Anti-corrosion requirements for high-temperature resistant anti-corrosion coatings for industrial pipelines: 1. Excellent adhesion, including adhesion tests across all possible operating temperature ranges of the equipment. It is divided into normal temperature, alternating cold and heat phases, and high-temperature operation phases. 2. It exhibits excellent mechanical properties under various temperature conditions, such as high temperatures, alternating hot and cold environments, and normal temperatures; its hardness, toughness, adhesion strength, etc., meet the required standards. 3. Corrosion resistance. Identify the corrosion factors based on the surrounding environment, such as industrial environments, buried conditions, or high-humidity river and marine environments, etc. Selection of high-temperature resistant anti-corrosion paint for industrial pipelines: 1. The inorganic zinc-rich primer is suitable as an anti-corrosion coating for the outer walls of pipelines at temperatures below 400°C; it can be used in combination with silicone-based high-temperature resistant topcoats. 2. Epoxy phenolic paint is used as a primer and topcoat for the anti-corrosion protection of the outer surfaces of carbon steel, cast iron, and stainless steel pipes at temperatures below 200°C; it is recommended for use on pipes with insulation layers. 3. The high-temperature resistant anti-corrosion paint for industrial pipelines is suitable for protecting the outer walls of pipelines operating at temperatures between 200 and 800°C; it can be used whether the pipelines have insulation layers or not
