Whenever someone wants ERW tubes, they come to us. Customers know that our business has specialised in these products for more than a decade. When they need our assistance, they’re confident that we can supply them with everything they’re looking for. Should you need us to, we can do the same for you.
When we say mechanical tubing, we’re referring to tubes created using the electric resistance welding procedure. There are multiple forms to consider for your project. To fashion them, we must use distinct processes. So that you can familiarise yourself with these operations, we’re going to discuss them here.
First, we have hot-rolled ERW tubes. Here, we roll the material, generally steel, into a tube whilst exposing it to high temperatures. This procedure generates tubing that’s easier to form. When compared to cold-rolling, it’s not as strong or as uniform in dimension. On the other hand, it is the most cost effective option.
Rolling is also essential here, just like with the hot process. The main variation however is that the cold process uses room temperature. Compared to hot-rolled ERW, the products here are stronger. This is because of the enhancements within the crystal lattice structure. There’s also a better orientation, shape, and grain size. Due to these attributes, the final tube has tighter and more consistent dimensions. In addition, there is a more uniform and much smoother surface finish. The product is also straighter.
For both types of tube, you don’t add filler during the welding. As a result, the weld’s composition remains identical to that of the parent material.
At Union Steel Tubes, we can supply you with any length of tubing you require. Thanks to our steel cutting and processing services, we can offer you steel ERW tubes in cut and random lengths. In addition, we have plenty of products in stock for a quick delivery.
