      Briefly explain the control mode of distance in pipe bending processing

      Elbow products are often seen around us, but how much do you know about its processing process? In particular, some details are needed. Among them, the control of elbow processing distance is a difficulty. Let's introduce this aspect and see how to avoid various defects caused by too large distance?



      The elbow processing distance must be controlled. If it is too large, it will cause lap welding and torsion and affect the quality of the elbow. In fact, if you want to avoid the development of this situation, the jaw distance after pipe bending and upsetting should be determined according to the thickness of the strip steel. Generally speaking, the thinner the thickness of the strip steel for pipe bending, the smaller the jaw distance after upsetting, so as to meet the requirements of the process.


      The reason why lap welding and torsion occur in the distance assembly is mainly because the distance assembly makes the upsetting pressure too large, so that the hot metal at the welded junction will be completely extruded. In this way, the processing and welding strength of elbow will be reduced. It is not surprising that there are adverse phenomena.
