For petrochemical water coolers, the differences in corrosion resistance between those with and without anti-corrosion measures are significant when the operating conditions on the circulating water side are the same

The image below shows the circulating water side of the tube bundle in a petrochemical water cooler; under the same operating conditions for the different tube bundles, there is a significant difference between those with anti-corrosion measures and those without them.
Mr. Wang, I have a question: 1. By corrosion protection, do you mean the protection of the inner surface of the heat exchange tubes and the tube sheets? 2. Isn’t normal circulating water treated with chemicals? Are the debris in the image pollutants in the water or corrosion products of the tubes? 3. If anti-corrosion treatment is to be applied to the inner wall of the heat exchange tube and the tube sheet, what methods are used? Thank you!
In petrochemical water coolers, if the tube bundle is treated for corrosion protection, its corrosion resistance and service life are significantly improved； Unprotected tube bundles, affected by corrosion, are prone to damage and blockages, thereby affecting the efficiency and safety of the entire system. Therefore, the difference between anti-corrosive and non-anti-corrosive materials is mainly reflected in corrosion resistance and equipment stability. .
