3. If it is in the air containing a lot of sulfide, carbon oxide, and nitrogen oxide, stainless steel shower pipe it will become water when it is cold. Form sulfuric acid, nitric acid, nitric acid liquid. It will also cause chemical corrosion and cause the rust of the stainless steel decorative pipe.
