It refers to the carbon steel storage tanks used in petrochemical units for atmospheric and vacuum distillation; the operating conditions are a temperature of 50 degrees and a pressure of 0.15 MPa, the material used is carbon steel, and the specifications are φ1500×10×6504. The media are gasoline, oil and gas, and water. Due to corrosion by Cl-H2S-H2O, the metal surface is severely corroded. It is recommended to apply a paint coating to such containers for corrosion protection, which yields very good results.
Severe corrosion of the inner wall of vacuum carbon steel product tanks in the petrochemical industry may be caused by factors such as the medium stored in the tanks (e.g., acidic or alkaline substances), temperature, and pressure, which accelerate the corrosion process of the inner wall. Regular inspection and anti-corrosion treatment are required. .
