Introduction to a carbon steel tube bundle with a metal nanocoating

Thread Content

Metal-nanocoated carbon steel tube bundles. According to incomplete statistics, in modern large-scale production facilities, especially in integrated production systems for petroleum refining, chemicals, fertilizers, and chemical fibers, various types of heat exchangers are constantly performing the function of converting and transferring thermal energy. According to statistics, heat exchangers account for 20-40% of the total investment in equipment. In industries such as petroleum refining, chemicals, and fertilizers, thousands of heat exchangers are rendered unusable each year due to corrosion and scaling, resulting in losses of around several hundred million yuan. Severe corrosion and scaling of the heat exchanger greatly impair its heat transfer efficiency, resulting in significant energy waste. Damaged heat exchangers not only lead to frequent maintenance and replacement tasks, as well as leaks of raw materials and products, posing threats to human health and causing environmental pollution, but they also result in plant shutdowns due to accidents, which incur significant losses in production. If no anti-corrosion measures are taken for the carbon steel heat exchange tube bundles in the petrochemical industry, they become unusable after 1–3 years of use. At the same time, a large amount of rust buildup forms outside the tubes, severely restricting the heat exchange efficiency of the heat exchanger. The use of a “metal nanocoating heat exchange tube bundle” can increase the service life of carbon steel tube bundles by 2 to 3 times. The following shows the performance of the anti-corrosion coating on the carbon steel tube bundle of the water cooler after 3 years of use.
