Selection of anti-corrosion coatings for steel pipes
There are a wide variety of anti-corrosion coatings, and their properties and uses are different. Correct selection is crucial to the anti-corrosion effect and service life of the coating. When choosing, you should consider:
1. Surface material properties of the coated object
For example, ferrous metals can choose iron red and red red primers, and red red primers not only have no protective effect on non-ferrous metals such as aluminum, but will play a destructive role.
2. The use environment of the coated object
Anti-corrosion coatings are highly targeted to the environment, and the most suitable types of coatings should be selected according to the specific use environment, such as the type of medium, concentration, temperature, equipment operation and other factors.
3. Construction conditions
Appropriate paint varieties should be selected according to the actual conditions of the construction site. Solvent-free or high-solid or water-based anti-corrosion coatings should be used for construction on site with poor ventilation. Only self-drying coatings can be used on sites where there is no bake-drying facility.
4. Comprehensive effect of technology and economy
It is not only necessary to consider whether the technical performance is excellent, but also the rationality of the economy. In economic accounting, material costs, surface treatment costs, construction costs, coating performance and service life, and maintenance costs should be comprehensively considered.
