High Frequency Welded Pipe Mill
Our high frequency(HF) welded pipe mill has everything you need to produce high-quality HF welded pipes in a wide range of outer diameters from 8mm to 89mm and with a maximum wall thickness of 4.5mm.
The complete HF welded pipe mill is made up of an entry section, mill section, cut-off section and finishing section, the steel pipe manufacturing process including:
Scrolling Up→ Uncoiling → Shear and Welding→ Spiral Accumulator→ Forming→ HF induction Welding→ External Burr Removing→ Cooling → Sizing→ Flying Saw → Run Out Table →Inspecting→ Packing→ Warehouse
Features
- Suitable for processing carbon steel
- Round and rectangular pipes can be produced with this equipment
- Production speed can reach up to 120m/min
- Diameter error tolerance is within 0.5/100 of the pipe’s OD
Forming process
Round Pipe | Cold roll forming process | Good roller design |
Square & Rectangular Pipe | General round-to-square process | Stable forming process |
Round to square with turkshead unit | Good pipe quality, achieve the same wall thickness as that of round pipe |
