GR B X42 X46 X70 3PE Coated High Frequency Welded Pipe
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.
ERW steel pipe used for transporting gas and liquid objects such as oil and gas, could meet the low and high pressure requirement. In recent years, with the development of ERW technology, more and more ERW steel pipe used in the oil and gas fields, automobile industry and so on.
