Use of Anti-Corrosion Coating on Heat Exchanger Is an Effective Way

In order to prevent industrial cooling water cause corrosion and fouling of heat transfer equipment, use of anti-corrosion coating on heat exchanger is an effective way. Practice has proved that this new product has a good practical effect and broad application prospectsa. Many sectors of modern industry is extensive use of various heat exchanger, where the vast majority of cooling water as a cooling medium. The heat exchanger is an important equipment in the petrochemical industry, it accounting for 20% of the capital investment costs and accounting for 40% of the total weight of the process equipment. Due to the harsh and adverse use conditions in the production process, under the action of high-temperature liquid, gas or multiphase corrosive media corrosion and erosion, the heat exchanger is easy have crevice corrosion, perforation and leakage, which will shortened life expectancy of heat exchanger and resulting in huge economic losses. Anti-corrosion of the heat exchanger used mainly corrosion-resistant materials, organic paint protection, electrochemical protection, high temperature aluminized, infiltration of zinc, organic paint protection is the most economical and effective way. Now, there are many varieties of protective coatings for heat exchangers, and most in need of high temperature curing of thermosetting coatings, it save costs, construction process is simple and excellent corrosion resistance at room temperature. In the heat exchanger put into use in the past few months, the practice has proved that polyurethane anti-corrosion paint is a technology leadership and excellent performance corrosion protection material, it use of polyurethane anticorrosive paint anticorrosive coating the inner wall of the heat exchanger tube is a simple construction, high efficiency, stable and reliable quality of the coating corrosion.
