About anti-corrosion coatings for heat exchange equipment

Author:


Summary:

During the use of heat exchange equipment, the heat exchange surface faces complex medium corrosion, as well as threats from high temperatures and high flow rates. Additionally, the coating increases thermal resistance, leading to a decrease in heat transfer efficiency. Therefore, a good anti-corrosion coating should have good adhesion, low thermal resistance, and good temperature and corrosion resistance for different fluid media. Currently, the high-temperature organic silicon anti-corrosion coating applied by Saiwei Company on flue gas heat recovery exchangers has shown good results.
