FAQ:
1: Q: What’s the square tube ?
A: Square tube of the name suggests, it is a kind of tube body, a lot of material can be formed in the body of the body, it is medium, what use, used in what place, most of the square tube to the majority of steel pipe, Flat, curled, welded to form a round tube, and then rolled into a square tube by the tube and then cut into the required length. Generally 50 per pack of pipe in the spot to the large size of the majority of 10 * 10 * 0.8-1.5 ~ ~ 500 * 500 * 10-25, square tube according to the use of structured square tube, decorative side tube, building side tube , Mechanical square tube and so on.
Square tube, is a square pipe of a call, that is, equal length of the steel pipe. Is made of steel by the process of rolling.
In addition, the pipe is cut into a square tube and then cut into a desired length.

Forming method of square tubes :
1, real bend
Stretch, as the name implies is the compaction of the bending, the actual bending inside and outside the roller and the inner and outer wall of the two-way compaction.
1) the advantages of a solid bend is a small rebound, forming accurate, and as long as the roller is accurate, the inner corner of the R is more accurate.
2) The disadvantage of a solid bend is a tensile / thinning effect. First, the actual bending will produce bending at the bend, stretching effect to shorten the length of the bending line; second, the actual bending of the metal will be thinning due to stretching.
2, empty bend
The bending is caused by the uniaxial contact between the outer roll and the outer wall of the tube to form the bending moment. The bending will cause the bending line to be compressed. The compression effect causes the bending line to be elongated longitudinally, This is the compression / thickening effect of the empty bend.
1) The advantage of the air bend is that it can be bent at the moment when it can not be carried out, such as the upper side / side of the square tube and the simultaneous bending and finishing. The empty bend can also bend the inner corner of R <0.2t without breaking the wall.
2) The disadvantage of the empty bend is that the upper and lower sides of the roll and the lower roll simultaneously produce pressure, the forming force easily beyond the critical point, resulting in edge instability concave, and will also affect the unit stable operation And molding quality. This is also a square tube and tube round bending when forming different characteristics.SHS
