ERW tube manufacturing process
The full form of ERW is Electric Resistance Welded. An ERW tube or pipe is constructed using a specific type of ERW welding process that involves both seam and spot welding. ERW tubes are made from a steel strip that passes through a series of contoured rollers, which force it into a circular, square, or rectangular shape. This process is very different from the manufacturing process of a seamless tube, where the tube is formed by extrusion or piercing, and no welding is needed.
Steel, being the most common material, makes it possible to transport different types of vapor and liquid, such as gas or oil, in the tube.
