The invention belongs to the technical field of steel pipe manufacturing, and particularly relates to a steel pipe surface anti-corrosion coating spraying process. The steel pipe surface anti-corrosion coating spraying process comprises the following steps that 1, shot blasting treatment is performed, specially, shot blasting is performed on the surface of a steel pipe, burrs on the surface of thesteel pipe are removed, and so that the surface of the steel pipe is flat; 2, derusting treatment is performed, specially, the surface of the steel pipe is cleaned with a hydrochloric acid solution,and oxide skin and rust on the surface of the steel pipe are removed; 3, washing treatment is performed,specially, the surface of the steel pipe is cleaned with hot water, and residual hydrochloric acid solution on the surface of the steel pipe is removed; 4, drying treatment is performed, specially, the steel pipe is transferred to a hot blast stove, and the surface of the steel pipe is subjectedto the hot air drying treatment; and5, the spraying treatment is performed, specially, the dried steel pipe is placed on a steel pipe surface anti-corrosion coating spraying device through driving, and the dried steel pipe surface is subjected to spraying and drying treatment. The step five is adopted, during the spraying process of the steel pipe surface anti-corrosion coating spraying device onthe surface of the steel pipe, the steel pipe automatically generates a uniform material effect, and the device itself is protected while the spraying effect is improved.
