"ERW steel pipe" is a high-frequency straight seam resistance welded pipe, full name Electric Resistance Welding, abbreviated as ERW, used to transport oil, natural gas and other vapor and liquid objects, can meet various requirements of high and low pressure, currently in the world's transportation pipe The field occupies a pivotal position.
ERW stands for resistance welding. Resistance welding has the characteristics of high production efficiency, low cost, material saving, and easy automation. Therefore, it is widely used in aviation, aerospace, energy, electronics, automotive, light industry and other industrial sectors. It is one of the important welding processes. one. The biggest difference between ERW steel pipe and seamless steel pipe is that ERW has a weld seam, which is also the key to the quality of ERW steel pipe.
