This post was last edited by passionzq on 2016-1-8 15:07. Methods for corrosion control: 1. Select metal and non-metal materials appropriately based on the environment in which they will be used； 2. Conduct reasonable structural and process design for the product in order to reduce corrosion during processing, assembly, storage, and other stages ； 3. Adopt various measures to improve the corrosion environment, such as using corrosion inhibitors in closed or circulating systems, as well as degassing, deoxygenation, and desalination ； 4. Employ chemical protection methods, including cathodic protection and anodic protection techniques ； 5. Apply a protective coating to the substrate, including metal coatings and non-metal coatings.
The heat exchanger tubes and tube sheet are joined by expansion welding to prevent gap corrosion.

Upgrade material grade； Apply an anti-corrosion coating ； Cathodic protection, etc
The main methods for controlling corrosion are: ① Applying a protective coating or film to protect the inner wall of the pipeline； ②Cathodic protection is used to protect the outer wall of underground pipelines (see water supply network maintenance) ； ③Corrosion inhibitors are added to water and are commonly used in circulating cooling water systems to protect both the inner walls of pipes and the surfaces of heat exchange equipment that come into contact with water; ④ Corrosion-resistant pipe materials such as galvanized steel pipes, plastic pipes, and asbestos-cement pipes are used.
