How to connect ordinary seamless steel pipes and stainless steel pipes?
Thread Content
The compressed air pipes in the workshop are made of 8163 seamless steel pipes; however, some pipes that pass through clean rooms require stainless steel pipes. How can stainless steel pipes be connected to seamless steel pipes?
Use a flange conversion! Carbon steel is connected to carbon steel flanges, and stainless steel is connected to stainless steel flanges. It can also be welded.
Are there paired flanges that are half carbon steel and half stainless steel?
Flange connection or welded connection. . . This isn’t a problem
It is possible to query the \"Table of recommended welding materials for welding different steel grades together\"”
It’s good that I have your advice. If working directly, it’s sufficient to use welding materials that are the same as or of a higher grade than those used for the stainless steel pipe base material
Flange connections and welding are both theoretically feasible. However, in practical work, I believe that flange connections are more convenient and safer than welding; in the long run, they are also safer and more economical.
It is best to use flange conversions: carbon steel should be connected using carbon steel flanges, and stainless steel should be connected using stainless steel flanges. It can also be welded.
Welding is not recommended; use flange connections instead
