Under normal circumstances, the seamless steel pipe has an oxide film on the surface after pickling. After pickling, the surface is smooth, and even if painted, it will quickly fall off.

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

1. The function of the paint coating is to prevent corrosion, and the seamless steel pipe is corrosion-resistant, so do not paint, painting is unnecessary supply and demand.

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

3. Stainless steel itself has strong corrosion resistance. The coating is mainly to prevent rust, corrosion, etc., and needs to be coated with carbon steel and other materials.

Usually stainless steel pipes do not need to be painted, but can also be painted under special conditions, such as in a marine environment. 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 circumstances, stainless steel pipes do not need to be painted, and the paint will only increase costs and waste energy. And the effect is not obvious.
