Key links to controlling corrosion
Design, construction and management are three important links to controlling corrosion.
1) Design is the first link to controlling corrosion, including the correct selection of anti-corrosion technology, the reasonable selection of corrosion-resistant magnesium anodes and the reasonable design of equipment structure.
2) Magnesium anode construction is an important link that determines whether various anti-corrosion measures can achieve the expected anti-corrosion effect.
3) Management, including construction management and operation management.
Corrosion control technology
1) Reasonable design: including overall design and detailed design.
2) Correctly select magnesium anode anti-corrosion materials. At present, equipment and pipelines are still mainly made of metal materials. The purpose of material selection is to meet process requirements and corrosion requirements more economically.
3) Change the corrosion environment: The purpose of changing the corrosion environment is to reduce the corrosiveness of the medium and remove harmful impurities in the medium.
4) Use corrosion-resistant covering layer: Use a metal or non-metallic material covering layer with corrosion resistance on the surface of the base metal to isolate the medium from the metal base. It is a widely used anti-corrosion method.
5) Electrochemical protection: In most cases, metal corrosion is due to the action of corrosion cells, which is electrochemical corrosion.
6) Replace metal materials with corrosion-resistant non-metallic materials: Using non-metallic materials with good corrosion resistance to manufacture equipment, pipelines and components is a promising anti-corrosion method.
