Thickness 1.5mm-20mm ERW Carbon Steel Direct Square Tube Mill
It is directly roll the steel strip and bend it to square & rectangular shape, then weld it to finish the formation.
Direct Square to Square Pipe Mill greatly avoids the axial force and side abrasion and reduces roll forming steps while ensuring the quality. Meanwhile, this method of our direct square tube mill line also effectively reduces the power wastage and roller abrasion.

Square Tube Machine Working Flow:
Material uncoiling -Material storing - Roll forming - High frequency welding - Burr removing - Water cooling -Sizing - Straightening -Flying saw cutting - Pipe collecting
Characteristics and Advantages:
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 2.4-3% than round into square & rectangle,it can save the consume of raw material.
4).It adapt the multi-point bending way, avoid the axial force and side abrasion, reduce the forming step while 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 roller,low the cost about 80% on roller, Fast the bankroll turnover, short the time one new product design.
We can also design square tube machine depends on customer’s requirement.
