Abstract

[0002] At present, the inner wall anti-corrosion of long-distance large-diameter pipelines is usually processed in sections at the factory, and then transported to the use site for unified welding. In order to extend the service life of the pipeline, the inner wall of the welded large-diameter pipeline needs to be anti-corrosion treated. However, the anti-corrosion equipment is large and the cost of moving it to the site for anti-corrosion treatment is high; secondly, the anti-corrosion layer on the inner wall of the pipeline that has been used for a certain number of years is easily damaged, resulting in a shortened service life of the pipeline. If you want to save costs and continue to use the pipeline, you need to remove rust from the inner wall of the pipeline after a certain period of use and spray the anti-corrosion material again.
