ERW steel pipe production process flow chart
ERW high-frequency welded pipe is a hot-rolled coil formed by a forming machine, which uses the skin effect and proximity effect of high-frequency current to heat and melt the edge of the tube blank, and then carries out pressure welding under the action of extrusion rollers to achieve production. It is mainly used for conveying low-pressure fluids such as water, sewage, gas, air, heating steam and other purposes.
