For square rectangular pipe, is it better to choose the round-to-square method or Direct-forming-technology(DFT)method?

Square rectangular steel pipe is the choice of round to-square forming method good, or choose the direction of the square forming method good? Square tube manufacturers to answer your questions.

There are three methods of forming a square tube, round to square, direct to square, and roll to square. Of these three methods, round-to-square and direct-to-the-square are the most common methods. So which of these two methods is better? Today I will take you through the distinction.

The advantages and disadvantages of round pipe into the square pipe: the advantages are good quality of round pipe into the square pipe, fast forming speed, equal internal angle R, and flat weld seam. The disadvantages are high forming power, relatively low material utilization, and the tendency to build up metal in the corners when producing thick-walled tubes, resulting in crushing and cracking.

Advantages and disadvantages of directly formed square tubes: the advantages are material saving and low energy consumption per unit. The disadvantage is that the inner corner R is not equal, the corners are thin, and the forming speed is slow.

After the technical development and improvement of Yuantai Derun Steel Pipe Manufacturing Group, the R angle of the directly formed square tube are very equal, while also saving material, low energy consumption per unit, and forming speed faster and the corners are thinner and more uniform.

In fact, after our practice, when round tubes are converted to square tubes, the quality of the formed steel pipe is good, compared to the direct into square forming technology, the R angle is instead relatively poorly controlled. However, no matter what kind of square tube forming method, the quality of our welded seam is the best in China. This is a point of confidence Yuantai people still have. And no matter which method you choose, our guarantee of quality is the same. When you buy a square tube, you choose Yuantai.

To sum up, each forming method has its advantages and disadvantages, to integrate their situation to choose the right method for them. If you are interested in what kind of rectangular pipe should use which forming method, you can consult our account manager, who will definitely give you a satisfactory answer.
