Why Expansion Loops Are Essential for Your Compressed Air and Fluid Pipework Systems

When installing compressed air pipework in any industrial or commercial setting, ensuring the long-term integrity and efficiency of the system is essential. One key component in achieving this is the expansion loop—a vital yet often overlooked feature in piping design.

At Airquip, we believe in providing more than just high-quality products—we ensure your systems are installed and maintained to the highest standard. Expansion loops are one of the critical elements that we incorporate into every installation, and here’s why they are so important.

What is an expansion loop?

An expansion loop is a specially designed section of piping that allows the pipe to absorb and accommodate movement caused by temperature changes. This movement, known as thermal expansion and contraction, happens naturally when pipes heat up or cool down. Without a mechanism in place to handle this movement, pipes could become damaged, leading to leaks, bursts, or misaligned fittings.

An expansion loop consists of a series of 4 right-angled pipe connections that form a loop shape. These loops create a “bend” in the pipework that provides enough flexibility for the pipe to move without putting undue stress on the rest of the system. They work by allowing the pipe to expand or contract within a controlled space, absorbing the changes in length as the temperature fluctuates, whether from seasonal temperature shifts or from the hot or cold nature of the fluid or gas inside the pipes.

What Does an Expansion Loop Do?

The primary job of an expansion loop is to prevent damage caused by thermal expansion and contraction. When a fluid, like compressed air or any other media, travels through a pipe, its temperature can rise and fall, making the pipe expand and contract. Over time, these constant shifts in size could result in:

• Pipe stress: Leading to bends, cracks, or even bursts.
• Joint or fitting failure: If the pipe shifts and strains the connections.
• Leaks: Pressure could build up at weakened points, causing leaks that are costly to repair.

An expansion loop helps to avoid these issues by providing the pipe with the necessary room to move. It acts like a shock absorber, reducing strain on the system, ensuring that everything from the pipe to the fittings and valves remains intact.

How Does an Expansion Loop Look?

Visually, an expansion loop is a simple yet effective feature that stands out in a piping layout. The loop is made up of a series of right-angled connections arranged in a compact, typically rectangular or square shape, which looks somewhat like a “kink” in the pipe. These loops are strategically placed at set intervals along long stretches of pipe to ensure that every part of the system has the room it needs to expand and contract safely.

You’ll typically find these loops in areas where straight pipe runs extend over longer distances, especially where there are temperature fluctuations. The loops will be placed based on the material of the pipe, its diameter, and the nature of the fluid being transported.

Why Are Expansion Loops So Important?

Preventing Pipe Damage

Pipework is designed to withstand the pressures and forces associated with moving fluids or gases. However, constant temperature fluctuations can lead to movement within the pipe that, without an expansion loop, may cause damage. An expansion loop allows the system to adjust to these fluctuations without causing cracks, misalignments, or breakages in the pipework.

Protecting Your Investment

Installing an expansion loop might seem like an added step, but it’s actually a proactive approach that can save you from costly repairs down the line. Pipes that aren’t equipped to handle thermal expansion can fail prematurely, leading to downtime, repair costs, and system inefficiencies. By incorporating expansion loops from the outset, you ensure your pipework system performs reliably for years to come.

Maintaining System Integrity

Whether you’re running a high-performance compressed air system, transferring fluids, or working with any type of pipeline installation, maintaining system integrity is essential. Expansion loops help preserve the structure of your entire system, ensuring that all components function as intended, without the added risk of mechanical damage caused by thermal stresses.

Reducing Downtime and Maintenance Costs

Systems without expansion loops are more likely to experience mechanical failures. A burst pipe or a faulty fitting due to lack of movement allowance can lead to costly downtime. Installing expansion loops reduces the likelihood of such failures, minimising the need for costly repairs and maximising system uptime.
