Discussion based on the diagram—why is it necessary to protect the metal surface on the circulating water side of the tubes in petrochemical water coolers from corrosion?
Thread Content
The image below shows the corrosion and rust scaling on the circulating water side of the cooler tube bundle in the petrochemical industry.
The metal surface on the circulating water side of the tube bundles in petrochemical coolers needs to be treated to prevent corrosion. This is because, in the circulating water system, impurities such as oxygen, salts, and microorganisms present in the water can undergo chemical or electrochemical reactions with the metal, leading to metal corrosion and the formation of rust. These corrosions and rusting not only reduce the service life of the pipes, but also lower heat exchange efficiency, increasing energy consumption and operating costs. By applying anti-corrosion treatments, the metal surface can be effectively protected, the service life of equipment can be extended, and high operational efficiency can be maintained. .
