Tubes have many uses in numerous different sectors. They tend to transport gas, oil, and water. While they come in different forms, shapes, and sizes, they are typically made from steel due to its useful characteristics. Whatever the use, you want your tubing to perform as well as it can. For this reason you should opt for a pre-galvanised ERW tube.
What is galvanising?
Steel rusts from exposure to atmospheric conditions as time goes on if there is no form of protection. The extent of the rust will depend on the environment the metal is in.
Galvanising is a process in which manufacturers make steel more resistant to corrosion. This involves forming tubes using strips of heavy duty zinc coated steel. High frequency welding joins the edges together. By arc-spraying the external weld zone, you can enjoy a completely galvanised tube. There are a number of benefits this brings your final product.
When you compare it to other methods that offer protection, galvanising is an incredibly affordable option. For instance, a labour-intensive coating like painting will likely have higher costs. What you also have to consider is that when you galvanise your tubes, this will last a very long time in comparison to other coatings. Furthermore, it will not require a great deal of upkeep. This helps to minimise the maintenance costs for your ERW tube.
Tubes exposed to demanding conditions and elements can begin to degrade. However, with pre-galvanised products, you won’t have to worry. The tube will have protection from corrosion and scratching. This can last for 50+ years in most conditions. The zinc is a coating that will be permanently bonded to the metal which allows for stress free installation and transportation of tubes.
In fact, you will be able to make the most of a phenomenon known as preferential corrosion. This is where the zinc coating will start to corrode and rust before the steel does. Consequently, the steel won’t need touching up.
When it comes to protective coatings, galvanisation is one of the best for the environment. It makes your tubes much more durable but produces very little waste. Furthermore, the process has a minimal impact on the environment.
Are you looking for pre-galvanised ERW tube?
Anyone who is looking to buy quality pre-galvanised ERW tube must take a great deal of care. Working with the tubing such as cutting, forming, or drilling, might remove part of this layer. As a result, these areas need an extra coating to protect against corrosion.
