Description

technical field [0001] The invention relates to the technical field of pipeline transportation and anti-corrosion, in particular to a preparation method of a green anti-corrosion pipe wall film. Background technique [0002] In pipeline transportation, liquid is usually transported in steel pipes. For different forms of fluid, although the composition of resistance is different, the cause of resistance loss is the energy dissipation of fluid during motion. Secondly, pipeline corrosion often occurs during pipeline transportation, and pipeline corrosion will cause great restrictions on engineering transportation. It is not only necessary to regularly check the safety performance of each section of pipeline, but also to replace existing problems regularly. The corrosion of pipelines has greatly consumed manpower and material resources. Contents of the invention [0003] The purpose of the present invention is to enhance the anti-corrosion ability of the pipeline, reduce the ...
