RT76 High Frequency Pipe Mills – 80mm×4.0mm
Name: High Frequency Pipe Mills
Model: RT76 (80mm×4.0mm)
We can also supply the customized machines.

  • Features:

RT76 High Frequency Pipe Mills is a series of machines that builds longitudinal weld seam pipe with steel strips of certain width. It starts by uncoil and flatten the slit steel coils into steel strips. The flattened steel strips will be inserted into the forming machine and the rollers in the machine will bend the strip to a round pipe shape. The round pipe will then be sent into the weld box where the tube is welded by a high frequency or solid state welder. The welded pipe will be formed to expected shape (round/ square/ rectangle etc) or size in a sizing machine. Finally the pipe will be cut to length and bundled.

  • Applications:

1. Water Pipe

2. Heating Pipe

3. Low-pressure Process Pipeline
