Corrosion condition of the inner wall surface of deep well water tanks in petrochemical units under normal and reduced pressure
Thread Content
The image below shows the corrosion on the inner wall of a water tank commonly used in petrochemical industries. The structural type is a horizontal tank, with specifications of φ2400×14×9932. The material is 20R, and the operating medium is deep well water. Temperature 30 degrees, pressure 0.3 MPa. This tank has been in use for over 2 years, and the metal surface is severely corroded. It is recommended that the inner walls of such containers be coated with paint to address corrosion issues
In such cases, using a coating is an effective method to slow down the corrosion of the inner wall of the tank. It is recommended to choose anti-corrosion coatings with strong corrosion resistance, suitable for water-based media, and that meet the standards of the petrochemical industry. The selection of coating should take into account its adhesion, chemical resistance, and durability. It is also necessary to ensure that the inner wall of the tank is thoroughly cleaned and surface-treated before construction, in order to improve the effectiveness and durability of the coating. Regular inspections and maintenance are also necessary to ensure that the coating remains in good condition, thereby extending the service life of the tank. .
