Stainless steel welded pipe equipment can be welded pipe there are a lot of states, the most important form has two, one is the pipe with weld seam, one is the weld seam leveling, this is mainly decorative pipe and industrial pipe general performance, there are individual industrial pipe also requires a weld, the purpose is to improve the weld quality of welded pipe.

As decorative tube of stainless steel welded pipe equipment and weld industrial tube of stainless steel welded pipe equipment have commonly weld seam inside weld pipe wall, the difference is that some inside weld appear dark brown, some appear white, it is also welded pipe after pipe state of different places, appear this kind of situation is usually caused by atmosphere protection role. And for some other pipe requirements to level the inner weld bead, this need to use industrial pipe stainless steel welded pipe equipment, equipped with internal leveling equipment, can be very good flattening weld bead height, so that the weld and base material smooth transition, these are another state of embodiment. There are also some differences between annealed and non-annealed states, which I will not elaborate here.
