High Frequency Welded Pipe Making Machine Max 50m/Min Speed CE BV Standard

1. 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.

• 2. Function

  This pipe is used especially for Petroleum, Natural gas, City gas, Pipe network, Chemical industry, Electricity, Steel truss, Water and Gas pipeline; it is widely used for a variety of pressure pipelines.
