Electrochemical sacrificial anode anti-corrosion measures can be employed on the circulating water side of the tube bundle in petrochemical coolers
Thread Content
The issue of corrosion in the tube bundles of water coolers in petrochemical plants is a topic that cannot be ignored. Because water on the circulating water side causes metal corrosion, which is a common problem. Currently, the main method used for corrosion protection of carbon steel pipe bundles is coating with paint. However, after anti-corrosion treatment, problems such as coating damage can occur in the tube bundle during use, leading to corrosion; in severe cases, the cooling tubes corrode rapidly (due to anodic-cathodic electrochemical corrosion). It is difficult to repair a damaged coating. To address such problems, electrochemical sacrificial anode corrosion protection measures can be employed, which yield good results. The following figure shows the layout of the anode blocks in the water cooler.
Electrochemical sacrificial anode protection can be employed to address the corrosion issue on the circulating water side of the tube bundles in petrochemical water coolers. .
This is indeed quite practical and can provide excellent anti-corrosion effects.
