ERW pipe stands for resistance Welded pipe. ERW pipe is welded by resistance welding technology, through the edge of the pipe heated to a molten state of more than 1000°C, 2000A to 10000A current, and then apply pressure to weld the edge of the pipe. The general welding pressure is 5MPa to 15MPa.
The steel pipe manufactured by resistance welding technology has extremely high production efficiency and greatly reduces the cost loss. Therefore, it is widely used in various applications
