Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] Such as figure 1 and figure 2 As shown, a pipe outer wall coating maintenance device includes an air inlet 1 , an air outlet 2 , an upper base 3 , a lower base 4 and a sealing ring 5 . Both the upper base 3 and the lower base 4 are installed on the pipeline 7 . The upper base 3 is fixedly connected with the lower base 4 . The air inlet 1 is arranged on the upper base 3 . The exhaust hole 2 is arranged on the lower base 4 . The sealing ring 5 is arranged on the inner side of the upper base 3 and the lower base 4 where the pipe 7 is in contact with.

[0022] The upper base 3 and the lower base 4 are circular as a whole, and are divided into two symmetrical semi-circular rings with the dividing line 6 as the boundary. The upper base 3 and the lower base 4 are fixedly connected by glass glue. The inner wall of the upper base 3 and the lower ba...

Abstract

The invention belongs to the technical field of repairing of outer wall coatings of pipelines, specifically relates to a maintenance device for an outer wall coating of a pipeline, and aims at solving the problem that the outer wall coating of the pipeline cannot be maintained in a terrible environment. The device is capable of maintaining a new coating in case that the temperature of the outer wall of the pipeline is below the environmental dew point. The device is characterized by comprising an air feeding hole, an air exhausting hole, an upper base, a lower base and sealing rings, wherein the upper base and the lower base which are fixedly connected are mounted on the pipeline; the air feeding hole is formed in the upper base; the air exhausting hole is formed in the lower base; the sealing rings are arranged at the parts wherein the inner sides of the upper base and the lower base are in contact with the pipeline.

Description

technical field [0001] The invention belongs to the technical field of pipeline outer wall coating repair, in particular to a pipeline outer wall coating maintenance device. Background technique [0002] In the industrial field, it is often necessary to paint the outer wall of the pipeline for anti-corrosion treatment. The anti-corrosion coating on the outer wall often has multiple layers of topcoat, intermediate paint and primer. After each layer is painted, it takes a period of time for maintenance. Proceed to the construction of the next coat. However, on-site construction often encounters a relatively harsh environment, the surrounding environment has high humidity, and the temperature of the outer wall of the pipeline is lower than the environmental dew point, resulting in condensed water on the surface of the outer wall. After the coating is completed, the maintenance steps of the coating cannot be carried out. If the coating is not maintained sufficiently, the coatin...
