Selection of anti-corrosion coatings for industrial steel pipes

There are many types of anti-corrosion coatings, and their performance and uses are different. Correct selection is crucial to the anti-corrosion effect and service life of the coating. The following should be considered when selecting:

1. The properties of the surface material of the coated object: For example, iron red and red lead primers can be selected for ferrous metals, while red lead primers not only do not protect non-ferrous metals such as aluminum but will damage them.

2. The use environment of the coated object: Anti-corrosion coatings are highly targeted to the environment. The most suitable coating variety should be selected according to the specific use environment, such as the type, concentration, temperature of the medium, and the operation of the equipment.

3. Construction conditions: The appropriate coating variety should be selected according to the actual conditions of the construction site. For example, solvent-free high-solid, or water-based anti-corrosion coatings should be used for construction on sites with poor ventilation conditions. Only self-drying coatings can be used on sites without baking and drying.

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