Pipe spraying equipment and spraying production line

The invention discloses spraying equipment, and particularly relates to pipe spraying equipment which comprises an equipment rack, a surface pretreatment device, a spraying device and a conveying rack are arranged on the equipment rack, and a pipe feeding device used for moving pipes from the surface pretreatment device to the spraying device is arranged on the conveying rack. The corrosion-resistant coating is processed by adopting a supersonic speed cold spraying technology, and a spraying material does not generate any phase state transformation, chemical change and serious material oxidation in the spraying process. A flue gas environment-friendly device is not required to be additionally arranged, and only a dust removal system needs to be connected. And no thermal stress is generated in the cold spraying coating, and the risk that the coating falls off is avoided. Derusting and spraying on the surface of the pipe are synchronously carried out and completed in the same equipment, carrying and transferrin
