The primary use for copper tubes is water heater components. However, the trouble is that they can oxidise in moist or damp conditions. If you find a green layer on your tubes, this is likely where it has had a lengthy exposure to humid conditions or water. This leads to the oxidation of the material. It is a variant of corrosion and, in extreme cases, it can harm your utensils. Should you fail to thoroughly examine this, you can experience tube failure.

The reason for copper turning green

Tube expansionHeating systems make use of copper over other substances. This is because it is a metal capable of conducting heat extremely well. You can circulate hot water through the tubes. The metal shall then absorb the heat from your water and radiate it into the air. After the copper has absorbed the water’s heat, it will remain hot for a lengthy period. It becomes an effective heating mechanism and keeps your water hot when it circulates through the house’s tubing.

The green colour that manifests on the tube is a type of oxidation you can liken to rust on steel. It forms under similar circumstances when you use unprotected steel. So, you can expect it if you expose the copper to air, water, and ambient temperatures. Like with rust, copper oxidation is corrosive. If you don’t attend to it, your tubes can corrode to the point where they will fail.

One spot where you will normally see this form of discolouration is where your tube goes through a mortar and brick or concrete wall. Any moisture or dampness existing in your walls can lead to the tubing oxidising and becoming green. Speak to us if you need first class tube expansion services.

Do I need to replace those green tubes?

The green oxide that is capable of manifesting on the tubes isn’t actually harmful. Its acidic appearance is deceptive in that way. It is actually an inert and non-toxic substance. Saying this, it does point to a potential problem for your tube that demands attention.

It is not necessarily mandatory to replace green heating tubes. If you do see oxidation on them though, you need to investigate and locate the source. There might be a pinhole leak in your tube. Alternatively, there can be dampness in a wall or a faulty join. Should you choose to leave the oxidised tube be, the leak can get worse. The tube may burst. This corrosion can also weaken your utensil to the point where it bursts.

Whatever your situation, if green oxidation shows up on your heating tubes it is probably not an emergency. In fact, it can take quite a while for it to start happening. You should do some investigating to find the cause though. If there is a leak or pooling water, you need to take action.
