Welded ERW Steel Pipes For Construction
ERW welded steel pipe is a steel pipe made by electric resistance welding after being formed by crimping a steel plate or a steel strip.
ERW stands for resistance welding, which has the characteristics of high production efficiency, low cost, material saving and easy automation. ERW welded pipe is one of the most common pipe materials.
Because of its durability and corrosion resistance, it is widely used in aviation, energy, automotive, and light industries. ERW welded pipes are also often used as structural pipes.
Resistance welding is one of the most important welding methods.
