Compressed Air: A Quick Guide

Since 1993, Air Energy has been supplying our clients with a premium range of specialised compressed air equipment, and aluminium, HDPE or stainless-steel pipes Australia wide. Despite its ubiquity as an energy source in domestic and industrial settings, most people know little about compressed air; how it works, its practical applications, and how it compares to other energy sources for cost and efficiency. This quick guide is intended to answer some of those questions and give you a basic understanding of compressed air.

What is Compressed Air and How Does it Work?

Compressed air is created when air is forced into a pressure vessel using an electrically or diesel powered air compressor and is stored at a pressure greater than atmospheric pressure. The compressed air is then stored until it is needed and is released as pneumatic energy.

What are the Practical Applications of Compressed Air?

When released at the point of use, compressed air is converted into pneumatic energy that can be used as a power source for any number of mechanisms. Spray painting and various forms of sand blasting use compressed air, and pneumatic energy is an especially popular choice in automated industrial processes, where it can be used to move items through multiple production processes. It is well suited to mechanisms that perform repetitive actions at great force, such as industrial drills and jackhammers and pneumatic tools are much lighter than electric ones, saving OH&S issues and operator fatigue. Pneumatic energy is also used in car and truck braking systems.

What Are the Benefits of Compressed Air?

One of the main benefits of using compressed air is that, unlike other energy sources such as oil, air itself cannot be depleted, as a limitless amount exists in our atmosphere.

The machinery used in pneumatic systems is also highly durable when compared with other systems. The absence of corrosive elements such as oil paired with the smooth, low impact movements characteristic of pneumatic systems means they are not subject to the same wear and tear. This means lower maintenance costs and remarkable longevity.

Finally, pressurised air can be released back into the atmosphere with no negative consequences. The benefits here are two-fold: firstly, this makes compressed air one of the most environmentally friendly sources of energy; and secondly, it avoids the exorbitant costs involved in the processing and disposal of waste matter associated with other energy sources.

How Efficient/Expensive is Compressed Air?

As explained in the previous section, compressed air has a number of advantages over other energy sources when it comes to cost, but this doesn’t mean that it will be the cheapest option for every situation. Electricity is required to power the machinery that produces compressed air; the greater the pressure and the volume of air required, the more electricity will be needed, and therefore the greater the cost.

However, many processes do not require air to be compressed to the maximum pressure the compressor is capable of producing. Knowing the appropriate volume and pressure required for a given task can greatly reduce the costs of running a compressed air system.

Do Compressed Air Systems Leak?

Even a small hole in the compressed air system can lead to leakage, and those leaks can result in significant losses. Finding and repairing the source of a leak can be time-consuming but very cost effective, and it is for this reason that we suggest a proactive approach to avoiding leakage rather than a reactive one. Investing in high quality system components and using the advice of specialists when creating and maintaining your compressed air system is the best way to avoid unnecessary costs associated with leakage.

Compressed air systems have a number of advantages over electrical, hydraulic, and other kinds of systems commonly used in manufacturing industries. 240 volt electric powered tools and equipment are a well-documented and known OH&S issue, as well as being heavier due to the inherent design of electric motors powers them. Hydraulic power, no matter how well made regularly is associated with messy oil leaks and the hoses are stiff and cumbersome compared to compressed air hoses. Battery powered tools although much improved on earlier models lack the power available with pneumatics and need constant recharging of the limited lifespan of the batteries.

Air Energy supplies complete compressed air systems along with proven high-quality parts including polymer, aluminium, or stainless-steel pipes Australia-wide. In order to bring our customers, the best possible products and give advice they can count on, we draw on our years of experience designing and delivering compressed air systems to the broadest range of diverse industries. In this blog, we use that same experience to offer you some of our top tips for an optimal compressed air system

1. Use the Correct Size of Feeder Pipe

The feeder pipe as the name implies connects the compressor equipment to the ring main and is the main artery of all the compressed air used in your system. If the feeder pipe is too narrow, the airflow will be restricted, resulting in pressure drop and a less efficient overall system. You should always use a feeder pipe that is one size larger than the ring main to avoid airflow restriction

2. Minimise Elbows

You should design your compressed air system to feature as many straight lengths of pipe as possible and keep the number of elbows to the bare minimum, as each elbow results in a pressure drop equivalent to an additional 1-3 metres of straight pipe. Wherever possible, use radius bends and generally endeavour to make your system as straight as it can be. Balancing that is the requirement to allow for pipe expansion and contraction. As a rule-of-thumb 30 metres is regarded as the maximum straight length between expansion/contraction points.

3. Reduce and Manage Contamination

While compressed air systems are clean and dry compared to other types of systems, they can still become contaminated, which leads to corrosion, decreased efficiency, and the need for frequent maintenance and repair. The first step to avoid this problem is ensuring there is minimal contamination in the air supply. As compressed air is typically 8 bar, that means 8 x the contaminants in the surrounding air is concentrated in each volume of compressed air. Choose a location for your system that is as free of moisture and other pollutants as possible and install an air filtration system.

4. Monitor and Address Leakage

There’s a reason we use the term “airtight” to describe something that is totally secure and without fault; compressed air doesn’t require a lot of room to escape, and even a tiny leak can lead to a massively underperforming system. It’s important to locate and fix leaks as quickly as possible, although unfortunately, there are often no external signs of such damage; a leak generally needs to be significantly advanced before you are able to hear it. The best way to avoid this is to start with high-quality pipes and fittings installed by experienced and reputable technicians.

5. Use High-Quality Pipes and Fittings

Leading on from our previous point, using the best quality materials will reduce the likelihood of faults and increase efficiency from the get-go. Conduct thorough research before choosing a supplier/technician and spend plenty of time talking to them to make sure they understand the requirements of your system. They should be able to explain in simple terms why a particular material or product is the best choice for your application.

6. Plan for Expansion

When you are designing your compressed air system, take the time to think about whether it will likely need to be expanded at some point in the future. If you do eventually need to expand, it will be much easier, faster, and more affordable if this possibility was incorporated into your initial design.

As we move towards the phasing out of fossil fuels in favor of renewable energy sources, the next decade is set to be an exciting and challenging time for us and the HVAC industry as a whole.

The most significant and pressing goal currently in place is the stated aim of the European Parliament to bring about a 55% reduction in carbon emissions by 2030, with the end goal of reaching 0 carbon emissions by 2050. In order to make this happen, we need to explore all the renewable energy sources at our disposal. One of the most promising options currently on the table is thermal solar power. In this blog, we look at how thermal solar power works, its benefits for the HVAC industry, and why steel pressfittings offer the best system to facilitate the transition.

Solar Thermal Power Today

Solar power has long been considered one of the most efficient, cost-effective, and truly green alternative energy sources. The modern solar panel was invented in 1958, and over the following decades, solar power technology spread around the world. Today, it is commonly used for many industrial and residential applications.

Over the last two decades, the technology used to generate and distribute solar power has made huge strides, and the cost of solar panels has dropped significantly while their efficiency has improved and the list of applications to which they are suited has grown. Thermal solar power was previously limited to heating a household’s water supply, but today it used to fulfil many different functions. Through the use of specialised chemicals and inverter cooling technology, solar thermal power can now be effectively used to cool as well as heat buildings.

With the sun providing a virtually limitless supply of energy, thermal solar power will be able to augment and then entirely usurp traditional energy sources between now and 2030.

Why Steel Pressfittings?

The pipes in thermal solar energy systems are required to transport fluids at extremely high temperatures, making them subject to constant thermal expansion. This makes them unsuitable for use with copper pipes, which will deteriorate quickly. Stainless steel is much better suited to withstand thermal expansion and is generally more durable than copper and other materials. Properly maintained, a stainless steel system can last many decades with no serious malfunction.

Pressfitting systems are fast and easy to assemble, and unlike other types of systems that require welding, they do not use an open flame. This is especially beneficial for solar thermal power systems, which often carry highly flammable fluids. Our Eurotubi pressfittings are available in a wide variety of sizes and with differing thread and nut configurations. The right component will also depend on the maximum temperature of the system and whether there is steam present.

At Air Energy, we are committed to bringing our customers the latest, most innovative range of pipes and fittings for HVAC and compressed air systems available anywhere in the HVAC industry. As governments and industries around the world move towards more renewable models, we endeavor to stay on top of advancing technology as it happens. The two main goal posts set by the European Parliament for the prevention of global warming are 2030 and 2050. By 2030, they aim to reduce carbon emissions by 55%; by 2050, they aim to use no fossil fuels whatsoever. We think this is not just admirable, but, with the right combination of ingenuity and commitment, actually achievable,

A big part of staying ahead of the curve is being able to envision what the next stage of development might look like. Traditionally, a huge amount of global energy use has been consumed by HVAC systems. With the world population growing rapidly and ever greater demands being placed on the energy supplies of our towns and cities, engineers and planners have been looking at how they can continue to provide heating, ventilation, and cooling while reducing their carbon footprint. 

HVAC Systems in Smart Cities

“Smart City” is a term used to describe urban areas where there is a high level of interconnectedness between infrastructure, transport, energy supply, and other elements of the urban environment. Part of the idea is to increase energy efficiency with the primary goal of greatly improved environmental sustainability. In the Smart City, for example, if one building is experiencing excess heat, the underlying smart system would be able to harness that heat energy and transfer it to another building.

In order for this to happen, all systems would need to be interconnected at the data level and would use highly sophisticated fiber optics technology and Smart Metres in place of the flow metres and pressure gauges that are currently standard for these systems. Currently, pressure gauges need to be placed at various points throughout the HVAC system to accurately monitor the status of the various processes and equipment. Fiber optic cables allow large amounts of complex data to be transmitted at high speeds, meaning they would be capable of communicating information about the temperature, pressure, and any faults in the systems to the mainframe.

How Press-Fitting Pipes Fit in

The unique Europress press-fitting system is already making HVAC systems more efficient and sustainable, and that same technology will serve to optimise the systems in Smart Cities. Built from high quality steel, Europress pipe fittings are fast and easy to install, and are particularly well suited to use with sophisticated measuring equipment. 

The unique O-ring coloured sleeve system employed by Europress makes it easy to identify potential leaks during the installation process. When the fittings are properly attached, the coloured, plastic sleeve on the end of the pipe fitting falls away. This means technicians can spot any faulty joins before the system is turned on.

In our previous blog, we discussed how to choose the right material for your industrial piping system. We took a look at the main varieties of material used in industrial piping, describing the benefits and limitations of each and touching on their most suitable applications. This month, we’re throwing a spotlight on stainless steel. We’ll discuss the advantages of stainless steel as a material and look at some of the component parts of stainless steel compressed air systems. In particular, we will focus on stainless steel press fittings and what it is that makes these so popular for use in compressed air systems.

What Makes Stainless Steel So Special?

Stainless Steel is an umbrella term applied to corrosion-resistant steel alloys containing 10.5% or more chromium. Their high resistance to corrosion is due to a thin but highly protective layer of chromium-rich oxide film that coats the outer surface. What is remarkable about this layer of oxide is that, in the presence of oxygen, it is actually self-repairing. This means that minor damage caused by abrasion or cutting is quickly repaired. This same layer of oxide means that stainless steel is also highly resistant to rust.

Stainless Steel System Fittings

In addition to the pipes themselves, Air Energy offers an extensive range of innovative No Leak Solution press fittings. These fittings feature a thin, plastic film fitted to the outside of the o-ring. This plastic film tears and falls away only once the fitting has been securely pressed into place. This means that any faulty connections will be easily identified during the installation process.

The Benefits of Stainless Steel Press Fittings for Compressed Air Systems 

Stainless steel pipes can be much thinner than other materials, such as aluminum, while still being highly durable and reliable. When used as part of a press fitting system, they are also much easier and quicker to install, resulting in significant savings in time and labor. For these reasons, stainless steel systems tend to be much more affordable than aluminium piping systems to buy and install.


Besides the initial costs of your compressed air system, the long-term operation and maintenance costs will be one of your key considerations. The unique, rust- and corrosion-resistant properties of stainless steel mean that it is highly durable, although regularly scheduled maintenance is always recommended to catch small areas of degradation before they begin to affect functionality. 


Air Energy’s unique No-Leak Solution press fittings result in less of the compressed air leaking out of your piping system. This translates to a more efficient, less costly, more eco-friendly compressed air system. Not only do our press fittings prevent leakage of compressed air; the secure connections also mean that there is less opportunity for grease, moisture, and dust particles to enter the system, all of which can hasten wear-and-tear and lead to deterioration of the pipes.

Stainless steel piping utilizes an economical cross-section of steel to create a common and important product in manufacturing and construction industries. Industrial pipes are widely used in architectural applications and civil engineering projects ranging from sewage to oil and gas and compressed air systems. However, stainless steel piping is also used to make stair railings, window guards and contemporary furniture. Whatever your project, you will find stainless steel piping to be a strong and durable product.

The two common types of stainless steel used in industrial piping are 316 and 304, along with welded and seamless variations determined by the application, which production method is best adopted.

In this blog we will look at the difference between welded and seamless stainless-steel piping and how each product benefits their industry applications.

  1. Appearance

The most striking difference between a stainless-steel seamless pipe and a stainless-steel welded pipe is appearance.

Welded stainless steel is polished and mirror-like, while seamless stainless steel is matte and off-white. You may decide to choose one material over the other based on their appearance value.

  1. Seamless Stainless-Steel

The stainless-steel seamless pipe is a long strip of hollow steel that is free of joints. Thick seamless stainless-steel is economical and durable, with a wide range of applications, while thin seamless stainless steel comes with a higher price tag and usage limitations.

Stainless-steel seamless pipes are made through a process of cold rolling, cold drawing or hot extrusion, where there is no welding point on the tube. Generally, seamless stainless-steel has uneven wall thickness, low brightness, a high production cost around sizing, along with plenty of pits and black spots on the inside and outside that are hard to remove. However, where appearance is not important, seamless stainless-steel makes a superior product that is for high pressure and high strength applications.

  1. Welded Stainless-Steel

Welded steel pipes, also known as welded pipes or tubing, are longitudely welded after being rolled to a precise diameter in a continuous process.

Welded steel pipes have a straightforward production process, and come in many varieties and specifications, but as a material the strength is less than seamless steel. That said, the quality of welds is being continuously improved, and the variety and specifications of welded steel pipes are only increasing, making this steel material applicable in more and more industries, including high-pressure environments and sanitary tubing.

  1. Performance and Price

Seamless pipes perform better than welded pipes in terms of durability and pressure and high temperature resistance. The manufacturing process of welded piping is constantly improving, resulting in mechanical properties that in many cases match or approach the benefits of seamless pipes. However, for the time being, the more complicated production process still results in a more expensive pipe. For some applications, seamless pipes may also lack the appearance value of welded pipes. If you are having trouble deciding, consider the following factors:

(1) A welded tube is generally preferred as a decorative tube, product tube and sanitary tube, or wherever a project demands a good surface effect.

(2) For low pressure fluid transportation, you can also depend on the material characteristics of stainless-steel welded pipes.

(3) For large scale pipelines, as well as pipelines that require high temperature, high pressure, and high strength properties (such as important industries like oil refineries and nuclear power plant boilers) stainless steel seamless pipes are the obvious choice.

Stainless steel is a cost effective, low-maintenance metal used in civil and mechanical engineering projects Australia wide. Stainless steel is particularly popular for pipe fittings because it is resistant to oxidation and has no effect on other metals. Stainless steel has applications everywhere from shipping, oil and gas, water treatment facilities, energy industries, to the textile machinery.

Stainless steel is an umbrella term for a family of corrosion resistant alloy steels containing 10.5% or more chromium. Stainless steel has a chromium-rich oxide film on the surface, which makes it resistant to corrosive attack, and although stainless steel is relatively thin and lightweight, it is highly protective and strong, with a tensile strength ranging from about 621 MPa to 1300 MPa.

As a result, stainless steel is the material of choice for durable long-life span pipes and pipe fittings. There are five basic grades of stainless steel that you will frequently come across.

Grades and Basic Types

Stainless steel can include other elements besides chromium, such as nickel, molybdenum, titanium and niobium, giving rise to a wide range of different steel types and grades. The grade of stainless steel refers to its quality, durability and temperature resistance. The most common grades are 304 and 316, characterised by their different levels of corrosion resistance in saline and chloride exposed environments, as well as differing levels of heat tolerance. Stainless steel can be further divided into five basic categories:


18% chromium content and 8% nickel. Excellent corrosion resistance, excellent weldability, excellent in high and low temperatures, hardened by cold.


Varying chromium content between 12 and 18% and a low carbon content. Moderate to good corrosion resistance, hardened by heat. Poor weldability.


High chromium (18 to 28%), moderate nickel (between 4.5 and 8%) and in many cases molybdenum (2.5 to 4%). High resistance to stress and corrosion, increased resistance to chloride iron, high tensile and yield strength, good weldability.


Relatively high carbon of 0.1 to 1.2% and chromium of 12 to 18%. Moderate corrosion resistance can be hardened for high strength. Poor weldability.

Precipitation Hardening

Formulated so they can be supplied in a solution treated condition. Characterised by corrosion resistant properties, high strength and weldability.

Pipes and Fittings

Following the above, selecting stainless steel piping and fittings by grade and category is the next step. Pipes and fittings are chosen through the careful review of their purpose and environment, including any chemicals they may come into contact with.

Stainless Steel Tubing for Resistance to Corrosion

Austenitic and martensitic stainless steels are frequently employed when corrosion is the biggest hurdle. Austenitic steel, with its high quotient of chromium and nickel, is especially resilient.

Pressure Pipes

High pressure pipes require alloy-elements to resist stress and high temperatures. Piping made from solid chromium or chromium and nickel alloys is common, particularly in seamless, welded and electric fusion combinations.. Use of press fitting connections has revolutionised stainless steel installation, saving time, specialised labour, welding gas, hot work permits etc.

Hydraulic Line Tubing

Used for fuel lines and hydraulic systems, hydraulic line tubing is typically smaller in diameter than other tube types. Austenitic steel types are ideal for their strength and corrosion resistance.

Stainless Steel Sanitary Tubing

As the name suggests, sanitary tubing is designed to maintain sanitary standards. Depending on your requirements, sanitary tubing can be austenitic or ferritic, and is defined by being non-porous and easy to clean, suitable for pharmaceuticals, food and beverage, and drinking water applications.

Mechanical Tubing

Mechanical tubing is typically martensitic, composed of high carbon and chromium ratios that can be hardened for strength.

The role of pipe fittings to aid the system of transferring liquids and other products around a plant facility or system. Pipe Fittings connect bored of two or more pipes or tubes to other separate equipment.

What is the role of the Pipe Fitting?

Stainless steel Pipe fittings are the ideal choice for those in the industrial and commercial sectors who need a pipe fitting that will hold up to the job. Pipe fittings can also be used to seal or close any pipe.

Benefits of Stainless Steel Pipe Fittings

Stainless steel pipe fittings have replaced brass fittings and it is not hard to see why. Stainless steel has a high corrosion resistance not to mention that the steel possesses a self-repairing ability due to the formation of a passive oxide film. Stainless steel pipes offer long lasting resistance to oxidation and corrosion due to this. Furthermore, as stainless steel fittings are non-toxic, stain resistant, easy to clean and are long lasting, this makes them critical for the food and pharmaceutical industry. In addition to this the high corrosive resistance coupled with its ability to withstand high pressure makes it an ideal component in the building and construction industries.

Challenges of Stainless Steel Pipes

While the benefits of stainless steel make it an ideal material to work with, there are some disadvantages that are worth considering. Firstly, stainless steel hardens as you work with it. And secondly, stainless steel pipes and tubing need to remain sterile while the system is being constructed. Both of these issues make it harder for engineers to work with, as bending the pipes will cause it to harden, so accuracy is a must. Maintaining a sterile system means that any tools being used to cut or bend the pipe must be clean and safe so as to avoid any potential issues down the line. This is especially important if the piping is to be used for drinking water, as any contamination of the pipe can lead to health issues arising.

How to choose your Pipe Fitting

There is a variety of different pipe fittings which can make it to purchase the most suitable fitting for the job. Firstly, identifying the connection type, whether it be male or female threaded. Female threads are used on the inside of the pipe whereas male fittings have the thread on the outside.

Secondly, pipe fittings can be designed with sleeves that are slip-fit. This means that the pipes slip together to form a secure connection.

While there are many different materials that pipe fittings are made from, many recommend using a fitting that is made from the same material that the pipe is made of. Other important considerations to consider are:

  • Fitting type
  • Size
  • Check for flow
  • Design
  • Standards and codes
  • Thickness

Types of Stainless Steel Fittings

Stainless steel tube fittings are all the connecting fittings that butt weld to tube. These fittings are measured on the outside diameter of the tube and are available in grades 304 or 316 stainless. The main forms are:

  • Tube bends in 45 degree, 90 degree, 180 degree and 1x Diameter short radius 90 degree
  • Tube concentric and eccentric reducers
  • Tube tees in equal, reducing, swept and 45 degree branches
  • Tube crosses
  • Tube Y pieces
  • Tube dome caps
  • Tube end discs
  • Tube hose tails
  • Tube sealing flanges

Stainless steel is light, strong and resistant to corrosion. It’s an ideal material for piping. But there are long-standing misconceptions about stainless steel that can lead to applications not having the most appropriate type.

Avoid costly and time-consuming repairs. Familiarise yourself with this material by separating fact from fiction. Improve your use and maintenance of stainless steel and learn how to choose which type is appropriate for specific applications.

  1. Stainless steel will never rust.

FICTION – Anyone familiar with metals will tell you that stainless steel is still subject to rust. Made with iron, carbon, nickel, molybdenum and chromium, it is the last element that makes it particularly corrosion-resistant. But improper maintenance renders this protective element less effective.

When cleaning your stainless steel pipes, avoid using solutions that contain chlorine. These cleaners can pit the surface of the stainless steel and create deep pit holes in the metal. Prolong your pipes’ lifespan by using cleaners that are specifically for stainless steel. Additionally, use a soft bristle brush instead of steel wool to avoid damaging the damaging the surface. Steel wool leaves microscopic particles in the surface, that then rust making the stainless steel appear as if it is corroding. If the chromium oxide surface on stainless steel is scratched, the exposed chromium quickly oxidises forming a tightly bonded chromium oxide passive skin that resists further damage.

  1. Stainless steel is more affordable than other piping materials.

Fact – Although stainless steel is more expensive than other materials, it is more cost-effective in the long term. Its durability, tensile strength, and corrosion resistance make it easier to save on repairs and replacements. With the proper maintenance, you can use the same stainless steel pipes for decades.

  1. Stainless steel is a recyclable material.

FACT – Stainless steel is one of the most recycled materials around the world. Additionally, it doesn’t suffer from degradation even after multiple rounds of recycling. Now, you don’t have to add broken pipes in the landfill. Redirect them towards recycling plants to give them new purpose and decrease your carbon footprint.

  1. All stainless steel is the same and can be used anywhere.

FICTION – There is a misconception that there is only one type of stainless steel when there are four main types with multiple variations. Knowing how to differentiate them will help you determine which type is appropriate for your application.

  • Austenitic steel is non-magnetic. Containing chromium, nickel and carbon. Its high nickel content gives it better resistance to stress corrosion cracking.
  • Ferritic steel is magnetic and is a nickel free grade with varying chromium levels from 12-18%, making it less expensive than others. But like austenitic steel, ferritic steel is resistant to stress corrosion cracking.
  • Martensitic steel has higher carbon levels than the others and is the first branch of plain chromium stainless steels. This makes it harder to weld, often requiring pre- and post-weld treatments. This is the steel type often used to make cutting tools.
  • Duplex steel is a combination of austenitic and ferritic. Most grades include some molybdenum plus some nitrogen addition. Its higher yield strength is also the reason behind its popularity in corrosive piping applications.
