Analysis of Weld Seam Distance Adjustment for Seamless Steel Pipe

In the processing of seamless steel pipe, there is usually a problem that can not be ignored, that is, the weld. In order to ensure the performance of seamless steel pipes, we need to take some measures to control the weld distance between seamless steel pipes. Otherwise, if the gap is unreasonable, its performance will be affected. Next, let's learn the main content.


Generally, in order to ensure the performance of seamless steel pipe as much as possible, we control the gap within an appropriate range of 1-3mm, and ensure that the end of the weld is flush. If the gap is not well controlled, what negative impact will it have? If it is too large, it is easy to reduce the proximity effect, which will eventually lead to poor connection and fracture.


If the remaining gap is too small, it is easy to affect the surface quality of seamless steel tube under the extrusion. Therefore, we need to take some measures in advance to avoid these problems as much as possible. First, we need to control the welding temperature. In fact, the welding temperature will not only affect the welding effect, but also affect its overall performance.


Another problem that needs to be paid attention to is that the size of extrusion pressure needs to be adjusted properly. We know that when processing seamless steel pipe, if the extrusion pressure used is too large or too small, it will also lead to different changes in its weld. For example, if the extrusion pressure is too small, the strength of the weld will be insufficient and it is easy to crack; if the extrusion pressure is too large, some defects will appear in the weld.


Therefore, in the whole process, we must ensure to maintain the appropriate temperature conditions and pressure. Only in this way can we control the welding gap of seamless steel pipe. Reasonable gap control can ensure the performance of seamless steel pipe.
