1. Seawater contains a lot of chloride ions, so most stainless steel materials cannot be used, and carbon steel is seriously corroded. The material of seawater heat exchanger is generally titanium alloy.
2. Titanium plate is the best material for seawater heat exchanger, but its price is higher. 254SMO stainless steel is also used. At a slightly higher temperature, 254SMO also has a high crevice corrosion resistance in seawater.
3. Copper and copper alloy materials can also be used in seawater heat exchangers, but at present they are only used in seawater culture.
4. When the chloride ion concentration is low, it is better to use aluminum brass as seawater heat exchanger.
5. A heat exchanger is a device that transfers part of the heat from a hot fluid to a cold fluid, also known as a heat exchanger. Heat exchanger plays an important role in chemical industry, petroleum, electric power, food and many other industrial production. They can be used as heaters, coolers, condensers, evaporators and reboilers in chemical production and are widely used.
