Product Description
Direct Square Tube Mill Line is mainly used to produce the square and rectangular tubes directly, from square to square or rectangular to rectangular directly. As a professional square tube machine manufacturer, Hangzhou Roll Forming offers high-end square tube mill production line with consistently high quality.
Characteristics and Advantages of Direct Square Tube Mill Line
Compare with a round to square or rectangular roll forming method, directly roll forming to the square or rectangular method is better for the shape at the edge of cross-section, comparatively, semi-diameter of the inner arc is small, and the brim is flat, the outlook is regular.
The tube mill line load is low, especially the sizing machine.
The width of the steel strip is reduced by about 3% compared with around to square or rectangle, so this direct square tube mill line will save the consumption of raw material.
Directly roll forming method adapts the multi-point bending way, which 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.
Directly roll forming method adapts the combined type roller on most of the stands, this realizes that one set of rollers can produce dozens of square or rectangle tubes with different specifications. This decreases the store of rollers, lowers the cost of about 80% on rollers.
Which is Stronger Round or Square Tubing?
To answer this question, we have to take various factors into consideration. With all the things being equal, the square tube mill tends to have more steel material per diameter. As a result, it will be more resistant to the torsion force and it will be more suitable for the fabrication and application of reinforcing gussets. However, when it comes to the situation, where the internal pressure or force exists, the rounded pipe will, on the contrary, be "stronger" than the squared ones due to its circular structure.
