Introduction of Painted steel pipe
Painted steel pipes are coated with different colors on the surface of the pipes to improve their corrosion resistance and aesthetics. Painted steel pipes include spray-coated steel pipes and painted steel pipes.
01
The spray-coated steel pipes is first treated with acid pickling, galvanizing, and phosphating, and then subjected to electrostatic spraying. The advantage of this method is that the coating has strong adhesion, is not easy to peel off, has good protective performance, and has bright and beautiful colors; The disadvantage is that the cost is relatively high, requiring special spraying equipment and highly skilled personnel to operate.
02
Painted steel pipes are coated with different colors of paint directly on the surface of the pipes, without the need for acid washing, galvanizing, or phosphating, to improve the corrosion resistance and aesthetics of the pipes. The advantages of this method are relatively low cost, simple and convenient processing; The disadvantage is weak adhesion, making it difficult to achieve long-term corrosion resistance, and the color is relatively monotonous.
When using painted steel pipes, it is necessary to select the appropriate paint type, color and thickness according to the specific conditions of use and requirements. At the same time, it should be ensured that the surface of the steel pipe is dry, clean and smooth to ensure the coating adhesion effect and service life.
