RESEARCH ON THE FAILURE OF CATHODIC SHIELDING AND ANTI-CORROSION OF BURIED METAL PIPES
At present,the most common and effective method to the corrosion issue of buried metal pipes is to surface-coat them.The organic coatings commonly used have the disadvantage that the corrosion resistance decreases rapidly as the coating ages.Based on the Suizhou pipeline project,this article analyzes the anti-corrosion coating of the metal equipment in the pipe to obtain the reasons for the failure of the anti-corrosion coating,analyzes the causes of cathode shielding under the cathodic protection system,selects reasonable coating construction technology,and reduces the number of anti-corrosion coatings.Provide reference for similar projects.
