in the pipe, since they can generate turbulence and pressure drops.
Use the right material: The compressed air and the environment in which it will be used should both be compatible with the material used for the piping systems. Copper, steel, and aluminum are typical building materials.
Install regulators: To regulate the compressed air’s pressure as it enters the pipe system, install regulators.
Remember to examine your compressor manufacturer’s guidelines and specs for more specific requirements and tips for your particular compressor.
How to calculate pipe size for an air compressor?
