For solving corrosion problems with water coolers (used in seawater circulation systems), turn to me. I have research experience and practical knowledge from working with over 30 petrochemical plants in China, and I’m happy to share it

How to address corrosion in circulating water coolers, especially those operating at high temperatures.

Circulating water cooler, water side temperature 80°C, highest corrosivity. Under normal circumstances, it is rare for temperatures to reach this level. Is there any issue with the waterproofness of the anti-corrosion coating (layer) on water coolers? The key lies in finding the optimal balance between flexibility and strength – that is, having sufficient toughness along with excellent strength. Durability – it can withstand deformation that occurs during the lifting and installation of the water cooler, as well as during the passage of tubes through the bundle (core); it prevents the coating from deforming, which could lead to cracking and peeling. It also protects against damage to the coating’s adhesion caused by turbulent flow in the tubes used in the water cooler, thereby avoiding delamination and peeling ; Strength – refers to the ability of the coating to withstand scouring by circulating water on the water side, as well as by medium-pressure water during maintenance work. Of course, the coating’s resistance to chemicals (such as various scale and corrosion inhibitors added to circulating water) and its tolerance to small amounts of oil leakage are the most basic aspects, and there’s no need to emphasize them. Let’s talk about these first. It can be discussed if it’s not appropriate.
