When considering corrosion protection for the tube bundles of petrochemical water coolers, it is necessary to take into account the corrosion resistance of both the inner and outer walls

Thread Content

The image below shows the anti-corrosion treatment of the tube bundle in a water-cooled gasoline cooler used in petrochemical industries. It can be seen from the image that there is still a difference in corrosion resistance between the side exposed to circulating water (inside the tubes) and the side exposed to gasoline. Therefore, for tubes where corrosion protection of both the inner and outer walls is required, a comprehensive consideration must be given.
