What is the oxygen barrier property of a 16mm PEX pipe?

Hey there! As a supplier of 16mm PEX pipes, I often get asked about the oxygen barrier property of these pipes. So, I thought I'd write this blog to break it down for you.

First off, let's talk about what PEX pipes are. PEX, or cross - linked polyethylene, is a type of plastic tubing that's widely used in plumbing and heating systems. Our 16mm PEX pipes are super popular because they're flexible, easy to install, and durable. But the oxygen barrier property is what really sets them apart in many applications.

What is the Oxygen Barrier Property?

The oxygen barrier property of a 16mm PEX pipe refers to its ability to prevent oxygen from diffusing through the pipe walls into the fluid (usually water or a water - glycol mixture) flowing inside. In a closed - loop heating or plumbing system, the presence of oxygen can cause some serious problems.

When oxygen gets into the system, it can lead to corrosion of metal components like radiators, boilers, and valves. Corrosion not only shortens the lifespan of these expensive parts but can also reduce the efficiency of the entire system. For example, if the radiator starts to corrode, it won't transfer heat as effectively, and you'll end up using more energy to maintain the desired temperature.

Our 16mm PEX pipes with an oxygen barrier are designed to keep oxygen out. They have a special layer or coating that acts as a shield, blocking the oxygen molecules from seeping through. This is crucial for systems where metal components are present and need to be protected.

How Does the Oxygen Barrier Work?

The oxygen barrier on our 16mm PEX pipes typically consists of a thin layer of EVOH (ethylene vinyl alcohol) or other similar materials. EVOH is a high - performance polymer that has excellent gas - barrier properties. It forms a tight molecular structure that makes it difficult for oxygen molecules to pass through.

When the pipe is manufactured, this EVOH layer is either co - extruded with the PEX material or applied as a coating. The result is a pipe that offers a high level of oxygen protection. The thickness and quality of the oxygen - barrier layer can vary, but our pipes are engineered to meet strict industry standards.

Why is it Important for Different Applications?

Heating Systems

In hydronic heating systems, where water is circulated through pipes to heat buildings, the oxygen barrier is a must - have. As I mentioned earlier, corrosion can damage the boiler, which is the heart of the heating system. With our 16mm PEX pipes with an oxygen barrier, you can ensure that your heating system runs smoothly for years to come.

Plumbing Systems

Even in plumbing systems, the oxygen barrier can be beneficial. If your plumbing system has metal pipes or fixtures downstream, preventing oxygen from entering the water can help prevent rust and corrosion. This is especially important in areas with hard water, where the combination of oxygen and minerals in the water can accelerate the corrosion process.

Comparing Our 16mm PEX Pipes with Others

There are many PEX pipes on the market, but not all of them have a good oxygen - barrier property. Some cheaper alternatives may have a thinner or less effective oxygen - barrier layer, which means they won't provide the same level of protection.

Our 16mm PEX pipes are made with high - quality materials and advanced manufacturing processes. We test our pipes rigorously to ensure that they meet or exceed industry standards for oxygen diffusion. So, when you choose our pipes, you're getting a reliable product that will protect your system.
