Corrosion problem of heat exchanger tube bundles
Thread Content
One method of preventing corrosion in heat exchangers is to take into account the process parameters related to the process medium throughout the entire system; additives such as corrosion inhibitors are used in the fluid being processed in order to control the factors that can cause corrosion of the equipment. Practice has shown that it does indeed suppress metal corrosion, but the corrosion in some equipment remains difficult to control, with the equipment’s service life being significantly reduced; heat exchanger tubes suffer from such a problem. Therefore, to address corrosion of the heat exchanger tube bundles, people have always been looking for surface coatings to solve this problem. The following two images show the tube bundle (gasoline cooler) after use in the petrochemical industry.
To effectively address the corrosion issue of heat exchanger tubes, using corrosion-resistant surface coatings is a common and effective method. By applying a specific coating to the surface of the tube bundle, its resistance to corrosive agents can be enhanced, thereby extending the service life of the equipment. .
Please specify what grade of material is used for the coating； How effective it is (there are photos if it worked well).
