Panting Service

Painted steel pipe is to spray different colored coatings on the surface of the steel pipe in order to improve the corrosion resistance and aesthetics of the pipe. Painted steel pipes include spray-coated steel pipes and painted steel pipes.

Spray-coated steel pipe is first acid-washed, galvanized and phosphated, and then electrostatically sprayed. The advantages of this method are strong adhesion of the coating, not easy to peel off, good protective performance, bright and beautiful colors; the disadvantage is that the cost is relatively high, and special spray equipment and highly skilled personnel are required to operate.
Painted steel pipe is directly spray-painted different colored coatings on the surface of the steel pipe without acid washing, galvanized nor phosphating, in order to improve the corrosion resistance and aesthetics of the pipe. The advantages of this method are relatively low cost and simple and convenient processing; the disadvantages are weak adhesion, difficult to achieve long-term corrosion resistance effect, and relatively monotonous color.

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.
