When it comes to installing a new piping system, you may find yourself overwhelmed with the options for your application. How do you know which type is best?

Many of our customers come to us asking this very question and wondering where to start. To help you make a decision, we have put together some information on the different types of piping you can use in your compressed air system.

Traditional Methods of Piping

Iron Pipe

Iron pipe is one of the most commonly used and traditional methods of piping for compressed air systems. In fact, it’s been around for decades.

Available in raw black or galvanized form, iron pipe can be installed by any plumber, and fittings are readily available in your local hardware store, meaning it’s easily accessible.

However, iron pipe does have a few challenges. First and foremost, iron pipe (and other similar types) cannot be easily adapted. Most altercations in the piping system need to be subcontracted to a plumbing contractor rather than done in-house.

Additionally, there’s the issue of corrosion. Regardless of whether your system has drying equipment, water will still enter the pipe network at some point (either because you don’t have any equipment or because your existing equipment needs replacing or repairing). Once water touches the iron piping, it begins to corrode. This can cause pressure drop due to pipe obstructions and can also lead to debris in your compressed air system, which are not only harmful to your equipment, but also to system users as it may blow into their eyes.

Other Piping

If you’re looking for piping that causes less, if any debris, thereby enabling cleaner delivery from your compressed air piping system, you could use copper, stainless steel, or ABS plastic for your application. Please note that PVC should never be used in compressed air applications, per OSHA recommendations.

However, similar to iron piping, these materials are not very adaptable, easy to modify, or even to install. These systems require special tools, experience and, in some circumstances, a hot work permit to install and modify. Additionally, some materials, such as stainless steel, are costly to purchase.

So, is there a material that meets all of your needs?

A Material Above the Rest

In the past 10 to 15 years, modular aluminum compressed air piping systems have been showing up in the market. Using modular aluminum pipes in compressed air piping systems offers many benefits, including zero corrosion, leak resistance, lightweight handling and, in some instances, in-house installation.

When it comes to modular compressed systems, we’re big fans of the Teseo brand. Its unique design, which is square on the outside and round on the inside, makes it structurally sound — meaning absolutely no sagging along your pipe lines and less supports when mounting!

However, more importantly, Teseo is guaranteed against corrosion and easy to install and modify (unlike other aluminum piping systems). Assembly is simple and requires less tools and permits than other types of piping as well. Teseo systems do not require threading, brazing, or welding, which not only means reduced time in installation, but also no hot work permit! All you need to assemble the Teseo system is a fine tooth miter box saw, pipe reamer and an Allen wrench. This system does not require special drilling jigs (like round pipe systems do), nor does it need special wrenches for tightening fittings. Plus, the pipe is three times lighter than your average iron pipe, which makes installation a breeze.

But it’s not just about the installation… even modifications are easy with Teseo! The system allows outlet plates to be added anywhere along the pipe’s profile without needing to install tees or unions. This means you can install the piping header first and can put in your air drops or outlets later, whenever you need them. This process can even be done under pressure (A.K.A. hot tapping), which is ideal for companies relocating equipment over a prolonged period of time while still running production. Hot tapping also eliminates the downtown iron piping systems need before doing any type of system alteration. Plus, you can place your drop directly over your point of use without unnecessary pressure drop caused by excess elbows and tees, which would be required in any other type of piping system.

There are several other great reasons to use Teseo for your compressed air system.

For starters, Teseo’s specification sheets are user-friendly. They provide the inside diameter measurements, unlike all other aluminum systems, which give the outside diameter measurements. Since this is where the air actually flows, you can push more air through the same diameter of a traditional pipe! A large inside diameter will amount for lower pressure drops and more airflow as you expand the use of your system.

Secondly, Teseo is also the only system that is 100% Aluminum — there’s no plastic in the fittings or the pipe. The piping is also extra-guarded against leaks with double O-ring seals on every fitting.

Here’s the best news though: Teseo is a stock item in our warehouse here in Chicago! You know what this means for you: one day (or same day if required) shipping straight to you.

While there are other round pipe or blue pipe aluminum piping systems on the market, none have the benefits Teseo does. So if you are installing a new piping system system in your facility, consider this: in a manifold system, air drops and connections can be positioned over its use point, unlike a traditional pipe system. Plus, Teseo is guaranteed against corrosion, easy to install and modify, simple to assembly, and comes with user-friendly spec sheets!
