Choosing the Right Pipe Material for Your Air Compressor System

When it comes to setting up a reliable and efficient compressed air system, choosing the right pipe material is just as important as selecting the compressor itself. The pipework you install affects everything from system pressure and energy efficiency to maintenance requirements and future scalability.

At Southern Air Systems, we’ve worked with businesses across Hampshire and the South to design, install, and upgrade air systems using a wide range of pipe materials. Here’s a breakdown of the most commonly used options, and what you need to consider with each.

Aluminium Pipework

Aluminium is a popular modern choice and for good reason. It’s light, easy to install, and has excellent flow characteristics.

Pros:

• Lightweight and easy to handle

• Resistant to corrosion without any internal coating

• Smooth internal surface helps reduce pressure drop

• Ideal for clean, dry air environments

• Easy to modify or expand later

Considerations:

• Higher initial cost than plastic or copper

• Needs to be installed by trained fitters for best results

Stainless Steel Pipework

If your environment demands strength and hygiene, stainless steel is a solid choice. It’s built for high-pressure, high-purity applications.

Pros:

• Extremely durable and corrosion-resistant

• Withstands high pressures and temperatures

• Suitable for food-grade and medical settings

• Long service life with minimal maintenance

• Excellent resistance to moisture and oil

Considerations:

• Heavier and more expensive to install

• Requires welding or threaded fittings, which can take longer

Copper Pipework

Copper is tried and tested, and has been used for decades in compressed air systems, especially in commercial workshops.

Pros:

• Clean and reliable for oil-free applications

• Readily available and familiar to most installers

• Good resistance to internal corrosion

• Suitable for mid-sized systems

• Works well for relatively low-flow rates

Considerations:

• Higher material cost than plastic

• Labour-intensive installation with brazing or soldering

Plastic Pipework

Plastic pipework can be a cost-effective solution for certain setups, especially in smaller or temporary systems.

Pros:

• Lightweight and quick to install

• Non-corrosive and easy to cut to size

• Ideal for low-pressure systems or occasional use

• Suitable for indoor applications

• Lower cost material for small budgets

Considerations:

• Not suitable for high-pressure or outdoor environments

• Limited lifespan compared to metal options

• Can become brittle over time

What's Right for You?

Choosing the right compressed air piping material depends on your specific setup, such as your compressor size, air demand, environment, and budget. Whether you're running a workshop, a food production facility, or a manufacturing line, we’ll guide you to the best solution.

We’re happy to carry out a site survey and recommend the most suitable pipework for your needs. And because we also handle the installation, you’ll get a clean, efficient system that performs from day one.
