Anti-corrosion and heat-insulation processing method for petroleum pipeline

Abstract

The invention relates to an anti-corrosion and heat-insulation processing method for a petroleum pipeline. The anti-corrosion and heat-insulation processing method for the petroleum pipeline comprisesa bottom plate, a moving device and a coating device, wherein the moving device is arranged at the upper end of the bottom plate; and the coating device is arranged in the middle of the upper end ofthe moving device. The anti-corrosion and heat-insulation processing method for the petroleum pipeline provided by the invention can solve the problems that when an existing petroleum pipeline is subjected to anti-corrosion treatment, an anti-corrosion coating is poor in adhering effect and an anti-corrosion layer is easy to fall off since a treatment effect on the surface of the pipeline is poorand impurities such as oil stains, rust stains and welding slags on the outer surface of the pipeline cannot be treated cleanly, and meanwhile, when the surface of the pipeline is coated with the coating, since coating is carried out manually, the coating at the lower end surface of the pipeline is inconvenient to coat, a coating effect of the coating is poor and non-uniform, and the coating operation is easily missed; and the anti-corrosion and heat-insulation processing method for the petroleum pipeline provided by the invention has the advantages that the coating is good in coating effect and uniform in coating, the pipeline is prevented from being damaged, and the like.

Description

technical field [0001] The invention relates to the technical field of pipeline anticorrosion, in particular to an anticorrosion and heat preservation treatment method for oil pipelines. Background technique [0002] As one of the important energy sources, petroleum has played an extremely important role in the rapid development of the social economy, but there are still some problems in the construction of oil and gas pipelines. After a long period of use of oil pipelines, it will cause corrosion, perforation and leakage of the pipelines, which will give It will bring harm to the public and the environment, seriously affect the development of enterprises, and reduce the economic benefits of enterprises. How to ensure the anti-corrosion effect of oil and gas pipelines is an important issue faced by enterprises now. [0003] The existing oil pipelines usually have the following defects when anticorrosion treatment is carried out: 1. The surface treatment effect of the pipeli...

AI Technical Summary

Problems solved by technology

[0005] The invention can solve the problem that when the existing oil pipelines are subjected to anticorrosion treatment, the treatment effect on the surface of the pipeline is poor, and impurities such as oil stains, rust, and welding slag on the outer surface of the pipeline are not treated cleanly, resulting in poor adhesion of the anticorrosion coating and easy corrosion of the anticorrosion layer. Shedding occurs, and at the same time, when the coating is applied to the surface of the pipeline, it is usually applied manually. It is inconvenient to apply the coating on the lower end of the pipeline, and the coating application effect is poor, uneven, and prone to leakage.
