Analysis of the calculation of stainless steel elbow

At the corner of the pipeline, in addition to the standard elbow, mostly by bending pipes made of stainless steel elbow. Two methods of making stainless steel elbow can be cold and hot bending, cold bending forming is the pipe will be at room temperature; hot bending is the pipe is heated to a specified temperature for bending forming.
Cold-formed applicable in small diameter tube a bending; bending are commonly used in large diameter and thick wall pipe, such as high pressure pipes bent. It can guarantee the stainless steel elbow quality bending stainless steel pipe fittings, previous work mostly depends on manual operation, high labor intensity, low efficiency, in order to adapt to the development of chemical production, there are many kinds of specialized stainless steel elbow’s device, greatly improving the stainless steel elbow work quality and efficiency.
Pipe bend, pipe elbow is stretched, the tube wall of the inner side is compressed, so will the stainless steel elbow in the process of wall thinning. This phenomenon in more people and diameter of the bend radius is smaller under the condition of more obvious, in order to ensure the quality of stainless steel elbow, avoid lateral wall thickness, bending radius should be the reasonable choice of stainless steel elbow.
In practice, the bending radius of various pipes can be selected according to the nominal diameter of the pipe. At the same time, the method of the stainless steel elbow and the thickness of the pipe wall, as well as the filling material and other factors are also considered.
