Steel Bend

Steel bends and steel elbows are both very common pipe fittings which are used to change the flowing direction in a piping systems. In addition to pipe fittings for connecting , elbow pipe also refers to a processing method. It is to Bend the straight pipe through the processing method to achieve the purpose of changing the circulation direction of the pipeline. The manufacturing process and the finished product are called pipe bend.

In order to ensure that the wall thickness of the bending part is no less than that of the straight pipe part, the minimum radius of the pipe bending should be 3D( the D means nominal diameter of this bend). The specific size depends on the operating conditions. That is to say, radius is not restricted as long as it exceeds 3D, which can be 3D or 3.2D, even 4D, 5D, 6D and 8D are also acceptable. In addition, the angle of the bend can be in any degree, some times there are also custom-designed bends which are 22.5 °, 45 °, 90 °, 135 °, 180 °, 270 ° and so on.
