What is the scaling and corrosion situation on the outer wall of your wet air-cooling tube bundle? What are the requirements for water quality?

1. Corrosion is greatly affected by water quality. . . 2. Deoxygenated softened water should be used as much as possible, and a recovery and recycling system should be set up. . . 3. If your groundwater is soft or not very hard, you can use tap water or fresh well water. . . :lol

When in contact with air, it contains a lot of oxygen and is prone to corrosion, so it requires a professional company to add an additive treatment solution.

Air cooling, air cooling, needs to be in contact with the air. It is correct to use demineralized water on the second floor. Then remove oxygen.* * Wrong. Lanzhou Petrochemical also experienced this kind of problem. Later, it added softened water corrosion inhibitor, and the effect was much better. contact me

We use softened water here and have a water tank for recycling and power replenishment. No scaling was found.

Sometimes corrosion is not only caused by external factors, but it can be serious if it is caused by internal and external factors. For example, the medium passing through the inside is more corrosive, such as water injection is more acidic.

The outer wall of our air cooling is severely corroded, and our air cooling uses desalted water. .

Demineralized water must be used for wet air cooling. Affected by the surrounding environment, with evaporation and concentration, the pH value of the water quality can be reduced to a minimum of about 3.5, causing external corrosion to the equipment. Generally, the pH value is controlled between 7 and 9, and the water is replaced regularly to ensure that the water quality is qualified.

We use demineralized water, and use one common water tank for multiple units, which is recycled. The water tank is regularly discharged every day, and the demineralized water is replenished. There was serious scaling in the past, but after the implementation of scheduled arrangements, no obvious scaling was found.
