High Precision Steel Tube Mill Line for Round Square Rectangular Pipes

ERW32 high precision steel tube mill production line

The mill is used to manufacture of round pipe of Φ12mm-Φ32mm with thickness of 0.5mm-2.0mm from cold-rolled and hot-rolled coil strip by means of unclosed tubular blank with its subsequent welding into tube, edge heating by means of solid state high-frequency welder, longitudinal seam welding in rolls of tube welding machine, cooling, further sizing or shaping and on-stream cutting of endless tube in measured lengths.

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.
