The anti-corrosion treatment of carbon steel storage tanks directly affects equipment life and operational safety. Targeted protective measures need to be taken according to different usage environments, which are mainly divided into the following3Big plan:

       1. Inner wall anti-corrosion solution

       Epoxy coating: suitable for neutral media such as water and oil. It is low cost and easy to construct. It needs to be inspected and recoated regularly.

       Rubber lining: resistant to acid and alkali corrosion, suitable for chemical wastewater storage, but the installation process requires high requirements.

       Fiberglass lining: excellent comprehensive performance, can withstand a variety of chemical media, and has a long service life.

       2. Exterior wall anti-corrosion solution

       galvanized+Spray paint: hotgalvanizedProvides basic rust protection, combined with polyurethane topcoat to enhance weather resistance, suitable for outdoor environments.

       Epoxy coal tar pitch: suitable for wet or buried storage tanks with a long anti-corrosion period.

       3. Special parts protection

       Welding seam treatment: Use anti-corrosion tape or reinforced coating to avoid preferential corrosion of the welding joint.

       Bottom protection: Install sacrificial anode blocks to avoid electrochemical corrosion.

       Maintenance recommendations: at least annually1A thorough inspection was conducted and any damage to the coating was found to be repaired in a timely manner. In a highly corrosive environment, the maintenance cycle needs to be shortened to6months.

       Summary: Reasonable selection of anti-corrosion solutions and regular maintenance can greatly extend the life of carbon steel storage tanks and reduce comprehensive use costs. When selecting, the media characteristics, environmental conditions and budget need to be considered comprehensively.
