Because seawater desalination equipment has to be in contact with seawater for a long time, the data used must have outstanding corrosion resistance. Seawater desalination equipment uses a variety of materials, commonly used shell, heat transfer data are carbon steel, stainless steel, titanium tube, copper tube, aluminum tube and so on. What is the corrosion resistance of seawater desalination equipment? Now let's follow the desalination equipment manufacturers to understand.

1. The corrosion type of cast iron in sea water is called graphite corrosion, which means that the iron on the surface of cast iron is corroded.

2. The relative corrosion rate of stainless steel in seawater is low, and most of the appearance is not easy to be corroded.

3. Aluminum alloy has high strength and seawater corrosion resistance, and is widely used in Marine environment.

4. The strength of titanium tubes is higher than that of metal tubes. There is a strong adhesion oxide film on the surface of titanium, which protects the titanium tube from corrosion. Even if the titanium tube is mechanically worn, it can heal or regenerate itself.

In order to reduce the corrosion of seawater desalination equipment, we usually apply maintenance coating data to the equipment. Protective coating data mainly include metal zinc, tin, cadmium, lead and aluminum. Non-metallic inorganic oxide, milk fat. There are three categories: organic coatings, polymer compounds and plastics. These protective coating materials have excellent adhesion, can block the penetration of environmental media, and play a role in maintaining seawater desalination equipment.

When selecting the data of seawater desalination equipment, try to select the best anti-corrosion data, or adopt anti-corrosion methods for seawater desalination equipment to ensure the long-term stable operation of seawater desalination equipment. The above is about the corrosion resistance of seawater desalination equipment.
