Galvanised Steel Pipe Milling hf tube mill Machine Welding With FFX Forming Technology

ERW273 high precision full automatic ERW tube mill making machine

This line is used to manufacture welded steel pipe of Φ114mm-Φ273mm with 2.0mm-10.0mm of wall thickness, can produce Square pipe 60*60 - 200*200mm.
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.

Product advantage:

1. High precision
   between level roller jumps 0.01,between frame and slide clearance ≤0.02, frame vertical degree ≤0.05, each frame parallel degree ≤0.1,steel pipe diameter and roundness error≤0.08
2. Use Japanese technology to make foreign clients requirment who need the high accuracy requirement
3. Schedulable use the worm gear and worm adjustment, the adjustment precision is high, energy accurately
4. The scraping scar can be adjusted 3D adjustment , scraper can along the steel circle ±20 ° rotation.
5. Round become square is Turkish head push square, can reduce mold weight, forming stable, uniform R Angle.
6. Level up shaft increase nylon damping block, reduce the impact to the shaft and bearing.
