Coating and leveling device for nano coating of corrosion-resistant composite steel pipe

Abstract

The invention relates to the field of nano coatings, in particular to a coating and leveling device for a nano coating of a corrosion-resistant composite steel pipe. According to the technical scheme, the coating and leveling device for the nano coating of the corrosion-resistant composite steel pipe comprises a bottom plate assembly, a cleaning unit, a conveying unit, a spraying and leveling unit and a control screen, and the bottom plate assembly is connected with the cleaning unit. Dust attached to the surface of a steel pipe is cleaned, then the cleaned steel pipe is conveyed to a designated position, then the inner ring face of the steel pipe is evenly sprayed with the nano coating, then the outer ring face of the steel pipe is evenly sprayed with the nano coating, then the steel pipe is made to rotate, the nano coating is made to be leveled, thus the nano coating is uniformly coated on the outer ring surface and the inner ring surface of the steel pipe, so that the waste is avoided, and the later product quality is improved.

Description

technical field [0001] The invention relates to the field of nano-coating, in particular to a nano-coating leveling device for corrosion-resistant composite steel pipes. Background technique [0002] Composite steel pipe is a composite of steel and other substances. It has the common advantages of both. For example, composite steel pipe has super compressive and tensile properties. In addition, it is resistant to corrosion, acid and alkali, and wear. The damage is also very good. The composite steel pipe will not accumulate dirt or breed microorganisms due to long-term use, which can better ensure the original essence of the fluid. The composite steel pipe has excellent insulation properties, and can be used in many special applications. It is used in the environment to protect many wire devices and other items, which can improve the overall construction accuracy and ensure the final effect of the construction. [0003] At present, my country has continuously developed new ...

Problems solved by technology

[0005] In order to overcome the current situation, my country has continuously developed new oil fields, which has led to a rapid increase in the demand for water injection pipes. In order to meet the needs of the market, there are a large number of composite steel pipes of uneven quality on the market. During the production process of composite steel pipes, it is necessary to The inner ring surface and the outer ring surface of the steel pipe are coated with nano-coatings. In the prior art, it is impossible to uniformly spray the nano-coating on the inner ring surface and the outer ring surface of the steel pipe, and make the nano-coating leveling, which leads to A lot of waste is caused, which leads to the disadvantage that the product quality cannot be guaranteed. The technical problem to be solved is: to provide a corrosion-resistant composite steel pipe nano-coating coating leveling device
