Special Shaped Stainless Steel Tube

The forming method is steel pipe bending forming, what we also called bending. Deformed steel tube bending is divided into two kinds, a kind of real bending, another empty bending.

The advantage of rectangular tube bending is that the real solid curve will be relatively small, and it is more accurate, and the production time and roller accuracy as well as the internal rebound after the steel tube forming, we can ensure accurate.

A certain shortcomings of instant bending is that the main stretch of time will lead to a thin steel tube. The real bending rectangular tube bending, the stretch bending of agricultural products, led to the bending line in the direction of the length of the deformed steel tube length is shorter, and the metal content will decrease for stretch.

Empty rectangular pipe bending production, the outside roller with square and the walls of the profiled steel tube, and the metal bending, bending the time of the individual, steel pipe bending line will produce certain compression, compression effect, so the longitudinal variable length zigzag line, rectangular tube bending of metal, will become the thick air bending, compression or thickening effect.

These two kinds of production methods including two basic ways square and rectangular pipe production of profiled steel pipe forming, according to the requirements of different products, select the appropriate process configuration. It is important to note that when stretched and compressed,it may lead to the deformation of rectangular tube.
