Flattening Welded Tube Mill 8mm , Friction Saw Industrial Tube Mills

HG219*8mm high frequency welded tube mill machine

This line is used to manufacture welded steel pipe of Φ89mm-Φ219mm with 2.0mm-8.0mm of wall thickness, can produce profiled pipe also within the limit of processing round pipe. After we absorbed advanced pipe making technology from both abroad and domestic, our innovative designed production line and each single unit of the production line is not only economical but also practical.

Brief introduction of ERW tube mill & pipe mill

  • The ERW tube mill & pipe mill is a series of machines that builds longitudinal weld seam tubes and pipes with steel strips of certain width.
  • It starts by uncoil and flatten the slitted steel coils into steel strips.
  • The flattened steel strips will then be inserted into the forming machine and the roller tolling in the machine will roll the strip to round pipe shape.
  • The rolled strips will then be sent into the weld box where the tube is welded by a high frequency solid state welder.
  • The welded tubes will be formed to expected shape or size in a sizing machine. Finally the tubes will be cut to length and bundled.
