1.Summary: It is sprayed and painted by the zinc wire under the strong arc on the surface of pipe, then protective film formedin order to improve its corrosion resistance. 2. Equipment Components It is composed of Aligning & Stop-pusherUnits,Lifting Device, Walking Unit, Pipe Clamping and RotatingDevice,Zinc coating and Walking Device,Dedusting and Defending Device,Hydralic System and Electric Control System. 3. Technical Characteristics: 3.1. Ithas full automation for the process of zinc spray-painting with high productivity. 3.2. It can be sprayed and painted by one machine for the pipe with awide variety of specifications, the parameters of zinc spray-painting can be automatically adjusted as per different pipe sizes. 3.3.The whole process of zinc spray-painting is carried out under the environment of negative pressure; the air through secondary dedusting discharge meets the requirement of protecting the envirnment, whichhas no harmfulness for the human body.
