Why do stainless steel pipes need to be painted?
Prevent it from rusting :D:D:D
Isn't it stainless steel? Why does it rust? ? ?
It will also rust if the conditions are harsh.
Stainless steel pipelines generally do not need to be painted unless they are exposed to acidic environments for a long time.
Some coastal petrochemical companies require painting, saying it resists salt spray corrosion.
So if the conditions are harsh, you need to paint it :D
Stainless steel is most afraid of chloride ion corrosion. However, due to the influence of sea breeze, the seaside has high chloride ion content in the air, which will cause pitting corrosion on the surface of stainless steel. After corrosion, pitting will be formed on the surface, destroying the surface gloss.
Generally do not paint. Special situations need to be dealt with before painting.
There are several possibilities: 1. The factory has unified marking and coloring requirements for process pipelines ； 2. The operating environment has specific anti-corrosion requirements ； 3. The paint in stock is about to expire. In line with the principle of "waste is the biggest crime", paint wherever possible.
