Compressed Air Pipe and Fittings

Compressed air piping systems, used in a variety of industrial applications, are ideal for meeting specific energy requirements and delivering uncontaminated compressed air functionally and aesthetically.

Once compressed air has been filtered to remove contaminants and dried to reduce the presence of any damaging effects of moisture, it is conveyed through a compressed air pipe system to serve its unique purpose as an energy provider for industrial processes.

At Air Energy, we supply premium compressed air pipe and fittings for industrial and commercial applications across Australia. Whether you need lightweight PE100 poly pipe, corrosion-resistant aluminium pipe, or stainless steel press-fit systems, we can design a solution that suits your pressure, flow, and future expansion requirements.

Our range includes high-quality compression pipe fittings, socket fusion fittings, electrofusion fittings, and stainless steel press fittings from globally trusted brands.

Why Choosing the Right Compressed Air Pipe Matters

Compressed air is often one of the most expensive utilities in a factory.

While many people focus on the purchase price of the compressor, the real cost is in running the system.

Typical Lifetime Cost of Compressed Air

•    21% Equipment purchase
•    7% Service and maintenance
•    72% Energy consumption

Even a small pressure drop or air leak can significantly increase electricity costs.

The right compressed air pipe and fittings help you:

•    Minimise leaks
•    Reduce pressure drop
•    Deliver cleaner air
•    Lower compressor workload
•    Reduce energy costs
•    Simplify future modifications

Compression Pipe Fittings Explained

Compression pipe fittings are mechanical connectors that create a tight seal without welding.

They are commonly used with compressed air systems and offer several advantages:

• Quick and simple installation
• No hot work permits required
• Easy disassembly and reuse
• Excellent vibration resistance
• Leak-free performance

For many facilities, compression fittings provide the fastest and most flexible installation method.

How to Choose the Right Pipe Size

Correct sizing is critical for system efficiency.

When selecting compressed air pipe and fittings, consider:

1. Required airflow (CFM or L/s)
2. Pipe length
3. Maximum allowable pressure drop
4. Minimum operating pressure at point of use
5. Future expansion plans

An undersized pipe forces the compressor to work harder, increasing electricity costs.

As a rule of thumb, every 1 bar of unnecessary pressure increase can significantly increase energy consumption.

Selecting the Right Compressed Air Piping Systems for You

When putting together the compressed air pipe system that best meets your industrial requirements, follow these crucial steps:

• Select the right pipe size – Take the factors of required flow, distance and future expansion into account when choosing the best size (between 20 and 160mm). Other than these factors, knowing the minimum operating pressure of your equipment is critical to choosing the right pipe size. This should be based on the manufacturer’s minimum requirements, not what you have been previously operating at.
• Don’t Choose an Undersized Pipe – Using an undersized pipe restricts airflow, and some operator's effort to solve that is to increase air pressure. If you need to operate your system at 125 PSI to get to point-of-use 100 PSI, this produces 25 PSI of overpressurisation – resulting in 12.5 percent of wasted energy.
• Select fittings – there are different fittings available that best suit specific requirements. We stock Socket Fusion Weld fittings, Compression O Ring fittings and Electro Fusion Weld fittings.
• Select outlet requirements – choose outlet filtration, regulation and lubrication requirements, as well as quick couplings, hoses and other essential pieces that best serve your requirements.

If you need assistance in choosing the right fittings and outlet requirements, give us a call. Our air pipe specialists are knowledgeable on what types of outlet requirements and fittings complement our range of compressed air piping systems.

Frequently Asked Questions

What are compressed air pipe and fittings used for?

They distribute compressed air from the compressor to machinery, tools, and production equipment throughout your facility.

What are compression pipe fittings?

Compression pipe fittings are mechanical connectors that seal the pipe using an O-ring and tightening mechanism, eliminating the need for welding.

Which pipe material is best for compressed air?

The best material depends on your application:

• PE100 poly for flexibility and underground use
• Aluminium for clean, low-pressure-drop systems
• Stainless steel for demanding industrial environments

Can compressed air pipe be installed underground?

Yes. MaXair PE100 compressed air pipe is suitable for underground installations.

How do I reduce pressure drop in my compressed air system?

Use correctly sized pipe, minimise restrictions, and choose smooth-bore materials such as PE100 or aluminium.

How long do compressed air piping systems last?

With proper installation, many systems provide decades of reliable service. MaXair PE100 systems are backed by a 50-year warranty.

Are compression pipe fittings leak-proof?

Yes. When installed correctly, compression pipe fittings provide secure, leak-free connections.

Can you help design a complete compressed air system?

Absolutely. Air Energy provides design, supply and provide ongoing support for compressed air systems across Australia.

While planning a compressed air system, what material would be ideal?

Stainless steel Pipes - Stainless steel is widely used for its durability and corrosion resistance. There is a choice of 316L or 304 stainless steel. 304 is the most common choice due its lower cost, but 316L is preferred if there is a corrosive atmosphere. Press fittings make for a fast, leak free joint with no naked flames, as in welding. Stainless steel is harder and therefore slower to cut than aluminium or PE pipe.

Aluminium Pipes - Aluminium piping are one of the best materials for compressor air line pipe since they are lightweight, easy to install and leak-proof. They are also corrosion-resistant and inexpensive, making them ideal for installation.

Plastic Pipes - Plastic pipes are used very frequently too. They are lightweight, non-corrosive and easy to install. However care must be taken to support the pipe according to the recommendations to maintain straightness of the installation.

Black Iron - Black iron pipes have been used in installations for a long time since they are durable and robust. However, a significant drawback can be corrosion and rust. Additionally, iron can be challenging to cut and join now and then.

Copper Pipes - Copper pipes are an option often chosen by plumbers due to their familiarity with copper, but it is one of the most expensive choices. It is easily damaged and can develop brown or green corrosion. Correct sizing is often overlooked when not installed by someone inexperienced in compressed air pipework design principles.

Galvanised Steel Pipes - Galvanised steel pipes are similar to iron pipes except for corrosion resistance. This makes them preferable to iron. The heavy weight and difficulty in threading and leakproof sealing is a major headache apart from the likelihood of internal corrosion that over time restricts airflow and creates damage to equipment seals and pneumatics.
