High-frequency straight seam resistance welded steel pipe, abbreviated as ERW, is a hot-rolled coil that is formed by a forming machine, and uses the skin effect and proximity effect of high-frequency current to heat and melt the edge of the tube blank, and press it under the action of a squeeze roller Welding to achieve production. At present, in the world's output of welded steel pipes, the output of ERW welded pipes accounts for about 80% of the total output of welded pipes.
