Straight seam steel pipe is a kind of welded steel pipe, which refers to the steel pipe with the welding direction parallel to the longitudinal direction of the steel pipe. After the hot-rolled steel coil is formed by the forming machine, it is converted into a cylindrical shape, using high-frequency current skin effect and proximity effect or arc burning Welding is carried out below the flux layer, so that the edge of the tube blank is heated and melted under a certain extrusion pressure, and finally cooled and formed. It is widely used in my country's petroleum, metallurgy, construction, coal mines, ports, machinery and other industries.
