Problems connecting American standard stainless steel pipes and national standard ordinary carbon steel pipes
Thread Content
American standard stainless steel pipes and national standard ordinary carbon steel pipes are connected by flanges. If the flange sizes are the same, what are the sizes of the two corresponding pipes? For example, the DN10 national standard carbon steel pipe and the corresponding DN10 flange should correspond to the DN10 American standard stainless steel pipe?
I think the pipe diameter should be the same, DN10 of course

I have seen that the two connected pipes in the process are different, so I asked this question. I don’t know what the facts are?
You need to check the outer diameter and wall thickness of the pipe. There is a lot of difference between the American standard and the national standard.
Reply 5# me108924 You mean that the outer diameters are aligned, right? The stainless steel flange should be selected to correspond to the stainless steel pipe, right? Then please specify how to check the outer diameter of American standard stainless steel?
You can check the standard. It is best to have the same inner diameter to avoid pressure problems.
Reply to agangshine 6#, I think the outer diameters are the same and can be welded, so there won't be any big problems, unless there is a problem with the selected scale process itself.
