It is believed that many people have encountered a problem, that is, when purchasing welded pipe mechanical equipment, it is good, but after a period of time or several years, it is found that the welded pipe mechanical equipment is deformed. Then why is the welded pipe mechanical equipment deformed, and how to solve it?

In fact, it is not uncommon for welded pipe mechanical equipment to deform, because early welded pipe equipment did not have a perfect processing and manufacturing process, and many links were not so perfect, so it is normal for defects to occur later. The deformation of mechanical equipment for welded pipe is mainly caused by the change of internal stress, because the change of internal stress is invisible to us. After a long time, it will occur in the form of deformation or other conditions, such as fracture, which are possible. Then how to deal with the internal stress? It is necessary to release the internal stress of mechanical equipment parts of welded pipe before production. If conditions permit, it is safer to place the processed workpiece on the open ground for several months, or use some machinery to assist the internal stress release, but the effect is not good compared with natural static release.

Dear customer, has your welded pipe mechanical equipment been deformed? The next time you buy welded pipe equipment, you must pay attention to the internal stress change factors.
