Problems solved by technology

[0002] In the industrial production of petroleum, chemical industry, etc., the raw materials of gas or liquid are generally transported through pipelines, and the physical and chemical properties of these raw materials are complex, and most of them are corrosive. Therefore, it is necessary to carry out anti-corrosion treatment on the inner wall of the pipeline, but through The anti-corrosion layer on the inner wall of the pipeline will be eroded during long-term raw material transportation, which requires regular repainting of the anti-corrosion layer on the inner wall of the transportation pipeline. If the corrosion is serious, the pipeline needs to be replaced directly; the transportation of existing corrosive materials Ground transpo

Abstract

The invention discloses a method and device for coating the interior of a pipeline with a coating, and relates to a coating method and device for a coating. The inner wall of the pipeline can be coated with the coating only through four steps of earlier-stage preparation, coating machine assembling, coating filling and pipeline interior coating by utilizing the device. The method and device for coating the interior of the pipeline with the coating is particularly applicable to coating the inner wall of a specially-shaped pipeline with an anti-corrosion material, a two-hair-ball structure is utilized, the coating is sealed between two hair balls, a flexible drive shaft is connected with a power device so as to obtain liner displacement and rotation power, then, the purpose of coating is achieved, material consumption is small, the coating effect is good, operation is not affected by pipeline shapes, and the application range is wide.

Description

technical field [0001] The invention relates to a paint coating method and a device, in particular to a method and a device for coating paint in a pipeline. Background technique [0002] In the industrial production of petroleum, chemical industry, etc., the raw materials of gas or liquid are generally transported through pipelines, and the physical and chemical properties of these raw materials are complex, and most of them are corrosive. Therefore, it is necessary to carry out anti-corrosion treatment on the inner wall of the pipeline, but through The anti-corrosion layer on the inner wall of the pipeline will be eroded by long-term raw material transportation, which requires regular repainting of the anti-corrosion layer on the inner wall of the transportation pipeline. If the corrosion is serious, the pipeline needs to be replaced directly; Ground transportation is adopted, because it facilitates the dismantling of the pipeline and the anti-corrosion coating on the inner...
