Many stainless steel industrial pipes need internal and external leveling for their weld bead, which requires internal leveling equipment for processing, and mandrel is a necessary hardware workpiece, which should be paid attention to in this design.

The diameter or inner diameter of the stainless steel pipe that can be processed by the internal leveling equipment is greater than 15, which is determined by the size of the mandrel. If the inner diameter is too small, the mandrel can not be designed, and the internal leveling operation can not be carried out, which is the first factor to be considered. Secondly, we need to consider the tolerance size and length design of the mandrel. Different pipes have different design requirements for the mandrel. The moving distance of the internal leveling equipment is different, and the length design of the mandrel is also different. This is something to consider. In addition, the material design should be considered. Because the mandrel of small-diameter pipe is small, it can be designed as a solid bar, and the operation will not be troublesome. However, the mandrel of internal leveling equipment for some large-diameter pipe needs to be considered. If it is still solid, it will be very heavy, and it will be troublesome for the operator. Now for the internal leveling of large-diameter welded pipe There are several solutions for mandrel. Please refer to the pictures in this article, but I won't introduce them here.

There is a certain technology in the design of the mandrel of the leveling equipment in the weld bead of stainless steel pipe, which can not be solved simply. There are many problems to be considered. If you also want to do industrial pipe, you may as well come to me. We will try our best to serve you.
