Corrosion of the gasoline water cooler tube bundle in petrochemical refining units
Thread Content
The diagram below shows the tube bundle of a gasoline water cooler, with an operating temperature of around 130 degrees and a pressure of 1 megapascal. Corrosion condition of the carbon steel tube bundle after more than 2 years of use due to corrosion by the HS-HCl-H2O system. It severely affects the service life of the tubes and the heat transfer efficiency of the heat exchange equipment. It severely affects the safe operation of chemical processing units. Therefore, the research on the corrosion and protection of carbon steel pipe bundles has always been a topic of study for our anti-corrosion engineers.
Please ask experts to suggest some anti-corrosion strategies or solutions, such as coating, nickel-phosphorus plating, or upgrading the material. . . This phenomenon is still quite common nowadays
Change the material to duplex steel.
