Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe processing, in particular to a spraying device for processing anti-corrosion steel pipes. Background Art

[0002] The main purpose of anti-corrosion steel pipe spraying is to protect the surface of the steel pipe from chemical corrosion, extend its service life, and reduce maintenance costs. Anti-corrosion steel pipe spraying is achieved by covering the surface of the steel pipe with a layer of anti-corrosion paint or coating to prevent or slow down the corrosion caused by chemical or electrochemical reactions during transportation and use. This treatment method can effectively protect the steel pipe, especially in humid underground environments or exposed to air, and can maintain good performance, thereby reducing maintenance costs. There are many types of anti-corrosion coatings, and their performance and uses vary, but the common goal is to form a continuous covering layer of insulating material on the metal surface to insulate the metal from the electrolyte in direct contact with it, prevent the electrolyte from directly contacting the metal, and set a high resistance so that the electrochemical reaction cannot occur normally, thereby achieving the purpose of corrosion prevention.

[0003] The existing spraying device for processing anti-corrosion steel pipes is not convenient for adjusting the position angle of the steel pipe during the spraying process. Most of the equipment needs to turn the steel pipe over after spraying one side, and spray the other side of the steel pipe. This will make the spraying of the steel pipe uneven, reduce work efficiency, and in the process of spraying the steel pipe, the anti-corrosion paint is lost a lot, and the cost of use is high.
