Recently, many customers are inquiring about the purchase of welded pipe machine, and they are also communicating about some technical links. One of the key technical points is why nitrogen should be added to welded pipe production. Here I give you a brief introduction, for your understanding.

Welded pipe production is a process in which the steel strip is crimped and formed by the welded pipe machine, and then welded to the welded pipe.One of the most important points is to ensure the welding quality of the weld, because the unqualified welding, will reduce the strength of the pipe and many other adverse factors. Therefore, nitrogen should be injected into the welding part of the welding pipe machine for protection. Through the protection of nitrogen, the oxidation reaction in the process of welding pipe can be effectively reduced, so as to realize the protection of welded pipe.
