  Does the 304 stainless steel tube need to be painted? ? It is usually not necessary to paint stainless steel tubes. Under normal circumstances, the 304 stainless steel tube has an oxide film on the surface after pickling, and the surface is smooth after pickling, even if the stainless steel tube is painted, it will fall off quickly.

  Stainless steel was originally an alloy steel with good corrosion resistance. The purpose of surface coating is nothing but corrosion resistance. Therefore, painting stainless steel tubes is a waste. The role of the coating is to prevent corrosion, stainless steel is resistant to corrosion, so do not paint, do more paint rings or logos on the coating line.

  1, the role of paint coating is anti-corrosion, 304 stainless steel pipe is corrosion-resistant, so do not paint, brush paint is redundant supply and demand.

  2, 304 stainless steel thick-walled pipe does not meet the basic consensus, the coating may be confused with the carbon steel pipe, causing unnecessary trouble during the construction process.

  2, stainless steel itself has strong corrosion resistance, the coating is mainly to prevent rust, corrosion, etc., need to coat carbon steel and other materials.

  Stainless steel pipes are usually not required to be painted, but can also be painted under special conditions, such as in marine environments. In addition, many foreign companies need to coat thick-walled stainless steel pipes. Therefore, this is not a special requirement of the customer. Under normal conditions, stainless steel tubes do not need to be painted, and coatings only increase costs and waste energy. And the effect is not obvious.
