  ERW Steel Pipe plant in the production of spiral welded pipe process, we should pay attention to the following questions:

  1, API 5L ERW Steel Pipes marking: in the inspection of qualified spiral pipe oiling operation to prevent corrosion, and in accordance with the requirements of customers marking.

  2, flatten the milling edge: the use of anvil machine will be the original curled steel plate leveling, and then through the milling machine on both sides of the steel plate for double-sided milling, to achieve the required plate width, parallel side of the board and groove shape.

  3, shear molding: the steel plate along the spiral curled into a tube.

  4, butt welding: double-sided submerged arc welding technology for pre-welding, welding, external welding. The welded steel pipe was cut into a standard length using a plasma scale.

  5, visual inspection: by the professional and technical personnel to check some of the basic parameters.
