  Generally, the spiral steel pipe manufacturer has oxide film on the surface after pickling, and the surface is smooth after pickling. Even if the stainless spiral steel pipe is painted, it will fall off quickly.

  Stainless steel is originally an alloy steel with good corrosion resistance. The purpose of surface coating is corrosion resistance. Therefore, painted stainless spiral steel pipe is a waste. The function of coating is to prevent corrosion. Stainless steel is corrosion-resistant, so do not paint. Make more paint rings or marks on the coating line.

  1. The function of paint is to prevent corrosion. The spiral steel pipe manufacturer is corrosion-resistant, so do not paint. Painting is redundant.

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

  3. Stainless spiral steel itself has strong corrosion resistance. The coating is mainly to prevent rust and corrosion. Carbon steel and other materials need to be coated.

  Generally, stainless spiral steel pipes do not need to be painted, but they can also be painted under special conditions, such as in marine environment. In addition, many foreign companies need to coat thick wall stainless spiral steel pipes. Therefore, this is not a special requirement of the customer. Under normal circumstances, stainless spiral steel pipes do not need painting, and the coating will only increase the cost and waste energy. And the effect is not obvious.
