【Weekly Topic】12.28~1.3: How to control corrosion at the source in engineering management?
Thread Content
How can corrosion be controlled at the source in engineering management? For example, stages such as design, bidding, and construction.
1. Select metal and non-metal materials appropriately based on the application environment； 2. Conduct reasonable structural and process design for the product in order to reduce corrosion during processing, assembly, storage, and other stages ； 3. Adopt various measures to improve the corrosion environment, such as using corrosion inhibitors in closed or circulating systems, as well as degassing, deoxygenation, and desalination ； 4. Adopt chemical protection methods, including cathodic protection and anodic protection techniques ； 5. Apply a protective coating to the substrate, including metal coatings and non-metallic coatings.
It is important to control corrosion during the construction phase; do not wait until corrosion occurs before carrying out sandblasting, as this is costly and time-consuming.

Controlling corrosion: Consider the operating conditions during design, and select an appropriate corrosion margin to increase wall thickness, etc； During the bidding process, purchases are made in strict accordance with the design requirements; within the limits permitted by the standards, manufacturers are requested to supply products with a positive deviation, especially for items such as steel pipes ； During construction, be thorough and careful; promptly apply repainting to areas where pipes are scratched or damaged. do
Select appropriate corrosion-resistant materials and structures, such as galvanized steel components and concrete structures. Choose suitable anti-corrosion coatings and treatment methods, such as those for protecting buried pipelines, the bottoms of storage tanks, and providing cathodic protection for storage tanks. Ensure a reasonable cost for anti-corrosion measures; only with an appropriate budget can the necessary work be carried out – without it, the desired level of protection cannot be achieved

Ensure a reasonable cost for anti-corrosion measures; work can only be carried out if there is funding, otherwise the desired level of protection cannot be achieved. Planning should be done from the beginning to avoid having to redo the work later
1. Rational design, substrate selection, structure, and application of anti-corrosion techniques. 2. Anti-corrosion processes and strict supervision. 3. Proper use and maintenance
