ERW steel pipe is the straight seam resistance welding pipe, the English Electric Resistance Welding, abbreviation for ERW.
ERW steel pipe is produced by forming the hot rolled rolling plate through the molding machine, melting the edge of the pipe blank and performing pressure welding under the extrusion roller. The uniform wall thickness can be controlled at about ± 0.2mm.ERW production process has high production efficiency, low cost, material saving, easy automation and other characteristics, widely used in aviation, aerospace, energy, electronics, automobile, light industry and other industrial fields.
