ERW Pipe
ERW Pipe Description
ERW steel pipes are manufactured by low-frequency or high-frequency resistance “resistance”. They are round pipes welded from steel plates with longitudinal welds. It is used to transport oil, natural gas and other vapor-liquid objects, and can meet various requirements of high and low pressure. At present, it occupies a pivotal position in the field of transportation pipes in the world.
During ERW pipe welding, heat is generated when current flows through the contact surface of the welding area. It heats the two edges of the steel to the point where one edge can form a bond. At the same time, under the action of the combined pressure, the edges of the tube blank melt and squeeze together.
Typically the maximum outside diameter of ERW tubing is 24″, and as a specialty manufacturer, Lai can go up to 26″.
