Everyone, take a look at why this is the case

This is a full-liquid evaporator for a refrigeration machine; liquid ammonia flows in the shell side, while the refrigerant hexane flows in the tube side. The image below shows the refrigerant inlet piping. What I don’t understand is why the refrigerant pipes, which are made of 16MN material, still need to have anti-corrosion paint applied to their surface
Looking forward to it. Why can’t it be preserved?
Isn’t this type of corrosion protection usually applied in underground installations?
Generally, it follows the insulation design specifications of the refrigeration industry. When in use, the coolant undergoes heat absorption exchange on the tube walls, so anti-corrosion treatment is required. It’s the same principle as the condensate water from air conditioners.
1. Low carbon emissions. 2. Corrosion resistance (against electrochemical corrosion caused by salty and alkaline air in coastal areas). 3. Corrosion protection is necessary when the pipes are buried. 4. The medium inside the pipes causes the outer surface of the pipes to sweat frequently, making electrochemical corrosion highly likely to occur.
The statement on the 5th floor is absolutely correct; corrosion prevention is essential
