Technical Field

On-site investigation has found that, in the case where the pipelines in the buried part and the house part are not seriously corroded, the pipelines in the place-out part mostly show serious corrosion damage within only a few years of installation and use. Taking a pipeline as an example, the parts of the buried pipeline exposed out of the ground are seriously corroded, and the corrosion is particularly serious at the connecting parts (usually adopted for connection) of the underground pipeline and the pipeline above the ground; even a certain number of pipelines are locally rusted and perforated at the position close to the underground pipeline, so that great potential safety hazards exist, and the operation safety of a pipe network is seriously influenced.
Corrosion of the pipeline can lead to unplanned maintenance, replacement, and unplanned downtime of the pipeline equipment, resulting in direct and indirect economic losses. Serious local corrosion easily causes the pipeline perforation to generate leakage accidents, besides polluting the environment, also can cause explosion and fire, and once the accidents occur, serious casualties and serious property loss can be caused. Therefore, it is necessary to apply an effective anti-corrosion treatment to the flange of the pipe valve as early as possible, which is necessary for economic and safety analysis.
