1.
Steel pipeline anticorrosion generally adopts two main methods of external coating and cathodic protection.
2. Although most of the surface of the steel pipe is covered by the coating, a slight leak will cause an incredible corrosion rate, or even perforation or cracking. Therefore, in the anticorrosion of steel pipelines, the coating system and cathodic protection are generally used in combination to achieve a coverage rate of 99.99%, to avoid unimaginable results in the future.
3. The cathodic protection used for steel pipeline anticorrosion is divided into dedicated cathodic protection and impressed current cathodic protection.
4. The purpose of the anti-corrosion coating of
3PE anti-corrosion steel pipes is to form a continuous covering layer of insulating material, which directly insulates the metal and the electrolyte in direct contact with it so that the correct electrolytic reaction cannot occur.
5. The discontinuous points in the coating laying process are called leaking points. The main reasons for the occurrence are during coating, transportation, or installation, and it may also be caused by coating aging, soil stress, or pipeline movement in the soil.
