The right compressed air piping ensures your compressed air system can operate efficiently. To ensure your piping is suitable for your application, we can help.
In this article, we explain which types of air piping are best for compressed air systems, covering materials and the best compressed air piping available in New Zealand.
The quality of your compressed air and the running costs of your system are influenced by the type of material used for your piping. Some materials can be corroded by lubricants used in the compression process, leading to leaks and particulates in the airflow.
Additionally, some materials can add unnecessary friction and cause the air pressure to drop in the pipes, causing inefficiencies and leading to costly repair callouts. Therefore, we recommend a non-corrodible, low-friction material like steel or aluminium.
Stainless steel is an alloy of chromium and steel. The chromium content provides enhanced corrosion resistance because it oxidises quickly and produces a stable, passive oxide film on the exposed surfaces.
PE piping is another common choice for low-pressure compressed air systems due to its low cost. However, PE pipes do not last well over time and tend to sag between connections. These bends become moisture traps and allow the compressed air to pick up water as it passes through. Even with a refrigerated dryer, this will result in some moisture reaching your end-use.
PVC stands for Polyvinyl Chloride and it is inexpensive, easily accessed, and easy to install. However, PVC piping is plastic so it can be prone to cracking. Therefore, PVC pipes are not durable enough to withstand high pressures over a long period as they will become brittle, break, and even shatter.
Because of these safety risks, many countries have already banned the use of PVC piping for compressed air systems. Fortunately, there are safer and more durable options on the market that can be used for compressed air systems, such as aluminium. If you are currently using a PVC compressed air system, we recommend looking to replace it as soon as possible.
Aluminium is known for its reliability and durability. It won’t degrade or corrode, it’s flexible, and it’s incredibly lightweight, making it an ideal choice for compressed air piping. Additionally, most aluminium pipe is supplied ready to use so it doesn’t require much preparation, apart from cutting to size.
Here at Industrial Air Systems, we recommend opting for aluminium in your compressed air piping system. Not only is it long-lasting and corrosion-resistant, but it also provides a high level of air purity for your application.
Alu Air piping is manufactured from aluminium to provide durability and corrosion resistance in your compressed air system. The Alu Air system ensures superior compressed air reticulation, resulting in a high-performance, long-lasting, and reliable solution.
The smaller of these three options, this loop piping system is suitable for smaller plants with 6m to 8m stud height, based on the height of the ring main. With four droppers, this system is great for smaller applications. Key characteristics include:
This loop piping system is suitable for medium plants with 8m to 10m stud height, depending on the height of the ring main. With eight droppers, this system can supply multiple operational demands with even pressure. Key characteristics include:
This looping pipe system is suitable for large buildings with 8m to 10m stud height, depending on how high the ring main is placed on the wall. With twelve different droppers, this system is ideal for serving numerous operational needs whilst maintaining steady pressure throughout. Key characteristics include:
