There are many kinds of steel pipe anti-corrosion coatings, and their properties and uses are different. The correct selection is very important for the anti-corrosion effect and service life of the coating. When choosing, you should consider: 1. The properties of the surface material of the object to be coated: iron red and red lead primers can be selected for ferrous metals, and red lead primers not only do not protect non-ferrous metals such as aluminum but will have a destructive effect. 2. The use environment of the coated object: Anti-corrosion coatings are highly targeted to the environment, and the most suitable coating variety should be selected according to the specific use environment, such as the type, concentration, temperature, and equipment operation of the medium. 3. Construction conditions: Appropriate coating varieties should be selected according to the actual conditions of the construction site. Solvent-free or high-solids or water-based anti-corrosion coatings should be used for construction on sites with poor ventilation conditions. Only self-drying paint can be used in a field that does not have baking drying. 4. Comprehensive effect of technology and economy: Not only should the technical performance be excellent, but also economic rationality should be considered. When conducting economic calculations, material costs, surface treatment costs, construction costs, coating performance, service life, and maintenance costs should be considered comprehensively.
