Correct Answers:
A. Using corrosion-resistant materials or alloys for construction.
B. Installing sacrificial anodes in the cooling system.
C. Applying protective coatings to internal surfaces.
D. Regularly cleaning the cooling system to remove debris and biological growth.
Explanation:
- A. Using Corrosion-Resistant Materials or Alloys: Correct. Utilizing materials that are resistant to corrosion, such as stainless steel or specialized alloys, helps to prevent the onset of corrosion in seawater cooling systems.
- B. Installing Sacrificial Anodes: Correct. Sacrificial anodes are used to protect other metal parts of the cooling system from corrosion. They corrode preferentially due to their higher electrochemical potential.
- C. Applying Protective Coatings: Correct. Coatings can create a protective layer on internal surfaces, preventing direct contact with seawater and reducing corrosion.
- D. Regularly Cleaning the Cooling System: Correct. Cleaning the system helps remove debris and biological growth, which can cause localized corrosion and blockages.
- E. Increasing the Temperature of the Seawater: Incorrect. Higher temperatures can actually accelerate corrosion rates rather than minimize them. Maintaining moderate temperatures is usually preferable.
- F. Reducing the Flow Rate of Seawater: Incorrect. Reducing flow rate can lead to stagnation and increased risk of fouling and localized corrosion. Proper flow is necessary to keep the system clean and effective.
