Although both the raw materials are entirely different, it should be noted that the quality of end product tubes, entirely depends upon both factors quality control during the manufacturing process and the initial
ERW carbon steel pipe vs spiral pipe:First, the difference between the production process ERW carbon steel pipe is the hot rolled coil through the continuous roll forming, the use of high-frequency current skin effect and proximity effects, so that the edge of the coil heat fusion, pressure in the squeeze roller under pressure welding to achieve production.

Cold Rolled Steel Coil . The Application of ERW Steel Pipe in Oil and Chemical IndustryWhen selecting materials, designers mainly consider whether the material is reliable and rarely consider the cost of materials. Therefore, it is not possible to boldly use erw steel pipes. (2) The investment system of petrochemical enterprise construction projects restricts the initiative to select erw steel pipes and reduce costs.
