What is the condition of the inner wall of the stainless steel pipe as shown in the figure below? Does it affect its performance?

I’d like to ask the forum members: lol
Residual media – I’m not sure what medium is being transported through your stainless steel pipes?
Uh, I forgot to mention it – new pipes. . .
It is also possible that the pipes were contaminated during storage and transportation
With new pipes, it refers to the fact that the pipes aren’t sealed, allowing dust or sewage to enter them; the residues that remain after they dry out.
Just rinse it out; water must have gotten in due to the rain or something
Methods for beautifying pipes (sandblasting): The inner and outer surfaces of the pipe should have a uniform appearance; this is likely due to the fact that it wasn’t cleaned thoroughly after the treatment. After spraying the inner and outer surfaces, it is possible to cover up defects such as small cracks on the surface. Cheap items are just like that; there’s nothing you can do about it.
