Black Steel Tube Production Line

Reduce 60% roller cost, save roller changing time, increased production efficiency

Square & rectangular Pipe

General round-to- square process

Stable forming process

Good pipe quality, reach same wall thickness with round pipe

Directly squared

forming technology

1) Compare with round into square&rectangle forming way,this way is better for the shape at the edge of cross section,comparatively, semi diameter of inner arc is

Small,and the brim is flat,outlook is regular.

2) the whole line load is low .especially the sizing parts.

3)The width of steel strip is small about 243% than round into square & rectanglejt can save the consume 

of raw material.

 4) It adapt the multi-point bending way, avoid the axial forming force and side abrasion, reduce the forming step while technology ensure the quality,meanwhile it reduce the power wastage and roller abrasion.

5) It adapt the combined type roller on the most of the stands.it realize that one set of roller can produce dozens of square&rectangle pipe with different specification,it decrease the store of rolleclow the cost about 80% on roller, Fast the bankroll turnover, short the time one new product design.
