Selection of anti-corrosion coatings for industrial steel pipe

There are many types of anti-corrosion coatings with different properties and uses. The correct selection is crucial to the anti-corrosion effect and steel pipe service life of the coating. When choosing, you should consider:

1. Material properties of the surface of the object to be coated
For example, for ferrous metals, you can choose iron red or red lead primers. Red lead primers not only have no protective effect on non-ferrous metals such as aluminum but will instead have a destructive effect.

2. The usage environment of the painted object
Anti-corrosion coatings are highly targeted to the environment. The most suitable coating type should be selected based on the specific use environment, such as the type of medium, concentration, temperature, equipment operation conditions, and other factors.

3. Construction conditions
The appropriate coating variety should be selected based on the actual conditions of the construction site. For construction on site with poor ventilation conditions, solvent-free or high-solids or water-based anti-corrosion coatings should be used. Only self-drying coatings can be used on sites that do not have baking and drying capabilities.

4. Comprehensive effects of technology and economy
Not only should the technical performance be considered excellent, but also the economic rationality should be considered. When conducting economic calculations, material costs, surface treatment costs, construction costs, coating performance and service life, maintenance costs, etc. must be comprehensively considered.
