API 5L ERW Steel Pipe

ERW Pipe is high-frequency Electrical Resistance Welded Steel Pipe,The hot rolled coil is formed by forming machine,use the skin effect and proximity effect of high frequency current,make the edge of the tube heat and melted,weld it under the action of the extrusion roller to achieve to produce .It is widely used in long distance pipeline project for transmission of oil, natural gas, water, coal gas, mineral slurry etc., and also is applied in engineering such as chemical industry, electric power, irrigation, construction and piling etc.
